design and production

A detailed wax model of the final object is sculpted. This model represents the exact size and shape of the item to be cast in metal.

The wax model is coated with a ceramic or plaster material, known as the "investment." This forms a mold around the wax. Once the investment material hardens, it creates a mold that can withstand high temperatures.

The mold is then heated, and the wax inside is melted and drained away, leaving a hollow cavity in the shape of the wax model. This step is why it's called "lost wax" casting—the wax is lost in the process.

Molten metal, such as gold, silver, bronze, or another material, is poured into the mold cavity where the wax used to be.

After the metal cools and solidifies, the ceramic or plaster mold is broken away, revealing the metal object inside.

The metal casting is then cleaned, polished, and any final details or adjustments are made, like setting stones or adding patinas.
