How to Sculpt and Replace a Missing Pottery Rim Segment Using Resin Casting and Kintsugi

Step-by-Step Guide to Repairing Missing Pottery Rim

How to Sculpt and Add Missing Pottery Segment This tutorial shows how we repair and replace a missing pottery rim segment using resin casting and sculpting techniques. We create a rubber mold from an intact part of the rim, then cast a resin replica to perfectly match the original shape.
After carefully trimming and attaching the new segment, we fill gaps and smooth the surface to blend the repair seamlessly.

Finally, you can choose between a seamless finish or an artistic Kintsugi repair, where gold lacquer highlights the join, turning the break into a beautiful feature.

This method is ideal for restoring ceramic, porcelain, and stoneware pieces, whether for everyday use or valued collectibles. Step-by-step photos and video guide you through each phase of the process.
