Hi Tammy, thank you for your note and input. To make the clay softer can be achieved in one of four ways:
1) Recycle / reclaim it: Slice it to 1/2" slices and place in bucket of water for a couple of days. Then, place in a plaster board (the best way) or plywood to let it dry to the right consistency, Then wedge well.
2) Soften it: Make many holes with your finger or a tool (e.g., like Swiss cheese). Place in water over night and wedge well.
3) Let it get completely dry, break with a hummer and let is soak in water. Then follow the process described in note #1 above
4) Buy new clay!

Hi Michelle, a very good question. We do not publish recipes that we us and do not belong to us (may belong to one of the artists in our studio that prefer to keep it to themselves. Which glaze are you interested in specifically? We might guide you to where you can purchase the equivalent. Kindly, Morty and Patty
--------------------------
Dear Lakeside Pottery, I have been potting for several years in a studio and have decided that I would like to more fully explore mixing my glazes and firing in my own kiln.
I am getting a bit frustrated glazing in a studio where the mixture of any glaze changes seem to change from week to week due to contamination, etc.
There are several glazes that I see listed in your unpublished glazes that I am interested in the recipe. I am wondering what determines whether you publish the recipe and whether the recipes can be purchased?
Thank you very much. Michele

I want to purchase a used kiln. I was an art major in college, that was 40 yrs ago, so I am familiar with clay types, but never got experience stacking a kiln. So, low fire, high fire, temps and cones are rather unfamiliar to me at this point.
I would like to start with a small to medium size kiln, (price is an issue, $250 range or lower) as I have turned some small items and have done some small hand built objects, low fire, at this point, but might be working with high in the future. What do I need to be aware of when purchasing one used.
Your website was very useful and informative, but I feel that I need to simplify the info for my use at this point...
Thanks so much...
I also acquired a lot of glaze powders with chemical additives, which I would like to experiment with, but of course would not do this without some local expert advice...risky, to say the least...
Thanks again....and will definitely save your site to my favorites...

Hi Keith, thank you for your note. Yes, we restore a wide range of ceramic or sculpting work, small, large, antiques and modern. To be able to determine what is required and to provide you with an approximate estimate, please forward the following:
1) Dimensions (approximate) and how many units?
2) A couple of clear pictures (to be e-mailed)
3) Do you have all the broken pieces?
4) Where are you located?
As far as coloring the repaired area, it is years of experience knowing to make the right choices and process on a case by case basis. Most paintings requires several additives and several layers each different from the previous one using various techniques (brush, spray, dipping, and more). I could not possibly teach you this via e-mail - so sorry! Kindly, Patty and Morty

Its mostly the touching up of small amounts of flaking paint.
My wife has a few larger pieces that are worth real money if perfect ,however as they are over 30 years old they are looking a little tired.
do you get involved with small stuff like this?.
Can you tell me how I would acquire the type of paint used on this type of figure ?.

I fired a water jug and there is a small crack in the connection between the base of the spout and the body of the jug, such that water leaks when it leaves the jug and enters the spout. I thought I could apply epoxy at the external base of the spout to seal the connection and stop the leaking. The jug is glazed. I would want a clear epoxy, but your article suggests that epoxy yellows. Questions: Would you recommend epoxy? Is there a clear epoxy? Would you drink from the jug after epoxy has been applied?
Thanks.

