The function of the wax resist is to keep liquids, such as raw liquid glazes, from adhering to the clay body of a pot. The most common use for wax resists is also the most practical. Any speck of glaze material on the bottom of a pot can cause it to weld to the kiln shelf during firing.
What happens if you over glaze?
Applying glaze too thinly can result in rough glazes and can affect the glaze’s color. Applying glaze too thickly can cause the glaze to run off the pot, weld lids to pots and pots to kiln shelves, and can result in blistering.
