A worked example
200 × 150 × 6 mm is 180 cm³; at 1.8 g/cm³ it is 324 g before extra material.
Slab material
Estimate a rectangular slab’s volume and mass from dimensions and your clay density.

THE METHOD / 01
A clear wayfrom start to finish.
Volume in cm³ = length × width × thickness in mm / 1,000. Mass = volume × density × (1 + extra / 100).
Keep the assumptions clear
Density is an entered estimate, not a universal clay constant. This does not estimate kiln energy or firing safety.
