A studio notebook for hobby potters: a glaze book with a batch calculator, a cone chart with temperature equivalents, firing schedules with a running timer, a kiln log and a wall of test-tile photos pinned to the recipe and cone they came from.

No. The app works offline and keeps everything on your device.

Open a recipe and type a batch size in the calculator (grams or ounces). Every ingredient, including additions, is recalculated.

Colorants and opacifiers are measured on top of the 100% base, the way most potters write recipes. The base must total 100% before a custom recipe can be saved.

Duplicate it, then edit the copy. The original stays as a reference.

Pick a schedule, choose a kiln, add shelf notes and start. The app follows each ramp and hold on its clock and shows where the kiln should be. It does not control your kiln.

Only inside the app on your device. They are not uploaded anywhere.
