Zinc borate is used in many industries and is sometimes promoted as a flux for ceramics. Originally it was distributed by Anzon in Laredo, TX and promoted as a wonder material to reduce body maturing temperatures. The developer, "Stoney" Jackson reported vitrified bodies at cone 06. While it is not widely used in ceramics today.

Typecodes Flux Source
Materials that source Na2O, K2O, Li2O, CaO, MgO and other fluxes but are not feldspars or frits. Remember that materials can be flux sources but also perform many other roles. For example, talc is a flux in high temperature glazes, but a matting agent in low temperatures ones. It can also be a flux, a filler and an expansion increaser in bodies.
