    Ball mills can be used to further break down or refine a single material or you can place multiple materials into a ball mill jar to mix as you pulverize -- this is a very common industrial solution for mixing glazes that require the smallest of mesh sizes. Ball mills basically function like a mortar and pestle but on a much larger scale.
