Our Mission
Pottery is a delicate balance of art, physics, and chemistry. When clay dries and fires in the kiln, physical shrinkage, density changes, and thermal expansion take place. Managing clay shrinkage, plaster batch ratios, glaze specific gravity, and firing costs shouldn't require complex spreadsheet math or guesswork in the middle of a throwing session.
Clay Tools was built to give potters clean, fast, and mathematically rigorous tools right on their workshop benches or smartphones.
What We Build
- Printable Clay Shrinkage Rulers: Standard and custom vector PDF/SVG rulers pre-scaled to offset clay shrinkage during wheel throwing and slab building.
- Clay Shrinkage & Dimensional Calculators: Bidirectional tools to calculate wet-to-fired dimensions, fired-to-wet target sizes, and multi-axis differential shrinkage.
- Studio & Glaze Utilities: Plaster water-to-plaster mix ratio tools, glaze rescaling calculators, specific gravity adjustment calculators, and Orton pyrometric cone reference charts.
- Business & Studio Operations: Pottery pricing, break-even cost analysis, kiln electricity firing cost estimators, and printable studio logs.
Privacy & Client-Side Design
We respect studio privacy. All calculation tools run entirely in your local web browser. Your clay recipe numbers, measurements, and pricing preferences never leave your device.
Accuracy & Quality Commitment
Every formula used across our tools is verified against standard ceramic engineering principles and pottery studio best practices. We continuous update our toolset based on feedback from studio owners, pottery educators, and ceramic artists worldwide.
