If glaze is cracking on application or it too thick to brush, it may need an addition of Gum Solution.


Adding Gum Solution

Gum solution can be used to thin overly thick glazes, and bring them back to a brushable consistency, and to prevent glazes from cracking as they dry, which can lead to crawling on firing. AMACO Lab recommends using no more than 1/4 cup of distilled water to each Tablespoon of gum solution. Using distilled water instead of tap water will lengthen the effective time of the gum solution. Add the gum solution in small amounts, along with water, to thin glazes which are too thick. Add gum solution alone to glazes which are old, smell bad, or are cracking as they dry.
