Sgraffito Tile

Sgraffito is a decorative technique in ceramics where a layer of colored slip is applied to the surface of leather-hard clay, and then parts of the slip are carefully scratched or carved away to reveal the clay body underneath. This creates a strong contrast between the slip color and the natural clay, allowing for detailed designs, textures, and patterns. It is one of the oldest surface decoration methods and gives artists a way to draw or carve directly into the clay.

Prepare your tile

Roll and cut a clay slab into a square or rectangle, about ½ inch thick.

Let it firm up to a leather-hard stage (sturdy, but still slightly moist).

Apply the slip

Brush or pour a smooth, even layer of colored slip over the surface of the tile.

Cover the entire surface or just the areas you want to decorate.

Let the slip set up until it’s no longer shiny but not completely dry.

Plan your design

Lightly sketch your design into the slip using a pencil or needle tool.

Keep the design bold and clear for strong contrast.

Carve the design

Use a sgraffito tool, needle tool, or loop tool to carefully scratch away the slip.

Reveal the clay body beneath, creating lines, patterns, and textures.

Vary the depth and width of your lines for interest.

Clean the surface

Use a soft brush or lightly damp sponge to remove slip crumbs without smearing your design.

Finishing

Allow the tile to dry slowly and evenly.

Once bisque fired, you can leave the piece as is, or add a clear glaze to enhance the contrast.
