Glaze Calculator Notes:

  • Raw Material List that comprise the base glaze must add up to 100%.

  • List any additives, such as oxides, in the Colorants section. The sum of Addons is in addition to the formula's 100%. For this reason, batch size is increased by the calculated amount of Colorants. For example, if making a 1000 gram batch size of a glaze with 1.5% additives, the final weight will be 1015 grams.

  • Raw material must have unique names; Likewise for additives.
