Limit formulae list the oxides which should be used in a glaze for each firing temperature.

If you select the correct answer you will proceed to the next question.

Limit formulae give strict parameters for oxide levels in glazes at various specific temperatures.
Limit formulae suggest minimum and maximum levels for the molecular parts of glaze oxides in unity formulae at each firing temperature.
Limit formula are values for oxides which will reduce crazing if they are adhered to at each temperature.
