Again, coat every delicate surface
with yellow ocher, including the thin
wires where they extend outward,
and apply heat from the torch, using
the #0 tip. Heat until the solder fi ller
burns off and the silver fl ows. Quench,
pickle, and rinse. The 20-gauge wires
also are extra long to dissipate heat
and protect them from melting.

Use fi ne, round-tipped pliers
and fi ne-tipped cutters to curl
and trim the 20-gauge wires into eye-
lets. Flux the piece all over again, and
coat at-risk details with yellow ocher.
Apply more extra easy paste solder
to close these eyelets, and focus a
low #01 tip fl ame on them until solder
fl ows. Quench, pickle, and rinse.

The last fabrication step is to
trim off the 20-gauge wires
between the twigs to open up the

Easier Ways



  • Do you belong to a rock club? Then
    you may know someone who’s into
    faceting. Create your design, and ask
    them if they would be willing to cut
    and polish stones for you.

  • Create a simple stone setting using
    sterling silver sheet and prongs
    embedded into your Solderite board.
    Solder a closed jump ring to the top,
    add a ready-made bail, and string from
    a chain.

  • I had a casting company make me
    a dozen sterling silver frogs, which
    are about ¾" in length. I’ve made
    frog pendants and clutch-back pins.
    You can solder them on to pieces of
    textured sheet, cut-out sterling silver
    washers, ring bands...

    • Turn your frogs into earrings. Add
      half-drilled pearls by soldering a
      closed jump ring onto the front toes.

    • Consider using a full-service casting
      company. They can scan, 3D print,
      and cast multiples of the rubber frog
      in Photo 12. Or any other small object
      you come across that you would like to
      have duplicated. I did that recently for
      a trout-inspired piece that appeared
      as “And Thereby Hangs a Tail” in the
      last issue.

    • Not into swamp things? Rio Grande
      and other catalog companies sell
      dozens of sterling silver charms and
      components, such as horses, panthers,
      dragonflies, wings, mermaids, initials,
      religious symbols, and scroll-work
      hearts, so there are lots of choices. Use
      these for your project.

      • If you’ve mastered making twig-like
        shapes out of sterling silver, consider
        fabricating twigs and turn them into
        rings, bangles, simple pendants, and
        brooches. Want to make multiples?
        Send your originals to your casting
        company. Have them make molds and
        reproduce your designs.

      • Do a riff on the half-drilled pearl I
        wire wrapped onto the bottom of the
        emerald pendant. It makes a great
        stand-alone piece if you epoxy it onto
        a larger wire wrapped eyelet, then
        string the pearl on a delicate chain.

view. Then sand away all rough edges
and polish the setting with Tripoli until
the silver shines.

FINAL POLISH AND
SET STONE
Although natural emeralds have a
hardness of 7½ to 8, they can chip
or break during setting because of
their inclusions. Same is true for the
RusGems emeralds I cut. Hardness is
the resistance to scratching; brittle-
ness is a diff erent matter.
Photos 16-18 feature a triangular
rose-cut emerald in a fl at back prong
setting. The gap was created when the
stone got hung up on some extra sol-
der on the prongs. (See this fi nished
project in Easier Ways below.)

16


The fi rst step is to make sure
the modifi ed rose cut fi ts
perfectly fl at in the setting.

17


Use a small bud bur and
sanding disks to cut away the
meniscus of solder between the
back plate and each prong.

18


Put the stone back in the
setting and mark where you
want to trim the prongs. Again, this
is an example of a triangular setting.
Each prong should be long enough
to bend over the second facet. At
the bench, trim the excess off with
a saw, then round each prong with
Moore’s sanding disks. Toss in a
shot-fi lled tumbler for an hour to
help harden surfaces.

19


The 12-gauge prongs are stiff
after tumbling. So, gently
anneal them with the small fl ame
of a #00 torch tip. Then thin them
some more with a sanding disk.
