Slip can be manipulated with combs, stamps, or other textured tools for tactile surfaces. Carving through a slip or engobe layer to reveal the underlying clay, known as sgraffito, offers striking contrast and detail. Let each layer dry appropriately to avoid smudging or cracking.

Checklist for Successful Slip and Engobe Decoration
