Potters who mass-produce Ceramics prefer this method because it only takes seconds to coat bisque ware.
What is the difference between dipping glaze and brushing glaze?
Dipping glazes are generally thinner than brush-on glazes. With Dipping, pottery needs to be easily sunken into the glaze to get a nice, even coat, hence why dipping glazes are thinner. Whereas brushing, you apply at least two, generally three coats of glaze.

What does bone ash do in a glaze?
When added to a clay body such as bone china, bone ash lowers the maturing temperature and adds translucency. Bone ash may also be used to give texture in low fire glazes. In low-fire glazes, bone ash acts as an opacifier, while in high-fire glazes it can create translucence.
Can you Refire crawled glaze?
