Hi, I am new to glass fusing & slumping & to this forum.I recently fused & slumped a tray, but during the slumping I think the pyrometer wire touched the edge of the glass & left a small indentation. I wish to smooth out this indentation, so is it possible to re-fuse the piece once it has been slumped, & is it possible to re-fuse it in the mold?. Thank you in advance for any advice you can give me.
It depends upon the mold as well as just how “indented” your mark is, but in most instances, your best bet is to refuse flat, and then reslump. If you have to fuse hotter than about 1250 deg F to get rid of the mark, you will most likely ruin the shape during the process even when placed in the mold.
