Batt WashBatt Wash
Batt Wash
This product will prevent drops of glaze from sticking to the bottom of the kiln or the kiln shelves. The wash binds with the glaze to make a brittle material that can easily be scraped off. It is recommended that the shelves be coated with a new coat of wash before each firing. Kiln shelves are quite expensive, so anything you can do to save them is well worth it! It is made by mixing with...
