Alumina, often derived from clay, stiffens the molten glaze to prevent it from running off the piece.
What makes a glaze?
Glazes consist of silica, fluxes and aluminum oxide. Silica is the structural material for the glaze and if you heat it high enough it can turn to glass. Its melting temperature is too high for ceramic kilns, so silica is combined with fluxes, substances that prevent oxidation, to lower the melting point.
