Enamel Question


#1

Orchid Enamelers. I would like to attempt a project where I am
enameling into a etched copper piece [14g] that is soldered onto
another 14g copper piece. I will be making enameled grips for a very
small hand gun. The smaller backing piece will fit into the hollows
of the handle and the larger top piece will carry the enamel.

I would use IT solder but my concern is the silver solder between
the two copper blanks. I know that fine silver wire sitting on bare
copper will alloy itself into sterling and pool or “melt” right
through the copper in the temperatures of the kiln. I suspect this
same thing will happen with the solder, alloying itself into the 2
surfaces of the blanks. Is this a problem? I intend to create some
stabalizer pegs so the two pieces do not slide in relation to each
other.

I could make the whole grip using fine silver and forgo the hassle
but of course there would be a price difference. The price might be
worth it to avoid hassles. The grips are only about 2" x 1-1/4". I
know that fine silver is soft but the grip is supported by the
framework of the steel gun plus this gun will never be used [is
non-working and will only be on display]

Do you have any suggestions?

Use the 72/28 eutectic alloy sold by Thompson Enamel Co as IT solder

  • use just enough to do the job - it’ll be fine !

Why not have them cast in Sterling silver - I mean "Sterling"
Sterling silver here - 92.5% pure silver with 7.5% pure copper and
nothing else. The material cost is trivial c.f. your labour costs.
