Is Bat Wash The Same As Kiln Wash?
Is bat wash the same as kiln wash, which is used to keep drips of glaze from sticking to the kiln shelf? If not, what is bat wash, and what is in it?
Milly's reply:
Hi Stephanie, yes, exactly the same thing. If you want to make your own, mix equal parts of kaolin and alumina hydrate, storing in an airtight container. Find them in any ceramics supplier.
Mix 4/5 parts water to the powder when you're ready to use. Use exactly the same any kiln wash, to protect your kiln shelf, glass slumping molds or fused glass molds.
Don't forget to remove the kiln wash after each firing as it can discolour glass in subsequent firings.