Hi Joan, good question and we'll add this answer to our tutorial for others to read.
In your case, PVA is probably a better choice mainly because you leave the repaired surface untreated or untouched. The bonding principal of PVA is that it soaks into porous materials such as old ceramic, bones, wood, etc. For best adherence strength and longevity, use the proper PVA viscosity (V15 or V25 for porous ceramic).
The benefits of PVA (Polyvinyl Acetate) are:
1) Will not yellow and has good stability to light (UV)
2) The gluing job can be reversible meaning, the glue will remain soluble and can be easily removed from a repaired subject later and be ready for re-gluing.
3) Easy to work with and easy to clean up
4) Low cost
The disadvantages of PVA:
1) Medium bonding strength (way less than new modern epoxies)
2) Cemented item can fail in humid, cold or hot storage
3) Will not work with non-porous objects
4) PVA shrinks and therefore will: a) distort repaired objects with thin walls and b) the repaired gap will be recessed a bit after drying
5) When dry, can leave a shiny outer surface which can be eliminated by wiping the surface with a lint free cloth saturated with PVA solvent (e.g., acetone).
We use mostly epoxy resins because:
1) Most projects that come our way use non-porous ceramic that makes PVA not suitable
2) Most projects we work on require complete restoration including color retouching. We use acrylic base finishing that will not discolor. Therefore the discoloring properties of epoxies is irrelevant.
3) Epoxy does not shrink as it cures
4) Epoxy has extremely strong bonding qualities
5) Epoxy does not chemically interact or effect acrylic finishing
6) Epoxies come in various options in terms of curing time and colors
7) Epoxies can be a filler and is workable (drilling, sanding, polishing)
Epoxy disadvantages:
1) Will yellow with time and can be an issue with restoration that does not require color re-finishing
2) Removing epoxies is difficult and therefore is not considered "reversible"
3) More expensive
4) Managing mixing two parts can be messy and wasteful
5) Tooling and working surface clean-up is more labor intensive
6) Strong smell and potential health issues when applying
As a general rule, epoxy resins should be avoided for archeological restoration. However, epoxies are occasionally required by conservators because nothing else has the required bonding strength. They are excellent when a very strong and permanent bond is required.
Hope the above helped. Kindly, Patty and Morty

Hi. Thank you for posting your tutorial on repairing ceramics. I am a
member of a local historical society, and have been involved in a local
archaeological dig over the past summer. We have many pieces of
stoneware crockery from the mid 1800's that I would like to re-assemble.
For historical integrity, we will not be trying to hide joints or paint
in-fillings. My question is the best adhesive to use. While your
tutorial seems to feel epoxies are best, I have also had recommended to
me the use of PVA white glues. Which is most appropriate for the repairs
I intend?
Thanks.

Hi Clarabella, a good question! We first create the texture on a flat clay as you may see in the tutorials shown in the links below. Once the texture is applied, we then cut the clay to the appropriate size / shape and assemble to whatever the final product is.

Hi, I actually want to ask a question rather than give input.
I saw at a handmade gift shop clay ornaments like hearts, that had imprinted on them patterns of material. One could clearly see the material fibers imprinted on the clay. It was beautiful. I asked the shop assistant about it, but she didn't really give me an useful answer about how the item had been made. She just said something about the clay being 'buffed'.
I would like to ask you (the clay experts :-)) how did the artist do the imprinting on the clay and what does’ buffing clay' mean?
I make home made bread and cold porcelain clay but I don't know anything about working with these types of clay.
Your input would be very appreciated! Sending regards from South Africa!

Morty and Patty,
Wow! Thank you for the prompt and thoughtful reply! The thing I most love about the internet is communicating, like this, with experts I would never have had a chance to talk with in an earlier time. I am 72 (but don't look or act it!) and discovered pottery about three years ago. I fell in love with it at the first turn of the wheel, and I think I can say that I have now become an intermediate potter, after many hours of playing in my cellar studio.
I give my pots as gifts or donate them to charity silent auctions, and I'm hurrying to get my last batch bisqued and glazed and boxed up to mail to relatives for Christmas. Thus my question about speeding up the final drying.
At the moment my last two round lidded pots with texture from my new Steve tool are in my kitchen oven, set at about 180. Everything else is bone dry and in the kiln (in my garage), waiting for these final 2 pieces. I won't be able to start on the glazing until Monday noon, because of several events I must attend, so I do have time for a long pre-heat setting. I sure don't want these 2 nifty pots to explode!
Thanks and happy holidays, from

Hi Ginny, very good point and further clarification is needed in the write up - thank you for your questions and the expanded explanation will be incorporated for others to benefit from.
Let's first define "damp" - Damp is referred to when the clay is almost dry but has slight signs of wetness. At this stage, most of the drying shrinkage has occurred and the clay does not have much remaining movement. Thus, it makes it relatively safe to expedite completion of the last bit of drying. The only exceptions are large forms, in particular flat forms, and pots with walls that are thicker than 1/2".
Generally, when candling in a computerized kiln going from ambient room temperature to 180 degree F, the temperature rise is slow and it takes approximately 2 hours to get there allowing the last minimal shrinkage and evaporation of the remaining water to occur gradually and slowly.
If the damp pots are placed in the kiln room when the room is not too hot and the kiln room temperature rise is slow, it will have a similar beneficial effect as candling. However, if you place damp pots in the kiln room when the room is already hot, the rapid temperature change will cause rapid drying and shrinkage which can place your pots at risk of cracking. Kindly, Morty and Patty

