I remember I saw a post about wrapping brass up in metal “clothe” prior to annealing and adding charcoal to it so that it doesn’t “scale” the brass. I used aluminum foil to wrap up the brass but turns out the aluminum foil became extremely brittle and just flake off after attempting to remove from the kiln, leaving a mess in the kiln while hot. The brass came with no scales at all. All I need is the metal clothe that was talked about in a post. Not sure what’s it call?
