The challenging complexity involved in the creation of
take-away sculptures - and because there can be only one
- make these pieces among the most prized in the art world.
There is simply no way to reproduce a stone or marble
sculpture.
The second method of sculpting is called Adding On.
All other forms of sculptures fall under this category. This
includes bronze, Lucite, plaster, and pretty much anything
else the artist's eye can come up with.
With the adding on method the artist begins with a
vision; then they take clay and "add it on" to a metal
framework, creating a clay or wax model of their vision.
Once the artist has decided the model is `just right'' they will
begin the process of creating reproductions of this model.
Bronze sculptures are the most popular of media
among "addition" sculptures. With most bronze sculptures
once the working model is perfected a clay model of actual
size is made using a larger metal frame and more clay.
After the actual size model is detailed and ready "the lost
wax process" begins.
In the first stage of the lost wax process the detailed
model is used to create a cast image of the sculpture. Wax
is then hand poured into this casting; the hand pouring
is what determines the final thickness and weight of the
bronze sculpture.
When the wax cools the image is dipped into a liquid
ceramic. This ceramic when hardened can withstand the
extreme heat of molten bronze. But before the bronze is
poured into the ceramic, the wax must either be
melted or evaporated away. Thus the term "lost wax"
process. Once the wax is "lost" molten bronze is poured into
the ceramic cast and presto! You have a bronze sculpture.
