What is cast bronze?

Cast bronze refers to the process of creating objects by pouring molten bronze into a mold and allowing it to cool and solidify. This method is widely used in sculpture and various metalwork applications because it allows for detailed and intricate designs to be achieved. The process typically involves heating bronze until it reaches a molten state, after which it is poured into a pre-shaped mold. Once the metal cools and hardens, it takes on the form of the mold, enabling the creation of complex shapes and detailed textures.

In contrast, while bronze is indeed a type of metal alloy—primarily composed of copper and tin—the definition of cast bronze specifically pertains to the casting process rather than the material itself. The options related to decorative features on caskets or finishing processes do not accurately capture the fundamental attributes and definition of cast bronze as a technique used in metalworking and sculpture.
