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.
How do you test for lead in ceramics?
Lead-containing glazes or decorations on the outside of dishes or non-food surfaces are generally safer to use. The only way to determine if certain crockery has lead is to test it. Home test kits can tell you if the dishes have leachable lead. These tests are most useful in detecting high levels of lead.

How hard is ceramic?
Ceramic materials are brittle, hard, strong in compression, and weak in shearing and tension. Ceramics generally can withstand very high temperatures, ranging from 1,000 °C to 1,600 °C (1,800 °F to 3,000 °F). Glass is often not considered a ceramic because of its amorphous (noncrystalline) character.

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