Thanks for your reply. The Maryland Institute, College of Art
Jewelry Center is a great place to learn and work. They were
written up in the August issue (I think it was August-definitely
this summer) of Lapidary Journal. The instructors and
atmosphere is incredible.
For the granulation, you heat the piece, with the granules glued
on, with a medium torch head (we were using #1 or #2 torch heads
with acetyline gas) and a low-pressure, very, very bushy soft
flame. You don’t want to force a lot of heat on the piece, but
really just pass the torch back and forth over the piece with
the furthest end of the flame just “kissing” the piece. You
need to watch closely and you will see a small flash at the base
of the granules, indicating that they have fused. If you
practice a few times, the flash gets easier to see. The split
second you see the flash, remove the flame. Especially with
fine silver, if you don’t get the flame out of there you will
slump the granules and even melt the piece.
I hope this helps. Sorry about the small novel, part II.
