What is glaze made of ? Silica: The ingredient that makes the glaze turn into glass. It is found naturally in sand. Quartz is a form of pure silica. Silica melts at 3100 degrees! (Too hot for our kiln) Flux: Minerals that lower the melting point of the silica. This makes it easier for us to fire at a reasonable temperature.

What is glaze made of ? Alumina- Makes the glaze stable. Keeps the glaze sticky so it doesn’t run when it is melted. Water- The vehicle that makes powdered glaze easy to brush or dunk.
