Making a Basket
At
first our baskets were basic round reed replicas using sterling silver
wire. As we gained more knowledge of and with the metal, we began to
expand the range of styles we used for baskets.
Sterling silver is pure silver alloyed with copper, which gives it
strength and durability. We use a rolling mill, which is a pair of
adjustable steel rollers that flatten round wire uniformly.
Rolling the correct gauge wire to achieve the width or thickness of
strands needed for weaving a specific basket helps us to produce the
correct scale.
When metal is wrought with a hammer or rolled through a rolling mill,
it is work hardened, or more simply “tense”. To continue to work with
it could cause a fracture. It must be annealed, a process of heating and
slow cooling, to restore its original flexibility. Although, annealing can
be accomplished with either a kiln or a torch, we prefer to use a torch.
For silver the annealing temperature is about 1100*F. and when it cools it
is soft “relaxed” and ready to use.
We use
white pine wood to make most of our forms. Or, if a harder surface is
needed we use black walnut. Straight-sided forms are sawn with a small
band saw, while curved shapes are carved with a knife. Oval forms are the
most difficult to make. Sometimes a test basket has to be made on a new
form to check its trueness. Then, if necessary, further refinement can
achieve the desired shape.
Metal
basketry is like natural fiber basketry in that you must rely on instinct
and experience to help decide on the size of material for the rim, ribs,
and so on. We put our metal baskets together just like natural fiber
baskets, with the exception of soldering in certain spots on occasion.
Metal strands slip against themselves, unlike natural fibers that cling to
each other. Other than this, there are no real restrictions to weaving
baskets with metal.
There are several options for finishing a basket: 0000 steel wool
produces a soft, brushed look. A buffing machine provides a high polish
with a muslin wheel or a bristle brush. We often oxidize the baskets using
a liver of sulfur painted on the surface that turns the metal black. When
buffed with steel wool or a brush wheel on a buffing machine, only the
high spots get polished, leaving darkened areas that help create an
antique look
