Zinc-Free Clear* is a glossy transparent glaze formulated for use with a wide range of underglazes and engobes.
*Zinc can cause some pigments in slips and underglazes to shift in color, this clear glaze formula prevents those color shifts.
**Note that all dry dipping glazes can be difficult to layer. Dipping glazes behave differently from brushing and they require thorough testing prior to layering full piece.
Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination.
