Bottle Book and ring issue

[DZap]

Sandie, don’t know if you have had a chance to check out Boyce’s bottle book, but I looked through my copy and didn’t see anything about getting the rings of the bottles rounded nicely.  Had a thought though (and bear with me as I am new to this)-In the tutorial on this site for “fused glass puddles”, there is a step where you shouldn’t fuse using paper but should instead fuse directly onto a kiln-washed shelf as the paper prevents the cabachons from “rounding”.  Do you think this might be a factor for what you are trying?
