This is becoming big business in the jewellery trade. Reports are being =
posted
about workshops and training sessions for instructors. Looks like becoming a
fashion like hobby ceramics. The margin for success and disaster in the =
kiln, or
should it be a furnace is rather narrow. Claims are that it can be thrown on=
the
wheel. Would love to try the 18K gold=21 See recent issues of Lapidary =
Journal.

My experience with this stuff is very limited..but i do know that there is a
great deal of shrinkage when it is fired..I think it would not survive
being a chain dangling on the side of a pot. and i wonder about using it as
a "fill in" for carvings and lines.

There was a potter I knew who had an exhibition trick where he would use a
blow torch on a pre-fired and reheated pot to apply low-fired lustres.
the room would fill with fumes, I think he did it to discomfit the society
lady hangers on). I was wondering whether this could be done with silver
solder, using the appropriate flux, perhaps to run it into a groove on the
pot?

Jim,
I did some research with PMC back in 95 and 96, and can corroborate your
theses. Depending on firing temperature, shrinkage can be in the range of
20-30%. I used PMC as a crack filler as well. The trick seems to be to first
line the crack with a low melting frit or GB, then work in the PMC. Fire
quickly to cone 018.

At $26 for 20 grams of the clay, it would be unrealistic to consider throwing
on the wheel. The 22k gold is $265 for 10 grams!!!!!! Just thought you'd
like to know.....
