How Sgraffito is Created on Pottery
Sgraffito, from the Italian word “sgraffiare” meaning “to scratch,” is a traditional pottery decorating technique. The process involves applying layers of underglaze or colored slip to leather-hard clay, then scratching through the surface to expose the natural clay beneath. This reduction process allows potters to carve images, patterns, and textures, creating high-contrast designs. Sgraffito can be applied to functional pottery, tiles, or sculptural forms, and works beautifully for both simple and complex designs.
Below are three example projects at different difficulty levels:
- Basic Sgraffito Project - Ceramic Tile
- Simple Sgraffito Project - Mug
- Complex Sgraffito Project - Urns

Tools and Materials
|
Wire Stylus Tools for Sgraffito
We recommend fine-point wire styluses for clean, detailed carving. Kemper wire stylus Sgraffito tools are widely available online and through ceramic supply stores.
Mini Ribbon Sculpting Tools
Mini ribbon sculpturing tools are excellent for controlled line work and removing underglaze.

Clay: The clay should be at the leather-hard stage, firm enough to hold its shape under light pressure but not so dry that it cracks or resists carving. This stage provides the best surface for clean, sharp lines and prevents accidental gouging or smudging. For stronger contrast, we us Standard's clay 181 white stoneware

Rubber shaper for clean up

Leather hard clay (tile / coaster)

Transfer design to tracing paper and then use sharp pencil and trace design to clay. Tracing paper is flexible and able to withstand the wet clay and multiple tracings. If using black underglaze, we like Amaco V-370 or LUG-1 (V-370 has slightly better coverage). Both perform well up to cone 6 glaze firing.

1. Basic Sgraffito Project - Tile
|
Apply 2-3 coats of underglaze, apply additional coats in alternate directions, and wait to dry before starting the scratching-off process. The tools and the pressure you decide to use are dependant on the affect you wish to see on the clay. If looking for rougher surface texture, push the tool a bit harder and take more material using more pointy tools. Scratches can have uniform or random patterns. NOTE: Only use a soft dry brush to remove debris to avoid damaging the colored areas.

To refine your lines and keep the surface clean, use rubber shapers or wooden modeling tools to gently clear away burrs and rough edges. Once the carving is complete, thoroughly clean the surface with a dry brush to remove any loose debris before firing or glazing.

2. Simple Sgraffito Project - Mug
The cups below use a slightly different technique than above. Only the traced pattern is painted on and the outline and lines within the pattern are scratched off.

3. Advanced Sgraffito Project – Two Urns
This project shows how Sgraffito can be used on curved surfaces with detailed designs. Working on urns requires careful planning, steady carving, and attention to drying stages. The steps below illustrate how layered underglaze and precise line work create bold, intricate patterns that elevate a simple vessel into a refined decorative piece.
