Materials and construction
Makers fashioned these works using natural stone foundations paired with cast metal figures. Sculptors utilised bronze and spelter for the upper subjects, applying cold-painted enamels to render details on dancers and animal studies.
The stone was cut, shaped, and polished to form square or irregular plinths designed to receive threaded metal pins projecting from the feet or base of the mounted figures.

The Green Onyx Base Glossary
- Cold-painted bronze
- Metal sculpture painted with oil-based or enamel paints that are not subjected to kiln firing. This technique allowed makers to achieve lifelike polychrome finishes on dancers and animals.
- Spelter
- A zinc alloy frequently utilised as a less costly alternative to bronze for figurative castings. It often received copper or bronze-toned plating to simulate more expensive metals.
- Garniture set
- A coordinated arrangement of ornamental objects, typically comprising a central clock flanked by matching side ornaments on matching bases. These decorative sets dominated grand interior mantelpieces during the Victorian era.
- Art Deco
- A design style emerging in the interwar years characterised by sleek geometric forms and stylized depictions of the human figure. It heavily influenced European sculpture and metalwork during the 1920s and 1930s.
