The Final Bake: Glaze Firing · Loading a Glaze Kiln

Easy

Plan a glaze kiln load

Glaze loading is completely different from bisque loading. The golden rule: glazed surfaces must not touch anything.

The planning exercise

  1. Arrange your glazed pots on a table (outside the kiln)
  2. Check every piece: no glazed surface touches another piece, a shelf, or the kiln wall
  3. Leave at least 5 mm clearance between pieces (glaze can bubble and expand)
  4. Sketch your layout plan

Key differences from bisque

  • Pieces cannot touch (glaze fuses them together permanently)
  • Pieces cannot touch shelves where glazed (hence waxed feet)
  • Pieces should be placed where heat is appropriate for their glaze (top is hotter in most kilns)

Things to double-check

  • All feet are waxed and glaze-free
  • No drips on the bottom half that could run to the shelf
  • Kiln wash is fresh on all shelves (insurance against accidental drips)
