Particle size distribution depends on the size that the product is milled to. Our standard sizes are -1mm and -65micron. We can mill to finer sixes. However, we found that the aforementioned sizes are the most sought after.

Minerals Limestone
Limestone forms by sedimentation, of coral and shells (biological limestone) or by the precipitation
Minerals Magnesite
A magnesium carbonate mineral. It is quarried in California, Washington, Austria, Russia, Manchuria,
Materials Dolomite
An inexpensive source of MgO and CaO for ceramic glazes, also a highly refractory material when fired in the absence of reactant fluxes.
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.
