The pins you see here have been made almost entirely by hand. Given the
increasing difficulty in finding people able to execute these exacting and
complex designs, we're certain they can only increase in value. This brief
description of the process can only give a hint of the substantial work
required to produce each pin.
The enamels themselves are glass, colored by metal oxides. They start out
as chunky material which is ground into a powder and screened to ensure
fineness. It's then mixed into a paste which is applied, one color at a
time, to its appointed place in the design. A small spoon, brush or even
syringe is used to place these colors; if a mistake is made the piece must
be repaired or discarded. Each color is fired separately so as not to bleed
into another. since each glaze has its own peculiarities and different
melting points, a firing order must be established. Some of the pins in
this catalog have as many as 13 separate glazes and require an astounding
amount of careful work for their completion.
The enamels are supported by copper, which is chosen for its ability to
take platings a well as its malleability, stability and non-corrosive
qualities. At Wm Spear Design, we use copper which has been recycled from
the ship breaking industry, insuring that 80% of the pin by weight is
recycled material. However, in order to give it shape it is first necessary
to create an engraved die in hardened tool steel. Although a rough shape
can be achieved with the careful use of a high speed drill, the spontaneous
feel, magnificent detail and relief engraving seen here can be achieved
only by a master engraver and by hand carving. Mistakes are of course
irretrievable. Unusual shapes and holes require supplemental dies.
The die is placed in a drop press in which pieces of copper are
individually loaded and shaped, one at a time, by bringing to bear
pressures of up to 300 tons which can crack or break a die. Dies can lose
their crispness with use a can pitting from disuse. Collectors are able to
easily detect enamels made from a counterfeit die since no two hand
fashioned items will ever look the same.
After completion of the enameling process the enamels are ground down to
the level of the underlying copper and carefully polished. The findings are
soldered on. Where the design allows, our U.S. made, two piece safety pins
are used and must be carefully measured and soldered into place. The pins
are then electroplated in gold. Wm Spear Design has pioneered a very labor
intensive dual plating technique which adds even more remarkable detail by
showing not one but two metal colors, say black and gold. All of these
processes will result in damage to a certain percentage of the pins which
must be discarded, thus making the acceptable ones that much more expensive
to produce.
