Practice question · Multiple choice
An armature prevents soft clay from slumping during modelling, but clay shrinks as it dries. What follows from this tension when choosing an internal support for ceramic sculpture?
Hints
- What happens mechanically when drying clay contracts against an unyielding internal core?
- How do ceramic armatures differ in handling from those used in non-fired sculpture?
Show the answer
C. Rigid supports demand a strategy for removal or burnout
Why
Rigid frames crack shrinking clay if retained, so ceramicists must hollow, withdraw, or burn out supports. Shrinkage cannot be resisted by force, nor does it preclude armatures altogether.
