Pottery & Ceramics API

Pottery and ceramics maths as an API, computed locally and deterministically — the shrinkage, glaze-batch and firing numbers a potter works out at the wheel and the kiln. The shrinkage endpoint handles the fact that clay shrinks from wet to bone-dry to fired: with a typical 12 % linear shrinkage a 100 mm rim fires down to 88 mm, and run in reverse it tells you to throw a piece larger to land on a target size — make it 100 mm wet to finish at 88 mm — and reports the volume shrinkage, which is the cube of the linear factor (about 32 %). The glaze endpoint scales a percentage recipe to a real batch: pass the ingredients as a name:percent list and a dry batch weight and it returns the grams of each, dividing by the recipe’s own percent sum so recipes that total over 100 % (a base 100 plus colorant and opacifier additions) still scale correctly, plus the water to add for dipping. The cone endpoint gives the approximate firing temperature for an Orton self-supporting cone at the standard 108 °F/hour ramp — cone 06 is about 1828 °F (998 °C) for bisque, cone 6 about 2232 °F (1222 °C) and cone 10 about 2345 °F (1285 °C) for stoneware — and reminds you that a cone measures heat-work, not just temperature. Everything is computed locally and deterministically, so it is instant and private. Ideal for ceramics, pottery-studio, maker and craft app developers, kiln-log and glaze-calculator tools, and studio-management software. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. For kiln-element power use a different API.
