@livinit04 cement and whiting powder should always be used in lead applications for strenth and stability.

@ladylinda321 You are very welcome! You don't necessarily need a solder line for the rebar to work but it can help to mask it. Generally, however, it's not as noticable as you might think.

Thank at has been very helpful.. What Im hearing is I need a solder line that goes from one side to the other with a rebar inserted

I'm using 1/4" round U-shaped lead came to frame a panel that is 20"x12" with the top arched. Do I need to cement/whiting?

@ladylinda321 if it's an interior window either method is acceptable. A panel that large will require reinforcement or it can buckle or warp over time. I spoke with my resident expert in stained glass and she said one piece of rebar running across the panel in the center (18") would suffice. The rebar would need to run from the outside edge of the frame on one side to the outside edge of the frame on the other.

it will be an interior window with a 44x44 as the exterior I didn't understand the rebar caoomnt

@ladylinda321 if your window is an exterior window it should be done in lead. Lead flexes where soldered copper foil is rigid - any change in temperature could cause your glass to crack. It should be framed with zinc came - at least 3/8" or 1/2" for strength unless you're putting it into a wood frame - then you could go smaller. At 36" you will need to reinforce your window with zinc rebar - probably three strips running side to side in a vertical window or up and down in a transom.

I am working on an octagon 36" window and am wondering if I can do it in the tiffany style or do I have to lead it? If Tiffany is ok is there anything I should know about framing it?

@roxe If you look at the images of the adjustable zinc came on the web page you will notice there is a small split at the bottom of the channel. This allows it to be adjusted slightly to accommodate textured glass or a foiled edge. Rigid came is typically used to strengthen the panel for hanging.

I don't understand "adjustable zinc came" it there a video tutorial or picture anywhere? How is it adjusted? Been searching the web. I've always used simple U shape came on the edges. thanks
