Alumina oxide, Al2O3, is a chemical compound of aluminium and oxygen, and is commonly called alumina. Essentially a refractory, it is responsible for the matteness or brilliance of glazes. However, too much alumina can cause a dry appearance. It prevents devitrification and adds strength. Alumina oxide is insoluble in water and has a high melting temperature of 3550° F. Because of this, alumina oxide can lend great strength to clays and glazes and is frequently used in the industrial ceramics industry.

Alumina oxide comes in powder form -- the alumina oxide that we carry here at The Ceramic Shop is very fine-grained (versus more granular versions that may be available elsewhere).

Additionally, please note that this alumina oxide is calcined - if you have a glaze or clay recipe calling for calcined alumina, this is the product you will use.
