Hello. On behalf of Expert Village, my name is Joe. I own "The Vug" local jewelry store
in Salt Lake City. Today, I'm going to talk about lost wax casting. I don't actually do
my own lost wax casting anymore in my store, because it takes an oven, which heats up my
store a little too much. I'll go over the basics of it though. Basically, you carve
a wax mold or you buy a pre-made wax mold and there's center fuse casting, which you
basically, you take this and you put in a, basically, a plaster mold, stick it in the
oven, and the wax burns away, leaving a Boyd in the mold. Basically, you take that hot
mold and you put it in a center fuse that spins, so you have a crucible full of gold
or silver, molten gold or silver, and you let the center fuse go and it spins the gold
or silver into the mold. Basically, cooling at the same time, so by the time it's cool,
you've got the metal piece instead of the wax. There's also vacuum casting, which is
the same concept, except it uses air to suck the gold, and gravity, to suck the gold down
into the plaster mold and after cooling, then basically you've got the harden metal in place
of the wax.
