Surface Decoration (Pre-Bisque) · Sgraffito: Scratching Through Slip

Medium

Sgraffito design on a bowl exterior

Take your scratch skills to a real piece.

The task

  1. Coat a leather-hard bowl with contrasting slip (dark slip on light clay, or vice versa)
  2. When the timing is right, scratch a repeating pattern or botanical design around the exterior
  3. Clean burrs with a dry brush (never damp; it smears)
  4. Work under raking side light (shadows reveal your lines as you carve)

Design ideas

  • Repeating leaf shapes around the circumference
  • Geometric bands (triangles, chevrons)
  • A continuous vine wrapping the bowl
  • Abstract flowing lines

Quality markers

  • Consistent line depth throughout
  • No smeared edges
  • The design "reads" clearly from across a room
