Gold Cast Demonstration
This is the standard flow of a casting. I could be gold or silver. This demo is shown
using our smaller Naycraft centrifical caster. We use this often for small casts.
|
|
|
|
 |
|
|
|
This casting starts with
a carefully measured
amount of 14k yellow
gold casting grains.
They sit ready for
some heat in the
Naycraft's ceramic
crucible.
|
|
|
|
|
|
 |
|
|
|
The casting grains
are heated with a
blowtorch. While
somewhat crude, it's
simple and allows our
goldsmith a lot of
flexibility.
|
|
|
|
|
|
 |
|
|
|
As the heat rises,
the entire crucible
glows and the grains
begin the melt.
|
|
|
|
|
|
 |
|
|
|
In just a few minutes
the grains have
completely melted
into a glowing
bubble of liquid gold.
|
|
|
|
|
|
 |
|
|
|
With one flick of
the wrist, the
casting unit spins.
The centripital
acceleration forces
the gold into the
mold.
|
|
|
|
|
|
 |
|
|
|
Only the "button" is
visible in the bottom of
the flask. This is the
entry point for the
molten gold which then
spreads out into the
cavities of the mold
creating each piece.
|
|
|
|
|
|
 |
|
|
|
A quick douse in
cool water causes
the hot mold (a
type of plaster) to
bubble and melt
away.
|
|
|
|
|
|
 |
|
|
|
Out of the water comes a
finished "tree" of cast
gold pieces. Our
multi-piece jewelry is
cast as idividual parts
which are later laser
welded or soldered
together.
|
|
|
|
|
|
 |
|
|
|
Freshly cut away from
the tree, this ring was
set with diamonds and
a gorgeous Red
Sunstones. Baskets
were welded into
place in the center
and stones set.
