Special alloys and treatments
Patination is a process obtained from chemical reactions directly on the bronze, but there are also available other treatments:
gold-leafing when 24K pure gold-leaves are applied to the sculpture’s surface; the gilding, silver-plating and nickel-plating by immersion in a galvanic bath. With the ‘leaf’ method, platinum and palladium leaves can also be applied.
Apart from these treatments, other types of alloy can be used to obtain diverse effects: for example, aluminium and nickel silver; recently, the Foundry has perfected a new metal alloy i.e. white bronze.
The casting for these special alloys takes place by following the same procedure, illustrated above, as for bronze.
