Gillespie Borate is a sodium-calcium-borate compound used as a flux in ceramics. Gillespie Borate is a replacement for Gerstley Borate which is a common ingredient in glazes for all firing temperatures. It is essentially a way to introduce boron into glazes and acts as a melting agent. It also helps to prevent crazing.
