Quick Answer: How To Fire Glaze Ceramics

The general process of glazing ceramics is by mixing your glazes, applying the glaze to bisque-ware, letting it dry, then finally loading it into the kiln for the glaze firing.

Why do we bisque fire before glazing?

At what stage do you apply underglaze?

Painting with underglaze on pottery can be done either during the greenware phase, or the bisque phase. Nikki Mizak chooses to do her underglaze painting on bisque fired clay and enjoys building up layers as you do in watercolor painting.
