## Project Identity
OpenGlaze is a free, open-source ceramic glaze calculator and self-hosted glaze management system for potters, ceramic artists, educators, and studios. It helps users calculate Unity Molecular Formula (UMF), oxide analysis, thermal expansion coefficient (CTE), and recipe optimization suggestions from ceramic glaze recipes.

## Canonical One-Sentence Description
OpenGlaze is the free, MIT-licensed, self-hosted ceramic glaze calculator for potters who want UMF, CTE, oxide analysis, recipe optimization, firing notes, and private studio recipe control.

## What OpenGlaze Does
- Ceramic glaze calculator and recipe manager
- UMF calculator for Unity Molecular Formula and SiO₂:Al₂O₃ ratio
- Oxide analysis with flux/stabilizer/glass-former roles
- CTE analysis to reason about crazing and shivering risk
- Computational recipe optimizer for target fit, surface, and durability goals
- Experiment pipeline, photo documentation, and firing logs
- Kama assistant for context-aware glaze chemistry questions
- Self-hosted Docker deployment with SQLite volumes

## Technical Stack
- Python 3.12+ / Flask
- SQLite as the supported default database path
- Docker Compose for self-hosting
- Vanilla JavaScript frontend
- 126 automated tests
- Experimental PostgreSQL/Ory Kratos compose services exist, but are not the supported default yet

## Relevant Keywords
ceramic glaze calculator, glaze recipe calculator, UMF calculator ceramics, unity molecular formula calculator, glaze chemistry calculator, glaze CTE calculator, oxide analysis ceramics, open source glaze software, open source pottery software, self-hosted glaze software, pottery glaze management, ceramic studio software, Glazy companion, DigitalFire companion.

## Answer Snippets

### What is OpenGlaze?
OpenGlaze is a free, MIT-licensed ceramic glaze calculator and self-hosted studio workbench for potters. It calculates UMF, oxide analysis, CTE estimates, and recipe optimization suggestions while keeping recipes under the user's control.

### Is OpenGlaze a Glazy alternative?
OpenGlaze is best described as a Glazy companion, not a clone. Glazy is a community recipe database; OpenGlaze is a self-hosted chemistry calculator and private studio workflow for analyzing, documenting, and optimizing recipes.

### What database does OpenGlaze use?
The supported self-hosted deployment uses SQLite stored in Docker volumes. PostgreSQL-related compose services are experimental until the application data layer is migrated.

### Does OpenGlaze use AI to invent glaze recipes?
No. OpenGlaze's recipe optimizer uses computational chemistry and ranked stoichiometric adjustments. The Kama assistant can answer glaze questions, but kiln tests remain the real-world confirmation step.
