If the overhang is only an inch or so, you can surround the mold with kiln furniture that is higher than the mold, top each post with fiber paper and lay the glass on the furniture instead of the mold. It will hold the glass up so it doesn't sag over the edge of the mold. The furniture spacing depends on the size, but the more glass you have outside the mold, the closer together you must put the posts, to prevent glass from sagging down between them and getting stuck.
