Sculpture I / Positives and the Multiple
Practice question · True or false

Slip casting controls wall thickness by how long the slip is left standing in the mould.

Hints
  1. Ask what the porous plaster is doing while the slip sits there.
  2. 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.
