Assertion (A): Kiln furniture is made as light as strength permits.
Reason (R): Every kilogram of furniture must be heated and cooled along with the ware.

  • A.A is false but R is true
  • B.Both A and R are true, and R is the correct explanation of A
  • C.Both A and R are true, but R is not the correct explanation of A
  • D.A is true but R is false

Answer: B

Correct answer: Both A and R are true, and R is the correct explanation of A

Both are true and the reason is the whole argument. Kiln furniture rides through the cycle with the ware and absorbs heat in proportion to its mass, so a heavy setting can consume more fuel than the ware itself. Lightweight cordierite and silicon carbide supports exist for that reason, and the ratio of ware to furniture is a standard measure of how well a kiln is being loaded.
