CASTING is a method by which moulten metal is poured into a mold
in order to achieve the desired shape. In the "Lost
Wax" method, an accurate wax model is made. The wax
model is invested (put in a chrystobalite plaster),
after the investment has set, the wax is burned out in
a Kiln. This leaves a negative cavity into which the
moulten metal may be poured.
Wal.
FORGING is a method of deforming metal with a hammer on an anvil.
In the case of Sterling Silver and the Karat Golds, this
must be done COLD! If a hot forging is attempted the
precious metals will just crumble. In their PURE form
Silver and Gold will allow HOT forging, but there is no
benefit to be gained.

Burnishing is an old method of polishing metal. By rubbing
the surface of the metal to be polished with a
highly polished piece of steel called a burnisher,
the surface itself becomes polished.
Wal.
Scratch brushing is a way of finishing Silver by brushing
with a very fine brass brush, lubricated with
detergent, in order to create a bright but soft
look. First the item to be scratch brushed, is
finely polished. The item is then annealed and
pickled, and then scratch brushed. The entire
process is repeated 3 times.

Fire gilding is a method of applying Gold to the
surface of an object. 24K Gold is dissolved in
mercury, and the resulting amalgam is rubbed onto
the surface where the Gold is to be applied. The
mercury takes the gold into the surface of the
silver and the mercury is then driven off with
heat. This creates a permanent bond between the
Gold and the Silver. The gold is then polished with
a burnisher.
Mercury vapour is poisonous, and should be handled
in a fume cupboard. The fumes must not be inhaled.
