High humidity in the early stages of drying is used to

  • A.prevent the body from shrinking at all
  • B.raise the temperature of the piece
  • C.slow the surface drying and reduce the gradient
  • D.speed the removal of water as much as possible

Answer: C

Wet air near the surface reduces the evaporation rate, so the interior has time to keep up. It is the standard remedy where a shape is prone to cracking and cannot be redesigned. Humidity is reduced progressively as the piece becomes safer.
