How do I clean a patinated bronze?

Dust the sculpture gently with a soft, dry brush to prevent particle buildup in the recessed areas. Avoid water, soap or metal polishes that strip the chemical patina from the surface. Apply a very thin coat of microcrystalline wax if the metal appears dry. Buff it off immediately with a clean flannel cloth to restore a soft, protective sheen.

What is the difference between bronze and ormolu?

Bronze is an alloy of copper and tin used to cast the core sculptural form. It typically receives a chemical patination to produce dark brown or green surface tones. Ormolu refers to gilded bronze where gold is applied to the metal surface. This creates a bright, reflective golden finish rather than a dark metallic patina.

Are these sculptures solid metal?

Most antique tabletop bronzes are hollow casts rather than solid metal blocks. Hollow casting saved expensive metal and reduced the overall weight of the decorative object. Foundries used an internal core material during the casting process which sometimes remains visible inside the base. The thickness of the metal wall depends on the scale and foundry practice.

Why do some bronzes have marble bases?

Marble bases provided visual weight and stability to slender or top-heavy figures. They also offered a clean architectural platform that contrasted with the dark patinated metal. Makers selected different marbles, such as white or veined varieties, to complement the style of the sculpture and its period.
