​How to Repair a Broken Copper Foil Panel

​It's truly unfortunate ​that ​accidents happen and beautiful​ copper foil window panels get damaged. But it's a reality when dealing with glass that sometimes​ they do get broken.

​Repairing broken pieces takes time and patience, but even if you're still fairly new to making stained glass, you can still benefit from learning how it's done. Sooner or later you'll have a piece that needs repairing.

Over the years, I've had a few projects that needed repairing before they were even completed! It was usually due to a heat crack that turned up during soldering.​ Maybe you've ​had pieces in need of repair from accidental breakage too?

Well, if you do have some, ​​now you can see the process to repair them.

​I've created a video that walks you through how a repair is done, complete from removing the broken piece of glass all the way through soldering the new one in place. ​This ​video shows a broken piece of glass in the middle of a copper foil stained glass panel and all of the steps needed to repair it.​

​Want to know what tools and supplies I used in the video? ​Here's a h​andy list.

​Give ​it a try!

​Every repair brings​ unique challenge​s and you'll learn a lot from doing them.

I suggest starting with a simpler repair like the one shown in the video. The panel didn't bend or break in multiple spots which means that the integrity of the structure was still intact.  This means that you can focus completely on the one piece without fear of the panel being unstable or easily fractured elsewhere simply by turning the piece about or tapping on the broken section.

Thanks for this great video. Making a foil repair now seems more achievable. However, I do have one question. When you heated the solder and removed the foil from the opening, did it leave the foil intact on the surrounding edges? You didn’t mention having to refoil the surrounding glass pieces before you put in the newly cut replacement piece.

    I”m glad you found it helpful BJ. When I was melting the solder and carefully pulling the foil away using the pliers, that was the foil from the broken piece of glass. All of the foil on the neighboring pieces was left completely intact. It’s important to work slowly and make sure the solder is molten before pulling the foil so as not to damage the copper foil on the surrounding pieces. If you do damage the foil on the surrounding pieces, you’ll need to remove them and re-foil them before assembling the window again.

I have a problem. Copper patina on eagle just finished has spots that look tarnished. Have added more patina, cleaned and polished and still it is there!!!

    Hello Judie, I don’t know what would cause the spots like you mention, I’ve never seen that before. Perhaps something dripped on your project before you added the patins? You might try scrubbing the solder with steel wool, cleaning it and applying the patina again. If that doesn’t work, applying flux and re-soldering the areas with the spots should get rid of whatever the contamination was that caused the spots. Then you could clean it and apply patina as you normally would on a clean slate.
