Jewelry Casting Secrets

As a jeweler, I feel the need to share my knowledge and the secrets of jewelry casting. Below, I’ll briefly describe the stages of the process, because behind every magic there is toil.

The first step is to create a successful prototype (“model”). The model can be carved via lost wax casting or 3D printing. Afterwards, the model – for example, a ring – is taken to a foundry, where workers are required to have an expertise of their own.

In the foundry, they take the ring and attach a long, thin rod to it, which is also made of wax. Then, the ring with the rod are buried together in a special cast, while the rod remaining outside the cast.

After placing the model in the cast, the whole package is put in a special oven that burns the cast and the wax inside it, the rod and the model overnight. The wax burns and disappears completely in this process, hence it is called “lost wax casting”.

After burning, the cast cylinder remains in one piece, but with a hole leading to the ring inside the cast (where the rod was placed), and a cavity inside the cast that copies the ring perfectly. Now we have a new mold of our jewel.

The next step is to dissolve the metal we want to use – gold or silver – into liquid, and pour the metal from the hole into the cavity. At the foundry, they use dedicated metal casting machines with rapid rotation and gravity utilization abilities.

Following metal casting, we have a cast cylinder filled with the selected metal. Now, we should put it into water (this is my favorite part, because of all the tiny noises and explosion sounds…).

The cast cylinder crumbles and what is left is our metal ring, with the thin rod on it, only that this time it also became metal. Now it’s time to remove the rod with a cutter and polish our ring. Voila! A new piece of jewelry is born!

The next and final step is jewelry duplication.

To duplicate a finalized piece of metal jewelry, we would have to use the services of a professional foundry yet again, where they would create a rubber mold for the ring, designed for material injections. The “lost wax” can be injected into the mold over and over, thus creating endless wax models that can be used in the above process for casting any quantity of jewelry we want.
