Practice question · Estimate
A form is modelled solid and must be fired. Roughly what maximum wall thickness, in centimetres, is the usual workshop guide after hollowing?
Estimate on a scale from 0 cm (0) to 8 cm (8).
Hints
- Thick walls trap steam.
- A couple of centimetres, as a guide rather than a constant.

Why
About two centimetres, as a guide. The safe thickness depends on the body, the form and the firing schedule, so the number is a rule of thumb rather than a constant, and the more important requirement is that the thickness be even, since a single thick section is what cracks.
