Also referred to as calcium magnesium carbonate or limestone.
Dolomite (CaMg(Co3)2 or CaCO3.MgCO3.) is a type of milled limestone that is a useful source of both calcium and magnesium. As such, dolomite may be used in a glaze that calls for both whiting (calcium carbonate) AND magnesium carbonate or talc, allowing the chemist to use just one powdered material instead of two.
Aside from talc, dolomite is the main source of magnesium oxide in high temperature glazes. Dolomite can be used as a high temperature flux and to promote crystal formations in glazes -- glazes that use this material often aim to achieve the well-known dolomite matte surface, which is a pleasant matte. On its own, dolomite has refractory properties, but when it is combined with oxides in glazes, it properly fuses.
