Covering for kiln wash
by June Askew
(Maleny, Queensland, Australia.)
My instructor told me to use Aluminum Hydrate powder after the kiln wash has dried thoroughly.
You wear a mask as it is not healthy to breath in, I have a plastic tea strainer which is small.
I put a small amount into that & tap on it lightly spreading over the kiln wash where you are placing your glass.
Then take it to the laundry or a wash basin & brush it gently off with a cheap paint brush & flush down the sink.
This is because if you leave it in tiny lumps they will imprint into the glass.
I find it much better than the kiln shelf paper, that used to make pit marks on the back of my pendants but no more since then.
Good Luck & don't forget to brush off the surplus powder.
