Solutions For Flaky Kiln Wash

Recommended Posts

Keep these shelves away from your salt kiln as Flint/silica is a glass former.



Yes, silica is a glass former. But in a salt kiln, silica by itself will not flux out. It requires the presence of alumina and the resulting eutectic of silica/alumina/soda in order for any glass to form. So yes, you are correct that your kiln wash formula won't work in a salt kiln, but not because of the silica alone.
