I make a number of jewelry pieces that consist of a pierced layer of
metal soldered to a backing layer, often quite detailed with lots of
narrow strips of metal. I’ve been sweat-soldering these to their
backing, but the process of placing teeny bits of solder all over
the back of the pierced layer is very time-consuming. I’ve tried pre-
sweating evenly placed pallions across the back before piercing, but
this creates bumps that interrupt sawing and often leaves areas that
must still have solder added.
I’d like to cover the back of the metal I’m piercing with a
perfectly even, gapless layer of solder before piercing - almost like
a bimetal. I was thinking I might roll some solder down super-thin
and then apply it - anybody done this? Will it just puddle?
I was also wondering if I could use a similar process to apply a
thin coating of silver-rich solder to the back of copper pieces, to
keep from turning the wearer’s skin green.
Many thanks for all your help,