Can both of your statements above be true?
"If your pieces are not completely dry and you have damp clay, you may want to candle them first."
BUT YOU ALSO SAY:
"Do not store greenware that is not completely dried in kiln room while kiln is operating or room is above normal room temperature - pots will dry too fast and will crack or create stress on the pots which will more likely crack in the firing."
SO, can I safely hasten the drying of a piece for a bisque firing by leaving it in the oven at 180 overnight? It's not bone dry yet, but I want to add it to this load.

Hi there, thank you so much for getting back to me. I hope to experiment with some of these glazes in the coming months. Wish me luck. :)
Thanks for your time,
Ben Greiling
---------------------------
Hi Ben, we do not "cookie cut" water measurement / glaze powder ratio. The ratio you mentioned is probably an average ratio. Every glaze can vary with water quantity based on the ingredients and the desired effect.
We use the "finger test" where we look for how fast the first drop or two drips off your finger. With an average glaze, the first drop falls quickly and the second one falls more slowly while the third one just stays hanging for a while.
Thin - first two drops fall relatively quick
Thicker - first drop falls off slowly
When you sieve it, leave the glaze on the thick side (yogurt like consistency) and add water as needed later.
- Zam Celadon needs to be on the thick side otherwise it settles
- Clear blue on the thin side but can also be thicker for different transparency affects. Clear blue can start smell bad after a couple of month - it is normal.
- Olive Green can be thin, thick or average. When thick, blue starts showing but be careful about running onto the kiln shelf. When average, it is does what it was designed to do - Olive green color. When thin, a nice browns start showing up.
-The others on your list are average thickness.
Note: With the Olive Green and Peggy's Blue, the glaze gets thicker a few hours later - do the "thickness" test the next day.
As with any new glaze, run some test tiles before glazing your hard labored pots.
Good luck, Patty and Morty

Hi There,
I was wondering how much water should be added to your cone 6 glazes? Some other glazes I have used call for 1 quart for 1 lb of dry glaze. Would this work? Or do you kinda need to go by the consistency of the liquid. The glazes I am targeting are Zam Celadon, Matte Black, 2-D Blue, Peggy's Blue, Clear Blue, and Olive Green Caledon. Let me know the best way to make these glazes. Thanks so much. Happy throwing!

Hi Jennifer, thank you for your note and glad you found our web site to be useful.
The clay we use is a buff cone 6 clay made by standard - Baldwin 192. See link below for all of our glazes and if you choose cone 6 (more functional and durable), pay close attention to the write up at the bottom of the page about using underglazes with cone 6. Most underglazes / clear glaze fail at this temperature and we "weeded out" the good from the bad for whomever decides to use our path (doing so for almost 10 years successfully).

Hi Adrien, Opulence 508 Goldenrod will give you very similar results. It does not run. For the yellow you see in the picture you have sent, dip it twice. Make sure glaze is not mixed too thin so avoid settling. Good luck, Patty and Morty

Hello,
I observed a wonderful looking yellow glaze "Golden Rod" (see below) on your website and noticed that the recipe was "...not published at this time." Does that mean it may get published in the future? Or is it a commercial glaze? I have been looking for a nice (oxidation fire) yellow glaze recipe and this one seems to be right up my alley. Please let me know if the recipe is or will be available. Thank you for your time.

Hi Cynthia, either epoxy mentioned in our web tutorial will yield the same end results assuming the timing is not an issue. Make sure that the epoxy strength is 2000 lbs or greater. Note that you will see the seam line if your effort will end at gluing. Good luck, Patty and Morty

Hello, I had a shelf in my living room fall and four Indian pottery figurines were damaged. the pieces are fairly large so I thought I'd try DIY. Which epoxy do you recommend for American Indian pottery? They only have the quick dry one at the hardware store and I'd like a little more time to work the pieces into place.

