What is casting in jewelry making?

Jewelry casting is the process by which a wax pattern is made into a jewelry mold and then filled with molten metal (Gold, silver, brass, platinum )  to create a piece of jewelry. The wax is always “lost” during jewelry making. That’s why it is also called lost wax casting.
Most jewelry casting is done through the lost wax process, whereby models created through wax carving, growing, or printing are encased in a plaster-like medium known as investment. The investment is heated to extreme temperatures to incinerate the material, creating an impression of the desired form.
