•The secret to cool bodies and glazes is a lot of testing.
•The secret to know what to test is material and chemistry knowledge.
•The secret to learning from testing is documentation.

A material the way it would be if its crystal structure perfectly matches the unit-cell drawings you find in textbooks. In nature, materials are always contaminated to some degree. Calcium carbonate is never pure, feldspar never has an ideal 1:1:6 relationship between fluxes:alumina:silica, kaolin particles are never crystal-perfect, etc. Some materials are theoretical in physical properties but have no theoretical formula (e.g. ball clays) because they are a mix of many minerals and have a definition that can encompass a broad range of products. When learning ceramic chemistry students usually use theoretical materials (e.g. potash feldspar, kaolin). However when they begin working in the lab of a company they use the actual chemistry of real world materials.

Ceramic Materials Overview
The study of ceramic materials is at the center of all ceramic technology. While knowing the chemistry of materials gives you control of most of the fired properties of glazes, knowing the physical an...

Ceramic materials are employed in the ceramic industry to make glazes, stonewares, earthenwares, porcelains, engobes, refractories, structural products, etc. We study ceramic materials at the mineral, chemical and physical levels.
At first it might seem strange to define this, but it is not as ob...
