What does the lost-wax process involve?

The lost-wax process is a method of metal casting that involves creating a model of the desired object in wax, which is then encased in a mold. The mold is heated, causing the wax to melt and flow out, hence the term "lost wax." Once the wax is removed, molten metal is poured into the mold to create the desired shape. This technique allows for a high level of detail and is commonly used for creating sculptures and intricate metal objects. The other options do not pertain to the lost-wax process; they describe different techniques related to pottery and sculpture making but do not involve metal casting through wax molds.
