Calculate ingredient weights for a triaxial glaze blend across a grid of test tiles.
A triaxial blend is a structured way to test three ingredients — or three whole glazes — at once. Picture a triangle: each corner is 100% of one material, and the tiles in between are systematic mixes of all three. Instead of guessing at proportions, you map a whole region of glaze space in a single firing.
Enter the weight you want for each individual test tile, then the percentage of each of your three components. The calculator works out exactly how much of every material to weigh for each tile in the grid, plus the total amount of each component to prepare — so you don't run short halfway through mixing.
Triaxial testing turns glaze development into something repeatable. Because every tile's recipe is recorded, you can see how surface and colour shift as the proportions change, then reliably scale up the one you like. It's a favourite for exploring a new base when you don't have a chemical analysis to work from.
