State whether the following is true or false.
Recipe arithmetic errors usually show up as a change in fired properties rather than as an obvious mistake.

  • A.True
  • B.False
  • C.True only at large scales
  • D.False only at small scales

Answer: A

Correct answer: True

A batch error rarely announces itself: the materials look right, the slip pours, the piece forms and dries. The consequence appears at the kiln as a shift in shrinkage, colour, porosity or fired strength - days later, on a whole batch, with the cause several steps upstream. That is why weighings are checked at the time and recorded, rather than being reconstructed afterwards.
