I'm confused with the anneal 9999. I've read many posts, but don't understand the 9999.

@justinew18 If you frame your project with 1/4" U Zinc it will be strong enough to stop folding. 3/8" Zinc will also work.

@We recommend 3/8" for most projects 8" x 11" to 2' x 3'. Larger projects we recommend 1/2" came.

Hi, I am making 2 small copper foil panels for an internal door. They measure 13" by 6" and the pattern is oblong strips placed in a brickwork pattern that runs vertically. Do you think these should be reinforced due to the hinge joints and if so where would you recommend placing the reinforcement. Many thanks.

@skincaid2 We recommend Handy Hangers item

@jamesandpatricia3103181120 Since you would prefer not to use rebar we would recommend 3 separate panels.

I am making a 13x26 panel to hang in a window. What size rings should I use to attach at the caming?

Making 11" x 69" stained glass on top of existing transom. will divide into 3 pieces because of length. would it be better to use one long piece of u zinc came on top & bottom & just put 2 ea.11" pieces vertically soldered in to separate for strength or should I just make 3 separate panels? I don't like the reinforcing bars or rods for my design. Or, would reinforcing steel strips be better. Concerned about buckling & installation. thanks

@Yes, you can fuse glass to itself. As long as you are fusing the same sheet together. If you are wanting to fuse 2 separate pieces we don't recommend that. Here is a link to our fusing tip sheet. https://www.delphiglass.com/page/knowledgeBaseView?KBItemID=90

@Lynn.mueller You can use your current fusing schedule and add in a segment that will hold once you reach 1225* F. For small pieces such as your 4" square we suggest holding at a minimum of 30 minutes. For larger pieces (12" or up) we recommend holding for 60 minutes. For your 10" piece you could meet in the middle at 45 minutes. You can't over hold a piece so you could always holder longer if you prefer.
