Lost wax casting or microfusione: a specific technique used to carefully reproduce uneasy metal parts, even very small. The original model is faithfully copied with silicone elastic material and then it is reproduced in wax. This copies in wax (positive reproduction of the original one) will be coated with special ceramics. These moulds will be cooked for many hours so the wax will flow out allowing the fused brass to fill them.
The chandeller, which weights 2.332 oz, was commissioned by James Hamilton, 2nd Marquess of Abercom (1811-85), who succeeded to the title in 1833 and was created Duke of Abercom in 1868. He also bought extensively from Storr & Mortimer.
