Practice question · True or false
Slip casting controls wall thickness by how long the slip is left standing in the mould.
Hints
- Ask what the porous plaster is doing while the slip sits there.
- It draws water out and a wall builds against the face.
Show the answer
True
Why
True, and it makes slip casting unusual: time directly sets the geometry. The porous plaster draws water from the slip against its face, a wall of clay builds up, and pouring off the excess sooner or later gives a thinner or thicker wall from the identical mould.