Hi Rob, Perhaps you want try it without adding anything. Make sure you let it dry very slowly and use plaster, masonite or wooden bat (in that order of effectiveness). Sieving with a mesh 60 will be sufficient and easier to push the soft clay / slip through. Not that slip should not be too thick and it if it cracks in places, it will do so in low peeks (valleys) which it is easier to fix using a rubber tip tool when the slip is starting to get leather hard. To fill in gaps or cracks, dry some of the slip to leather hard before applying to cracks (if any).
-----------------------------------------
Hello,
I am a potter and was thinking of making slip with my clay in the way that you mentioned on your website. (basically mixing well, and sieving to remove grog, apply to leather hard pot).
I was wondering if a deflocculant needs to be added so that the slip does not crack on high peaks?
I will try making slip in the way you mentioned, and sieve in an 80 mesh screen. Hopefully it will work with this screen. The clay body is a fine dark throwing body with LOTS of iron and manganese. any help appreciated. Thanks, Rob
PS I love your website! Thanks for sharing such great info....

I am really pleased about the number of links in addition to the great content available on http://lakesidepottery.com/Pages/usfulllinks.html. At this point, I am keen on teaching my daughters some craft work and thought of pottery. I spent hours online looking for a good resource until I discovered your website. It was a breeze going through your page - you really did a good job here. Such a big help for a busy single dad like me. Now your site is just a click away from my bookmark.
Oh and by the way I did find the following broken links on your website. I thought you might want to replace them with new ones:

I am hoping that you continue to maintain your page and as a simple token of my gratitude, I'd like to give you an educational website that I know would be a very good addition to your list. I also use http://www.startlocal.com.au/articles/educational_pottery.html as reference; it is also good source of information on pottery such as its history, basic process, and the industry. That page also has a link to your site, that’s how I found your page.
I hope I was able to help you in some way because you surely did help me by making my job easier. Love to know if you found my suggestions helpful.
Cheers, Jacob 'Coby' Crane

Right! Make sure you have a long wire a head of time and run it soon after you thrown the pot. The wire should not be too thin to make sure a good separation (clay from bat). A thick guitar string will do a good job. Ask for help when running the wire. It is hard to see if the wire is lined up ok with such a big platter. Another option is to use a plaster bat which will eliminate running the wire step. However, large plaster bats are very expensive and very heavy (flipping over is a bear). Let us know how it worked out.
------------------------------------------
Hi Lakeside, thanks for the tip. I assume the pot releases from the wood bat the same as if it were on a plaster bat, right? June
-----------------------------------------
Hi June, you make a large coil and place it on the inside of the platter. The coil need to be higher than the platter's highest point. You then place a large bat on top of the coil. So your "sandwich" from top to bottom is with 1) Large bat, 2) large coil, 3) your leather hard platter and 4) large bat. You (if very strong) or with another person, flip the "sandwich" upside down and you are ready for trimming.

Hi Benjamin, for the blue effect: thickness like slightly thin yogurt / thin jell. I suggest you make some test tiles and determine yourself. Very hard to describe accurately in particular when the glaze feels thinner or thicker before and after mixing. For the test tiles, mix the glaze normally, and make tile 1 - one dip, tile two - two dips (wait only 2 seconds between dips). Note that when applied thick, the glaze moves and you have to be careful with enough clearance on the bottom of your pot.

Hi. I am interested in the beautiful olive glaze recipe you have. You stated that applied thicker gives bluish tones, like on the fish. How exactly can you describe the "thicker" part. Normally, a glaze has a certain floury/milky feel when dipping into it. Would thicker be more of a pancake batter consistency? In other words, how thin should it be to get the green?

Thank you - very informative. I am a new potter and my husband purchased me a Skutt with kiln sitter.
I am still unsure of what to bisque fire to and glaze to. My first fire with glaze didn’t turn out well - Clear over glaze was cloudy and my dipped glazes turned out dry and powdery and another pieces the colors looked over baked and not the color they were dipped in. My pieces were bisqued at my class to cone? and my over glaze was cone6 and I fired to cone 05.
Have lots of questions -
thanks for you help

Thank you so much for publishing these glazes. I am a teacher at Vicksburg High School in Vicksburg, MS. We have discussed mixing our own glazes and when I did a search for cone 6 recipes, your site was the first to pop up. The glazes are beautiful. I also just made a bunch of tiny tests of my underglazes to see if they would hold up at cone 6. I haven’t fired them yet, but I was thrilled with your addendum on underglazes. If you publish more of the recipes that are not available to the public at this time, please send out a note!

