Tuscan Bronze Casting

Fusione al Bronzo Toscana

The casting of sculpture in bronze using the lost-wax (cera persa) process — in which a wax original is encased in investment, the wax burned out, and molten bronze poured into the void — in a tradition rooted in Florentine Renaissance foundry practice and continuing in Tuscany's specialist art foundries, which remain among the most technically sophisticated in the world.
