Fired clay size from wet dimensions

Set these parameters: “Linear shrinkage”. In Numloom, enter “Wet clay dimension” (mm) to obtain “Fired clay dimension” (mm).

Calculations currently require access to Numloom on Google Play Internal Testing. iPhone and iPad support is planned.

How it works

Fired clay dimension = Wet clay dimension × (1 − Linear shrinkage ÷ 100)

In Numloom: “Wet clay dimension” → “Fired clay dimension”.

Linear shrinkage · %

This page shows the formula and parameters. The calculation runs in Numloom.

Assumptions and limits

Calculation basis: “Wet clay dimension” (mm) → “Fired clay dimension” (mm). Use the parameters shown for this particular operation.

Use shrinkage measured between the two stated stages for this clay. Dimensional shrinkage is not loss of mass.

Enter a non-negative value in the app.

Coefficient sources

Initial settings: Linear shrinkage = 10 % (example in the original task description).

These starting values are not a standard, calibration certificate or manufacturer recommendation. Replace them with values measured for your process or specified for your product.
