Zinc-Free Clear is a glossy transparent glaze that produces attractive high fire glossy effects at mid-range temperatures.
*Zinc can cause some pigments in slips and underglazes to shift in color, this clear glaze was formulated to prevent 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.
