Kennedi, Glad you liked the DVDs on Granulation.
Using the ultra-light kiln and torch method, how much is it
acceptable to increase the gauge of background sheet? I would like
to get a bit more "heft" out of the pieces I make. What gauge of
fine silver sheet would you not recommend going above?
The thickness of the base really depends on how heavily decorated
the surface is. The thicker base is difficult to get to the proper
temperature without overheating the granules or wires on the
surface. the granules want to fuse together and not to the base. If
you see the granules flash on top before the background flashes, then
the granules are too hot.
Assuming that it is OK to work with something like a 20 gauge
background sheet, should I use slightly larger granules and
background wire to get a proportionally larger fillet on firing?
Exactly. The background sheet should be in proportion to the
granules and wires.
Conversly, is it OK to vary the gauge of the wire used for
background detail regardless of the gauge of the background sheet?
Again, it depends on how much mass is on the surface. More mass
(wires or granules) thinner base. Heavier wires will need more heat
than fine ones. You might have to do the various wires in individual
firings from heaviest to thinest.
Does anyone have any books / resources that anyone would recommend
where I could learn more about the history of granulation?
"Greek Gold" is one of my favorites. I had wanted to put more about
the history in the DVDs, but didn't want them to be too long and
there is SOOOO much to cover.
FWIW, I used honey as my "glue" because I couldn't get my hands on
any hide glue. Haven't had a problem yet! Thanks again to
Orchidians who posted the honey tip! Suggestions are always welcome
off line as well as on.
Any organic glue will work. It leaves a carbon that aids in the
