This is my first post to this forum so I hope I'm doing this correctly. I have fired a tabletop, I'm away from the studio right now but I guess it's about 2 inches thick, 18 inches wide and 40 long. I scratched the surface while cold working (flipped it over on the table top side down and didn't realize some glass shards were on the surface) and would like to see if I could fire polish it back without losing the form of the piece, or the texture of the sides and shelf side. I know the goal is to create a firing schedule that does not thermal shock, and stays at a target temp of 1350 or 1375 just long enough to smooth the surface and not cause devit. I read that some say not to use fiber release papers between glass and forms but I feel that I'll lose texture if I don't, and I may lose the nice rectangular shape it I don't dam. Thoughts on a schedule and methodology appreciated. All except one 3mm layer is Tekta.
Thanks for the help! Bill
