Removing Oxidation
by Charlene
(Newport News, VA, USA)
I started to make a lamp about 4 years ago and only got as far as the flat soldering on the outside of the lamp and tacking the inside of the lamp. Unfortunately, I wasn't able to get back to the lamp and now that I have the time, the solder won't stay because of the oxidation. What would be the best way to remove the oxidation. Thanks.
AnswerHi Charlene,
I'm assuming the lamp is constructed with copper foil. The best way to clean it up is to go over the foil (and any existing solder) with very fine steel wool, or better yet bronze wool. Bronze wool can be obtained through some stained glass retail shops or
Glass Crafters Wipe the panels down with a damp cloth, after you remove the oxidation, to get rid of any residue from cleaning off the oxidation. Then you just solder as usual. You shouldn't have any more trouble with the solder not sticking.
If the panels are sticky from flux setting on them for four years, wipe them with alcohol before you start cleaning them with the steel or bronze wool.
