hi everyone, I hope somebody can answer me… I am trying to fuse resycle bottle glass at the bottom of trays made out of clay…my kiln only reachs 1800F, but istead of have a smooth glass surface i end up with a bunch of holes ,and in some areas no cover with glass even when I put plenty of it…( seem like the glass is not getting as liquid as I thought even when i fuse it at 1800 for 2 hours) how can i get rid of these holes? you think if I add fist a coat of clear glaze the glass will spread better on the entire bottom suface.
thanks
