The "Zeus" of Athens, the Horses of Saint Mark's in Venice, the "Marco Aurelio" of the Campidoglio in Rome, the large sculptures of the Renaissance have been made with the same procedure that, through the time, has remained partially unchanged.
This technique consists in covering with wax, that will be later modelled a refractory clay support; then another clay layer is put on the wax so that is encased between two masses of clay.
By heating this clay container to a high heat, the wax melts and drips ut through some purposely made holes.
The liquid alloy is then poured into the thin space left by the wax, usually just a few millimetres, then the allow cools and hardens the bronze cast has been accomplished.
The most frequently used bronze alloy is composed of copper and tin.
It allows for a thin and regular surface. After the casting it is necessary to free the sculpture from a lot of outer drippings and to finish and to chisel the surfaces.
At last, through oxidation and thermal treatment, the bronze receives the desired patina.
Salvadori Arte is the last heir of Pistoia's great metallurgical tradition, which started in the eleventh century and reached its greatest splendour in the first decades to the twentieth century when the Lippi and Michelucci foundries were still active.
