Help! Am trying to coat SS forms with kiln wash . . .

I'm a fair novice at slumping/draping glass and was trying to coat several stainless steel forms to use as draping molds. The Warm Glass book says to heat the molds to about 500F and then spray them with kiln wash - the water is supposed to evaporate on contact and the particulate to stay. However, when I try that, it looks like it's not covering enough. Anyone have any thoughts?

Be sure that you shake/stir often as you are spraying. Multiple layers.

Exactly. Multiple thin coats, preferably sprayed and you're good for years. Slumping molds don't require the kiln wash coating thickness that shelves rewuire because of the 300 - 400 degree difference in process
temperature.

Abrading the metal increases adhesion, sandblasting is best but anything helps, even steel wool. just try and get a "tooth" on the mold. Brock

Thanks so much!! I have a gray pad, but that's not giving enough of a tooth, so will go to something a little stronger.

If I'd been paying attention, I would have seen the post a couple of hours before mine on the same thing - sorry
