Ash Glaze Triaxial Calculator
Choose or enter three ash glaze bases by weight. The page works out every tile in the triangle, the corner batches to mix, and the raw materials to weigh out.
Weights are dry grams. Each tile is a mix of the three corner glazes in proportion to its position, for example 3A-1B-1C when steps = 5.
These choices set which recipes appear in the three dropdowns below.
These corners come from different firing ranges (high fire and mid fire). One cone will under-fire or over-fire some of them, so choose corners from the same range if you can.
