In hollow casting, what happens to the wax mold during the process?

In the hollow casting process, the wax mold plays a crucial role as a temporary material that shapes the final product. During the casting process, the wax mold is subjected to heat. As a result, it melts away, leaving a hollow cavity that will ultimately be filled with molten metal. This step is essential for creating the desired shape of the final object, as the wax is designed to be a disposable material that provides a precise form but can be easily removed through melting. The technique is often associated with lost-wax casting, where the focus is on achieving intricate and detailed designs in metalwork.
