Every test tile keeps its number, from the glaze bucket to the kiln shelf.
Glazimo numbers a test series for you, plans it as a grid of coats if you like, records the clay, the layers in the order you applied them and the firing, and ties the photos you take after the kiln to the same tile. Then it shows which tiles differ in exactly one variable, so a result is something you can explain and repeat.
Free to start: your whole first test series, with every export.


From numbered tiles to a comparison you can explain.
The whole job of a test series in one place: plan it, record it, fire it, photograph it, compare it and print it.
A numbered test series
Create twelve tiles, or up to 99, and write the label on the back: 3-07 is series 3, tile 7. Sort by glaze or by missing variables whenever you like; the labels do not move.
A grid of coats, planned for you
Pick one or two glazes and a range of coats. Every combination becomes its own tile with its own label, and the series opens as a matrix: what is the same on every tile at the top, one glaze down the side, the other across. Tap a cell to set its coats and method, or to compare along its row or column.
Clay, layers and firing, tile by tile
Record the clay body, each layer in application order with its number of coats and how you applied it, and the firing: your kiln log name, the cone and the atmosphere. Walk the series tile by tile with large buttons, copy the layers of the tile before, and let every change save itself. The library names the next step for the series you are working on.
Photos on the right tile
After the firing, run a photo round: the label of the tile that is up stays large on screen, the photo goes to that tile and the round moves on. Or add photos from your library through the system photo picker, which never asks for access to your photo library.
Comparison that names the difference
Pick a tile and see the tiles fired on the same clay and at the same cone and atmosphere, with the one thing that differs spelled out: Layer 1 coats: 2 → 3. A tile where a value was never recorded is marked as not comparable instead of pretending. Two tiles side by side line up every recorded value, with the one that differs in copper.
Make it again
Mark a tile you want to repeat. It stays on the shelf at the top of your library, and a new series started from it takes over its clay, firing and layers, with new labels.
Print, export and move
Print a test sheet or cut-out labels on A4 or Letter at full size, export a CSV with one row per tile, or save an archive with every photo that opens on another iPhone, iPad or Android device.

Questions potters ask first.
Does Glazimo measure glaze colour from my photos?
No. Colour in a photo depends on the camera and the light, so Glazimo shows photos for looking and compares the recorded variables instead. Put the fired tiles side by side in the same light.
What happens to label 1-07 if I delete tile 1-06?
Nothing. Labels come from a counter that only goes up, so 1-07 stays 1-07 and 1-06 is never handed to a new tile.
Does it tell me whether a glaze is food safe?
No. Glazimo records what you did and what you saw. It does not derive chemistry, temperatures or safety claims from your records.
Can I move my tests between an iPhone and an Android tablet?
Yes. Export an archive (.glazimo) with every photo and import it on the other device. Glazimo checks the whole archive before it changes anything, and names any photo it could not read.
Where is my data?
On your device. There is no account, no cloud service and no upload. Exports go where you send them.
How Glazimo is made
We develop our apps with AI tools for programming and translation. We use automated checks and device tests. oomny is responsible for the result, and a person answers support requests.
AI and data processing in this app
The app itself contains no AI and does its work on your device. The line illustrations on its empty and photo screens were made with an image model and are marked as generated; the tile photos in our screenshots are generated demo images too.
