5 Reasons Why Clay Becomes Bone Dry at Different
Rates

• 1. Humidity clay dries faster in drier locations
  like Arizona than in Wisconsin

4
2.    Thickness

• Thin walls dry faster than thick walls

5
3. Surface Area

• The more exposed surface area the faster the
  surface will dry
• Projections and appendages dry faster than the
  main pot

6
4. Air Movement

• The side of the project that faces a breeze will
  dry first

7
5. Overall Size of the Form

• Large pots dry slower than small ones

8
Force Drying

• Placing a wet piece in the sun, under heat lamps,
  using a hairdryer, or heating vent to dry the
  piece quickly.

9
1st Reason to Avoid Force Drying

• 1.  Pieces drying unevenly will appear dry but
  firing the piece will cause it to explode.

10
2nd Reason to Avoid Force Drying

• When clay dries quickly it causes stress cracks
  and pieces can fall apart

11
3rd Reason to Avoid Force Drying

• When surface area dries too quickly it shrinks
  more quickly than the clay beneath causing the
  piece to warp.

12
Air Dry Rack

• Drying rack that has shelves made so that air can
  reach all surfaces of the clay as it dries. Pots
  dry from the top down so turn pots upside-down on
  rack

• For clay that is slightly too hard but can be
  dented with gentle fingernail pressure
