Short answer

OpenGlaze is a glaze recipe calculator and management tool. It combines batch recipe records with chemistry calculations and experiment documentation so potters can reproduce what worked and understand what failed.

Why it matters

Many glaze notebooks separate recipe, chemistry, photo, firing schedule, and result. OpenGlaze keeps those pieces connected.

Private by default

The supported launch path is self-hosted SQLite with Docker volumes, so studio recipes stay under your control.

Computational, not magic

The optimizer uses chemistry calculations and ranked suggestions; kiln tests still confirm real-world results.

How OpenGlaze helps

Record the base recipe and firing context.

Scale the batch and review chemistry calculations.

Attach photos and compare results across test firings.

FAQ

Can OpenGlaze scale recipes?

Yes. OpenGlaze includes recipe and batch calculation surfaces for glaze testing workflows.

Can it store firing notes?

Yes. The app includes firing logs, experiment stages, and photo documentation.