Good day, I just read and viewed all of Isaac's videos and I must say that he was a true artist at heart and I wonder why a country as great and beautiful as Britain would let such history (buildings and installations) go to waste... surely there must be a way to gather money to renovate the buildings to their original state and have Isaac's memory and his work be revived and he a tourist attraction... there is an enormous potential for sightseeing and seeing potters in action in the original buildings... think of the potential...
By the way, I live in Canada and am in the process of setting up a studio in my home basement... and am quite anxious to start potting again in my studio I've dreamed of having for years...Cheers

I have a Paragon 7 kiln and can fire up to 1700. I do glass slumping, fusing and beadwork as well as traditional stained glass (both lead came and foil).
Way, WAY back in high school I spent a couple of years doing ceramics at a ceramics studio and liked it very much. No throwing of pottery however. I am familiar with glass (coe etc), underglazes and glaze.
As I said before, I had purchased a set of clay (I believe clay base) tiles a couple of years ago with what looks like a couple of different glazes (tan and dark brown in areas on the top with the VERY same cracked glass look featured on your page below. At the same place the artist also had large plates, bowls and platters done with the same technique. This was out of state when I was on vacation.
I have been trying to find information on how to achieve this look and until finding your site I have had no luck. I am pretty confident that by applying crushed glass or frit over the proper glazes with the proper temperature I could get the look I am trying to achieve-I don't know what the propers are though. It truly is quite the same as your turquoise and yellow samples on the left side of the page on your site.
My problem is that I wonder #1. Do I have to make my own tiles out of clay and what kind of clay to use if I do, #2 What glazes to use and then what temperature all needs to be fired at. Like I said, I can only go to 1700 degrees in my kiln. Can a premade bisque tile be used (not kiln washed?) Can a premade already glazed store ceramic tile be used? Just not sure where to go from here.
Any insight you can give would be greatly appreciated. Thanks, Sue

Answer: Hi Rob, Perhaps you want try it without adding anything. Make sure you let it dry very slowly and use plaster, masonite or wooden bat (in that order of effectiveness). Sieving with a mesh 60 will be sufficient and easier to push the soft clay / slip through. Not that slip should not be too thick and it if it cracks in places, it will do so in low peeks (valleys) which it is easier to fix using a rubber tip tool when the slip is starting to get leather hard. To fill in gaps or cracks, dry some of the slip to leather hard before applying to cracks (if any). Kindly, Patty and Morty

Reference Tip: Mixing and using glazes
Reference Picture
I found your site on the Internet and it's awesome!
I have a question that I couldn't find, and hope you can answer.
I have recently fired several pieces of pottery and when they came out of the kiln, the items had tons of pits in the glaze throughout the items. I am wondering if you have any idea what causes this? Attached is a picture of the bad glaze or bad peppers as I have it saved. Thanks for taking the time to look at it, much appreciated. Many thanks!
Answer: Hi Eydie, what you are experiencing is called blistering or craters. It results from glaze bobbling and cooling off in bubbling midstream.
Bubbling causes:
1) Glaze / clay combo incompatibilities
2) Kiln gases are not properly vented during the glaze firing process (pots are too close to wall or each other, using a whole kiln shelf instead of two halves, no air flow (e.g., no kiln vent).
3) Lack of oxygen
4) Borax, potassium carbonate, soda ash, magnesium sulfate, fluorine and magnesium sulfate can produce large amounts of out-gassing
Possible fixes:
1) Change clay body
2) Increase air movement (more oxygen) and exit of containments from the kiln. EnviroVent is the best way to achieve it.
3) Increase holdup time at end firing cycle enabling the bubbles to melt / settle properly before cooling starts.
4) Increase temperature slightly to get passed this specific glaze bubbling / boiling stage
5) Reduce temperature slightly to stop firing below this specific glaze bubbling / boiling stage
6) Apply the glaze a bit thinner (blisters settle faster and more effectively)
7) Do not use this glaze
Through our experiences, the action we take with any glaze the exhibit blistering / craters and requires special treatment, we learned that the problem will repeat itself and therefore we take it our of circulation. Unless, proper venting solves the problem. Through the years, a couple of time the vent failed during firing and some pots exhibited your mentioned problem.
Good luck and please let us know if any of the above fixed the problem

