first attempt - cooked to 1500F. Too hot!
2nd attempt. Glued red stringers based on graph paper under the glass
post fuse - 1400F with 20 min soak. Then saw it round.

12" The bubbles all collapsed. My theory is that the 2 cases I've done this in did not extend the stringers to the edge of the piece. I suspect the center lifts up and lets the air out as the edges droop. The next thing to try is to put clear spacers to prop up the edges. |
9" round; pale blue on clear. Dark blue stringers. Used ~1/2"x1/4" clear spacers around the rim. The bubbles survived, so the sagging theory seems to be correct. Now to figure how to make the spacers more innocuous in the final product!
