Electric kilns are preferred to gas kilns where

  • A.the largest possible kiln volume is what is needed
  • B.fuel cost is the only consideration that matters
  • C.precise temperature control matters more than atmosphere
  • D.a strongly reducing kiln atmosphere is required throughout

Answer: C

Resistance heating gives close control and a clean oxidising atmosphere, which suits technical ceramics and many glazes. Producing a genuine reducing atmosphere in an electric kiln is awkward and shortens the element life.
