Make your own
Make your own: This is the most advanced form of glazing. Using recipes, you buy raw materials and mix them. In addition to the other things, you will need recipes, which may be obtained from many books and web site. You also need the chemical, which make up your glaze, a scale, a sieve, and a temprement which allows experimentation. Sometimes your glazes won't turn out quite right. You will have to learn how to modify those glazes to solve whatever problem you're having. Other times they will be stunning.

Bone ash: Description
Bone ash is ground bones, usually cattle bones. It is one source of calcium phosphate; others are phosphorite and apatite. It is used as a flux in bodies where the calcium oxide does the fluxing and the phosphorus oxide acts as a glass-former in the melt and also checks over-rapid fusion. Its stiff glassy character is seen combined with that of feldspar in bone china. Bone china contains 45 – 50% of bone ash. A small amount of carbon remains in bone ash when calcination is controlled and this carbon assists the raw plasticity of the body.
