Stull Atlas is a tool for ceramic artists and glaze chemists. It lets you explore thousands of glaze recipes mapped onto a Stull chart - the standard coordinate system for understanding glaze chemistry through Unity Molecular Formula (UMF).

The original Stull chart - Chart 1 from Transactions of the American Ceramic Society, Vol. XIV (1912). Stull mapped test glazes by their SiO₂:Al₂O₃ molar ratio and identified the regions that predict surface quality.
If you really want to "get into the weeds" of glaze chemistry, the https://stullatlas.app tool, by Ryan Lack, takes Stull's insight and applies it to a modern dataset of real-world glazes, giving you an interactive map of the glaze chemistry landscape. The primary dataset comes from Glazy. It contains thousands of community-contributed recipes with calculated UMF values, cone temperatures, surface types, and firing atmospheres. Each point on the chart represents a real glaze recipe that someone has mixed, fired, and documented.
