Please note that glaze materials vary from one country to another and that all glazes need to be tested. Feldspars suitable for most of the glazes below are: Kingman Feldspar, Custer Feldspar (has 3% more SiO₂) (Potash) and Kona F-4 (Soda).

Glaze components may not always add up to 100% due to modifications. If you are having trouble finding frits, please consult the Frits Substitution Chart or the Materials Analysis Page at The Matrix Glaze Calculation Software page.
