Mica in Casting Mold

Post by Terry Gallentine »

Has anyone out there tried putting a thin coating of mica on the surfaces of a casting mold for a pot casting? Mainly I am curious as to whether the mica will move with the flowing glass or will it form a fairly uniform outer coating.

I found that with a mold containing mica in the mold matrix that the mica left marks in the glass.
Your experience may vary.
