Biscuit firing is carried out before glazing in order to

  • A.make the ware strong enough to handle and glaze
  • B.melt the glaze that has already been applied
  • C.remove the last of the shrinkage from the body
  • D.colour the body its final shade

Answer: A

A green piece is too fragile to dip in glaze and would soften in the slurry. The biscuit fire consolidates it while leaving it porous enough to absorb the glaze readily. Biscuit temperature is chosen for handling strength and porosity together.
