The transition from the constant rate to the falling rate period occurs at

  • A.the plastic limit of the clay
  • B.the liquid limit of the clay
  • C.the point at which firing begins
  • D.the critical moisture content

Answer: D

Correct answer: the critical moisture content

The critical moisture content is the point at which the surface can no longer be kept saturated by migration from within, so the evaporation front retreats into the body and the rate begins to fall. Practically it is the point at which shrinkage ends, and it is why a drying schedule is cautious up to it and can be aggressive after.
