The production of the "Modern Vienna Bronzes" is still following the same
procedure as in the past. Initially, around the middle of the last
century, sand casting was used, an extremely difficult method, but still
employed today e.g. in bell-founding.
In the Sixties, this procedure was replaced by centrifugal casting,
which was more efficient
and also provided better quality castings. Nowadays
BOSSE replicas are cast in vacuum. The same pinciple is applied by the
goldsmith in the manufacture of jewelry made of precious metals.
In the following we shall depict and illustrate the main steps of brass
casting.
