Onglaze or enamel decoration differs from underglaze in that it is

  • A.fired on afterwards at a lower temperature
  • B.applied before the ware has been biscuit fired
  • C.mixed into the clay body before it is formed
  • D.never fired at any point in the process at all

Answer: A

Correct answer: fired on afterwards at a lower temperature

Onglaze or enamel decoration is applied to the already fired glaze surface and fixed in a third firing at 700 to 900 degrees. Underglaze is applied to the biscuit before glazing and is then covered and fired with the glaze at full temperature. The difference in firing temperature is what accounts for everything else about the two - as the next item sets out.
