Kilnshrink is a pottery shrinkage and studio planning utility for ceramicists, pottery students, and teachers. Clay changes size during drying and firing; Kilnshrink helps you plan the wet dimensions, fired dimensions, capacity, clay weight, and batch notes before the work reaches the kiln.
Core tools:
- Reverse shrinkage: enter a finished target size and get the wet size to throw.
- Forward shrinkage: enter a wet size and estimate the fired size.
- Batch Board: plan repeatable sets with count, clay body, finished target, wet dimensions, tolerance band, clay reserve, shelf footprint, rough capacity, and copyable production notes.
- Volume Calculator: estimate fired capacity for mugs, bowls, cylinders, and rounded bowls in fl oz and mL.
- Test Bar: calculate measured shrinkage from fired test bars, including optional two-stage dry/fire shrinkage.
- Studio hub: cone reference, glaze recipe scaling, firing schedules, clay weight guide, and offline Studio Reference Pack.
- Clay library: built-in studio clay presets plus custom clay bodies.
- History: save local project calculations and notes.
- Unit support: inches with pottery-friendly fractions, plus centimeters.
Everything runs on device. Kilnshrink does not require an account, network connection, camera, microphone, location, contacts, or notifications. Saved projects, custom clay bodies, recipes, schedules, and preferences stay in local storage.
