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.
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.
