ceramic molds

Post by BobbieMatus »

Is there a way to clean off the accumulated kiln wash on ceramic molds. Every time I slump pieces of kiln wash get embedded on my piece.

User wet/dry sandpaper, fine.

When you reapply, you don't need that many coats. Two or three will work fine.

Yes, drywall sanding mesh works best. It's also what I use to clean my shelves. Works great. Wear gloves though. It's rough on your hands.

Hi

To clean shelves: I place them on a couple of pages of newspaper. Spray the surface with water to keep the dust down, scrape with a paint scraper. It forms small flakes that are collected into the newspaper. If needed I wash any left over rests under a tap (outside).

To clean molds: I wash them with a plastic scrubby in a bucket of water. Rinse and leave to dry, then reapply separator.

Please consider I am doing this outside. Wouldn't be good for the plumbing.

Best regards, seachange

If kiln wash gets embedded in your glass during a slump, then I think you are slumping at too high of a temperature.

2 cents,

I coated my moulds once when they were new and never again!... some I've been using 20yrs. never had to recoat. I agree with the last post your top slumping temp should be low enough that melting against mold should not be happening!!
