Calcium magnesium carbonate is a natural material that combines calcium and magnesium carbonates. Generally used as flux in high temperature glazes although in combination with other fluxes it can be effective down to 1060º C. Above 5% it begins to become opaque and will eventually produce a matt glaze.
