How is ceramic glaze made?
Raw materials of ceramic glazes generally include silica, which will be the main glass former. Various metal oxides, such as sodium, potassium, and calcium, act as flux and therefore lower the melting temperature. Alumina, often derived from clay, stiffens the molten glaze to prevent it from running off the piece.
Why is lead used in ceramic glazes?
The glaze – which may contain lead to facilitate the melting of glaze particles – fuses to the pottery when it is fired in a kiln, a special oven used to bake clay.Because the lead may not fuse into the non-lead glaze, it may contaminate food when the pottery is used with food.

Can you match a specific color for the glaze on the mugs I am ordering?
