I just finished fusing a Spectrum 96 compatible glass 12″x12″ 1.5″ thick piece and want to tack fuse an accent piece on the top. The top piece will be a 9″x5″ oval made of 2 fused pieces. I’m struggling to calculate the proper segment lengths. The original fusing took almost 2 days. Any insight would be welcomed.June 5, 2012 at 7:27 am #12545Stephen RichardParticipant
You are trying something difficut.
I suggest (in degrees F)
11/hr to 510 no soak, 17/hr to 1000. Start checking from about 600, as there will be a lot of heat work put into the piece by this time. It might even be tack fused at a lower temperature.
Anneal cool should be on a slower schedule than previously, as the tacked parts will try to pull away from the big block.
So I suggest 3.5 days for heat up and 2 days for cool down to be sure everything is secure.
Is there another way you can do this?

Thanks for the response. Your calculations are similiar to what I was coming up with so I guess I’m on the right track. I was seriously considering just creating the separate piece to a ‘finish’ and then attaching it with glue instead of going through this process which could end of in catastrophe. Giving it some thought…
