Discussion
Consider the following statements about drying faults.
1. Cracks arise from differential shrinkage between surface and interior.
2. Uniform section thickness reduces the risk.
3. Warping is always caused by faults in the kiln.
Answer: C
The first two are correct. The third ignores drying entirely, and a great deal of warping originates in uneven drying long before the piece reaches the kiln. Tracing a warp to its true origin usually means looking at the dryer.
