Having reiterated that there is no solder that will yield a
copper-colored seam, I may have found one.
I bought some “Copper Wire Solder #801” from Caldron Crafts
(www.caldroncrafts.com) a couple of years ago. I must have tried it
because I wrote “leaves grey seam” on the plastic bag. This summer I
was talking to the owner of Caldron Crafts who said she had talked
to the manufacturer of the solder who said that one should not use
any flux with this solder.
I finally tried it out on a copper jump ring (16-gauge wire). It was
not a great seam nor did I use a tiny amount of solder. So far, no
grey. I filed the seam a little, hammered the jump ring flat,
tumble-polished it in my ceramic media for a few hours, rubbed it
gently with 4/0 steel wool – still no grey.
The copper wire was from one of those little wooden spools from
years ago. I tried a second jump ring made of Rio’s copper wire –
I’m not sure the effect is so good. I need to try it again, but I’ve
run out of time for experimenting on this. Try it yourself – no
flux. Let Orchid know your results.
