Keep every glaze batch within reach
A local-first recipe journal built for studio potters. Log oxide proportions, firing conditions, and surface results. Compare variants. Never forget which copper percentage gave you that exact turquoise.

Compare batches
Pick two batches to see their oxide proportions, firing setup, and results side by side. Useful for tracking how a small tweak changed the outcome.
How to use this tracker
- Create a recipe. Give it a clear name like "Shino v2, more soda ash". Fill in your base glaze and oxide additions.
- Fire a test tile. Always test on a small tile before loading a full kiln. Note the cone, atmosphere, and soak time.
- Log the batch result. Open the recipe, click "Log batch", and record what you see. Color, texture, fit, crawling, running, anything.
- Tweak and repeat. Use "Log batch" again for the next variant. Over time you build a history of what works.
- Compare. Use the Compare tab to put two batches next to each other. Spot the difference that mattered.
Common mistakes
- Skipping the batch log. Writing down the recipe is only half the job. The result is what you need next time.
- Vague notes. "Looks good" does not help in six months. Write "satin matte, no crawling, fits stoneware body A".
- Forgetting the clay body. The same glaze behaves differently on porcelain and dark stoneware. Always note the body.
- Not retesting. Materials change between bags. A recipe that worked last year may shift. The tracker flags entries older than six months.
- Ignoring application thickness. Thin and thick coats of the same glaze can look like two different recipes. Note your dipping time or spray passes.
Assumptions and limits
All data lives in your browser through localStorage. Nothing leaves your device. If you clear your browser data, your recipes go with it. Export important entries as a backup.
The tracker does not validate glaze chemistry. It stores what you enter. Always run a stability test (leach test) on food-safe glazes before using them on functional ware.
Oxide percentages are by weight of the dry batch. If you work with a different system, note that in the recipe notes.
Troubleshooting
- My recipes disappeared.
- Check if you are in a private browsing window or if site data was cleared. Re-import from a recent export file.
- The comparison table looks empty.
- Make sure both selected batches have at least one logged result. Batches without results show only the recipe header.
- I need to share a recipe with a friend.
- Open the recipe, click Export, and send the .txt file. They can copy the values into their own tracker.
- Can I use this on my phone in the studio?
- Yes. The layout adjusts for smaller screens and works offline once the page has loaded.
