Blog 2: What exactly is lost wax casting?

The lost wax casting process is an ancient technique used to create jewelry. It’s also known as investment casting. You start with a wax model and attach it to the “tree”. This is also called a sprue, which is basically a branch attaching the ring or pendant to the tree. The investment solution is poured in making a mold around the tree. After the solution has hardened, the wax is melted out of the mold. The next step involves melting metal into liquid form and then pouring it into the mold. Once that process is complete, you start sanding the piece where it attached to the tree to make it smooth.
