GlazeBench

Build a glaze and watch the Unity Molecular Formula update as you type. Scale any batch to the gram. Log every firing so a good result is never a one-off.

GlazeBench is the studio notebook for potters who take glaze chemistry seriously — and still want an app that gets out of the way.

BUILD A RECIPE, SEE THE CHEMISTRY Add materials and set percentages. The Unity Molecular Formula — silica, alumina, the SiO₂:Al₂O₃ ratio, and your flux balance — recalculates instantly, with your recipe's position plotted on the Stull chart. No spreadsheet, no waiting.

CATCH PROBLEMS BEFORE THE KILN Plain-language warnings flag the things that ruin a firing: a glaze likely to run, an immature melt, a silica ratio headed for crazing, or ingredients that simply don't total 100%.

SCALE TO THE GRAM Enter any batch size and read every material weight in large, high-contrast numbers you can see from across the bench — because you're weighing with clay on your hands, not holding the phone.

NEVER LOSE A FIRING Record ramp and hold segments, the cone you fired to, a result photo, and what actually happened. Tie firings to the recipe so next time you know which batch worked and why.

SOURCED, VERSIONED DATA Every oxide analysis carries a source reference and a data version, visible in the app. When the database changes you can see what changed — and which version you fired with.

WORKS AT THE KILN The full material library ships on-device. No signal in the studio is not a problem.

A NOTE ON ACCURACY GlazeBench gives you guidance, not guarantees. Raw material analyses vary between suppliers and batches — always verify against your supplier's current data sheet, and always leach-test glazes intended for food surfaces.
