Assertion (A): Inspection is placed as early in a ceramic process as the defect can be detected.
Reason (R): A piece rejected later has consumed more energy and labour than one rejected early.

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

Answer: D

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

Both are true and the reason gives the economics. A defect present in the green body but not found until after firing has consumed the drying energy, the kiln time, the kiln furniture space and the handling in between. Detecting it at forming costs the material alone. The principle sets where inspection is placed: as early as the defect can be seen, not where it is most convenient to look.
