Notes

April 2014: This material was made by Global Stone James River, but they do not have an internet presence and this material cannot found on google.

It was available in a wide range of particle sizes from 200 mesh to 3 micron for a variety of filler and extender applications such as rubber, plastics, paint, latex, fiberglass, carpet, upholstery, adhesives, asphalt roofing and many others.

This material is 58% CaCO₃ and 41% MgCO₃.

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.