Reference tip: Pottery consulting and custom made Tagin
Some local Moroccan restaurant asked me if I cam make tagines for them with their logo. I feel reluctant getting into it, event though I think it will be fun, primarily not knowing much about flameware (what kind of clay to use, firing temperature, glaze) that will be used on direct flame or stove top. All the Tagine's manufacturers warn of cracking when extreme temperature differences occur (in heating or cooling). Do you know of a good clay body for the above application and what firing range. Note that when I tap on the Tagine the restaurant uses today with my wedding band, it sounded like an earthware (hollow and lower frequency).
Answer: Here are some recommendation for your Tagines project. You will need low fire red clay with grog. By extra 48/f grog so you can wedge more into the clay. Try to get a much extra grog into the clay as possible without making the clay too short and unplastic. When you throw the form keep the cross sections as uniform in thickness as possible. For this size project 3/8" or below a 1/2" cross section is best. Bisque fire the pieces to c/010. You can then use a food safe clear transparent glaze on the ware and glaze fire to c/06 but no higher. You can also use this glaze formula for a clear glaze.
- Ferro frit # 3195 95
- EPK 5
- Bentonite 2
The ware should be open enough to dissipate thermal shock when heated directly however, as you know this is a tricky thing. Firing the glaze at c/010 will improve the thermal shock properties but you loose some fired strength. You might have to test both firing options out in any case. I think the real trick is to get as much grog in the ware and still have it throwable.

Can one paint the base of a pot with underglaze or will it stick to kiln shelf when taken to glaze temperature (1300 degrees Celsius)?
Answer: Yes, you could with following conditions: 1) Test the underglazes and make sure it is not shiny (about half of underglazes have some silica components in it). Stains will be safer (e.g., Mason's stains). 2) Apply kiln wash on the kiln shelf. Good luck!

Thank you so much for supplying the watercolor green recipe: I've been hunting for a green to put on to SCM. Kind regards from Bornholm Denmark
Answer: Hi Lauge, There are some concerns you need to know when applying water color green over SCM. If you fire it cone 6 electric, too much Water Color Green over CMS will generate some blisters. Therefore, we found that spraying it will yield best results. Do some test tiles first
Reply: uh wow, thank you, I was actually contemplating doing cone 9 reduction. I thought I couldn't get the turquoise out without reduction? I will spray it though, thanks. Kind regards from the now extremely rainy Baltic sea

Hi Morty and Patty, I found your web-site and appreciate all of the info. Including the link to where you get your glass. I have experimented with the glass beads you buy for flower arrangements and the results were beautiful. But…. Sometimes there are popped bubbles in the glass. I will have one piece right next to the other—one is perfect, the other bubbled. The pieces were practically exactly the same. Do you ever have this problem with the glass from your recommended supplier? Do you do something to prevent this from happening, such as a hold at the end of the firing. I to fire at cone 6 with a computerized kiln.
Also, what size of glass do you buy? Any other suggestions to get red? So appreciate the help.
Answer: We are glad you found our site useful. Thank you for the comments.
Some times we get bubbles when we place too much glass. We also saw bubbles years ago when we started to experiment with glass until we settled with the glass supplier we mention in our tutorial (see link below). When you go to the tutorial page, you'll see that we added the part numbers for the glass we are using for years now. Different glasses have different melting temperature which might be the cause of the bubbles you see (requires more than cone 6 perhaps). We use a hold up time of 15 minutes (cone 6). As far as getting red, create a test tile using the red glass we recommend with your different glazes. The results will vary and will help you to narrow down the red you want to see.

What type of glass do you get from the American specialty glass? I would like to try the glass in a couple of my pieces. I would assume you put the glass in after you bisque
Answer: Hi Linda, below is the list of glass we use for ASG and yes, we place the glass on bisqued pots. Good luck, Patty and Morty
1) Turquoise S-533 #3 (by far the most used with the best and consistent results with all of our glazes)
2) Yellow S-161 #3 (second best with consistent results with all of our glazes)
3) DK Blue BN-301 #3
4) DK Purple S-142 #3
5) DK Green S-123 #3
6) Red S-151 #3
7) Champagne S-591.1 #3

