Practice question · True or false
An armature must be removed before a model is moulded and cast, exactly as it must before firing.
Hints
- Ask what forced the removal in the ceramic case.
- Shrinkage around a rigid core, and the kiln, neither of which applies here.
Show the answer
False
Why
False. The armature comes out before firing because clay shrinks around a rigid core and because the core would not survive the kiln. A model destined for a mould does neither, so the armature stays in and can be as rigid as the job needs, pipe, batten and wire, with butterflies across a long span.
