Panels Re-Do

*le sigh*

I started working on a couple of lamp panels several years ago (I think it is three years ago, although I am ashamed to admit that was the last time I had studio space set up…) and I recently pulled them out again to finish them as part of my goal to complete old projects before working on new ones…  Sadly, the copper foil oxidized and soldering the pieces together (over the old solder and bad copper foil) was just not going very well.

Oxidized copper foil

I decided I would pull all the old copper foil off, replace it with new foil and just start over.  {You can see the process for how I did this in my post on fixing up the hummingbird sun-catcher.}  Removing the copper foil was time consuming and annoying, especially so with several components of textured glass, but in the end it made soldering everything much easier, cleaner and produced better results.

This is the solder result from the panel that I just worked on soldering over as-is.  There was not as much oxidization on the copper foil as on the panel in the picture above, and I figured I could probably make it work:

Bad solder...

These solder lines didn’t melt as smoothly on the fixed-up panels – and the finish on it is kind of grainy and dull, like it tarnished faster than the solder on the panels where I replaced the foil.  Here’s what those solder lines look like:

Ok, so maybe my photos aren’t quite the best…  But you can kind of get the idea that this solder line is smoother, plumper and shinier.  The soldering process went much faster as well because the copper foil was new, and everything was just happy to stick together.  After my first attempt to solder the original copper foil panels, I figured something a bit more intensive would be required to get the solder to bond to the copper without totally starting over — so I scrubbed everything down (old solder, recent solder, copper foil, glass) with a bit of soap and steel wool to clean the existing materials and rough-up the copper for a better bond.  It works – I got the rest of the solder lines onto the panels without too much trouble.

Up next?  Finishing the top piece of this lamp box and connecting all the pieces together!
