Glaze Material Substitutions This page provides a set of calculators to help with calculating common material substitutions in glaze recipes.
Warning: These calculators are based on theoretical UMF analysis of the materials, and I have not verified them experimentally. Oxide analysis isn’t the only factor that determines how a material will behave in a glaze.
Each calculator allows for conversions between two material forms. Click “Switch” to toggle the conversion direction.
