What happens to the wax mold in the lost-wax metal casting process?

In the lost-wax metal casting process, the wax mold is melted away to create space for the molten metal that will be poured into the mold. This technique begins with a model made of wax that is coated with a ceramic shell. When the mold is heated, the wax melts and drains out, leaving a detailed cavity in the shape of the original wax model. Once this is done, molten metal can then be introduced into the cavity to create the final piece. This process allows for intricate designs and is commonly used for sculptures and jewelry-making. The melting away of the wax is integral to the process, as it enables the precise replication of the artist's original design without any of the wax being retained in the final product.