I am new to the world of clay and found your website. You've been bookmarked and I continue to read with enthusiasm. I have a question regarding your "Firing, Melting and Fusing Glass on Pottery" section. I ordered some glass from the website you recommended (American Specialty Glass). I ordered some of their samples kits to play around with. They have a mirrored glass as one of the samples. Have you tried using mirror before? Would you recommend it? Are there any dangerous fumes from the mirrored surface? Please let me know when you get a chance. And again, thanks very much for putting together such a comprehensive and informative sight for a newbie to gain some insight. Best, Charles
Answer: Hi Charles, thank you for your note and we are glad you are using the information we posted on our web site. Modern mirrors is made out of regular glass and aluminum is the most commonly used as the metallic coating for the reflector. Some manufactures can use Chrome. If the kiln is vented properly, you should be ok firing it although I am not sure what will the metallic material effect will have mixing with glass and / or your glazes. Try it and you find a moment, share your findings with us. Kindly, Morty and Patty
Next reply: Hi, I wanted to take a moment to thank you for your earlier response and the recommendation of using ASG Glass for incorporating glass into glazing. While I haven't had the chance to use the mirrored glass yet, I did want to share my pics of the three recent things I've done with the glass. Thanks again so much for your website and creative ideas. All the best, Charles

Hi guys - I stumbled upon your website while searching for beautiful cone 6 oxidation glazes. I am excited to explore your information-filled site. I am a "reborn" newbie potter/sculptor (discovered it about 10 years ago, then was busy getting 2 girls just about into/though college). I have a used electric kiln that's never been fired by me in my shed, and several newly created sculptural pieces that need to be glazed. I am worried I will ruin them all at this stage, but hope tips I learn here (along with many test pieces) will help me get going. Thanks for this site.

I really enjoy the site and had a quick question about fusing glass on pottery. I see that you say because of the cracks in the glass, it is not food safe. I am wondering what would happen if I fired the piece once with the glaze and glass on it, then after the first firing re-glazed it with a clear glaze and fired it again? Would the clear top glaze stay on top of the glass, coating it and making it food safe, or would the glass melt again, the glaze mixing in with it and it still have cracks? Your input and experience is very much appreciated!
Answer: Hi Brittney, Re firing it with glaze will not hide / seal the cracks. The glass will melt again and will crack again. Glad you enjoyed our site, Patty and Morty

After using epoxy can you eat from the plate? Looking for a glue to repair and still be able to use the bowl to eat from. Any suggestions?
Answer: Hi Debbie, Epoxy has a lot of toxic materials in it and I would not eat from it. Generally, I will not eat from any ceramic type material unless it is glazed with a "shiny glaze" that was fired in a kiln properly. Thanks, Patty and Morty

My grandmother gave me a crock to make pickles in. It has a crack in it. Would the epoxy process still be ok to use since there will be food kept in it. Thanks !
Answer: Hi Daren, Thank you for your note. Glues have all sort of toxic material that can leach into food in particular when they have salt and acid in them. So unfortunately, once ceramic or any vessel that holds food is glued, it is not food safe.

Email: newdittbenner2000[at]yahoo.com
Have you tried the following glass and what was the results if so -marbles? Glass melted marbles you use for flower arrangements? Combination of clean recycled broken glass off the ground from a salvage yard from old windows and doors which includes everything from old leaded windows to car windows and newer window and hurricane glass? Soda, wine or beer bottles? Also, how do you achieve the look of stained glass that is see thru in the middle? If I use a glass mold to melt a glass bottle, can I use some unfired glazed pieces set in the middle safely or should I try to fire them first then drop them in when I try to melt the bottle - or will that even work? I am pretty new to working with clay and I would like to try this on my hand built pottery. It isn't my kiln so I don't want to end up damaging it. I am really excited to try new things and the glass sounds like so much fun! Your website is so inspiring!!! THANKS FOR YOUR KNOWLEDGE AND HELP!!!
Lynn
Answer: Hi Lynn, It is nice to see enthusiasm in reference to pottery. We tested many glasses type and they all work (cone 6) but give different results depending on the glass type and what glaze it is over. If you use too much glass one or all of the following could occur: 1) Glass bubbles 2) The thick glass tension can break the pot (depending on the pot structure and it's thickness (and leak all over the kiln shelf). Think of the glass as if it was ice. So if you use marble, it will melt and it's volume will distribute on the available surface just like water will. Any other variables (e.g., stain glass, bottles, etc., you will require a test tile (or a small test bowl) to see the results before you attempt it on your pot (might ruin your pot, the kiln shelf and possible other potter's work in the kiln. Thank you, Patty and Morty
