STERLING SILVER is a binary Silver alloy consisting of:
925 parts/1000 Pure Silver and
75 parts/1000 Pure Copper.
Annealing temperature: 750 degrees Celsius.
Melting Temperature: 950 degrees Celsius.
Ebony is a tropical hardwood. There are two types,
the African, which is very black, and the Ceylon or
Macassar, which is a dark brown with black grain.
The one I use is macassar, because the trees grow
to a larger diameter, and therefore allow larger
single pieces of work to be made.
CONING AND RAISING.
Coning and Raising is where you make a cone out of
sheet metal with a special overlap seam, which can
withstand the rigours of raising. The Item may then be
raised over a conical stake, or on pitch, if it is too
narrow for a stake to fit in.
Raising is a method of shrinking sheet metal in order to
form hollow shapes. For instance: a bowl, or a
jug may be raised from flat sheet metal in one
single piece. During the process the metal
Répoussé is a method of sheet metal forming
where the metal is placed on a bowl of softish
pitch. The metal is then hit down into the pitch
with smooth punches. If the desired result needs
greater depth or more refining, the work may be
turned over and worked from the other side. The
pitch supports the metal where it is not being hit,
and in this way three dimensional shapes of great
depth can be achieved.
Some confusion exists in the English speaking
world, because the word "CHASING" is used for two
different techniques. In German the word for
chasing, is zisellieren, or chiselling. The object
to be decorated is placed on a quite hard "chasers
pitch", and is then worked with small cutting
punches. the look is somewhat like engraving.
CARVING may be done by various methods, such as:
Chiselling, engraving, or with a rotary burr in a
flexible shaft machine.
Engraving is surface decoration, usually used to inscribe
lettering, but it may be used to put any design on
the surface. In engraving a small cutting chisel,
called a graver or scorper, is used to cut small
channels into the surface of the metal. If the
graver is well polished, it leaves a very polished
cut. This is sometimes called bright cutting.
