How do I clean a bronze animal?

Dust the surface gently with a soft, dry brush to prevent dirt from accumulating in the crevices of the metal. Avoid using chemical polishes, as these can strip away the historical patina that accumulates over decades. Apply a very light coat of microcrystalline wax occasionally if the bronze appears dry. Buff gently with a clean cloth to restore a soft, protective sheen.

What is cold-painted bronze?

Cold-painted bronze refers to metal sculptures finished with oil or varnish-based paints applied without heat firing. This technique was widely utilised by Viennese workshops to create brightly coloured birds, dogs and human figures. Because the paint sits on the metal rather than fusing with it, these pieces require careful handling to prevent chipping. The presence of original paint significantly influences the character of the object.

Are these pieces solid bronze?

Many sculptures are cast using the lost-wax method to create solid or heavy hollow metal forms. Some contemporary or alternative pieces utilise spelter, which is a lighter zinc-based metal given a bronze-like finish. Checking the weight and examining the underside can help distinguish solid bronze from alloy substitutes. Bronze develops a deep, stable oxidation over time, unlike softer metals.

How are marble bases dated?

Marble and onyx bases reflect the prevailing design aesthetics of their production era, such as the geometric cuts popular in Art Deco pieces. The thickness of the stone, the type of polish and the mounting screws underneath offer clues to the period. Early pieces often feature hand-finished marble plinths tailored individually to the sculpture's feet. Later mass-produced items tended to use standardised rectangular slabs.
