Underglaze
All of our underglazes are Talc Free and are highly versatile.
They can be used for complete coverage or in a design, can be applied to clay or bisque and they have a broad firing range from cone 06 to cone 10.
Most underglazes darken and become more intense when fired to a cone 5-6 or cone 10.
It is always recommended that you test fire each color on your clay body.
Apply to clay or bisque and fires from cone 04 to cone 10.
