What is a key feature of the hollow casting method?

The hollow casting method is characterized by its use of a wax mold to create hollow objects. This technique typically involves a process known as lost-wax casting, where a model is first made in wax, which is then encased in a material that hardens to form a mold. Once the mold is ready, the wax is heated and removed, leaving a hollow cavity into which molten metal can be poured. This casting method is advantageous because it allows for the creation of intricate and lightweight structures as well as the ability to produce multiple copies of the same object.

In contrast to other methods, such as firing solid metal, which does not create hollow forms, or requiring a single pour technique which could limit the shape and complexity of the produced piece, the hollow casting process emphasizes the creation of hollow objects, offering versatility in design and application. Additionally, while hollow casting can be used for sculpture, it is not limited to this medium and can be applicable in various artistic and functional contexts.
