Sodium Fluosilicate

Alternate Names: Sodium Silcofluoride

This material has a complex reaction during firing similar to Cryolite. Since it gains weight on firing its analysis totals more than 100.

Materials	Cryolite
Materials	Fluorspar
Oxides	F - Fluorine
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.
