The design process
Each piece is one of a kind, created by hand and goes through a four stage process.
Handmade work, with its inherent imperfections, carries a unique charm that mass-produced items can't replicate. These small variations are a testament to the craftsmanship, creativity, and the human touch that go into every piece. Rather than detracting from its value, imperfections in handmade work add character and individuality, making each item one-of-a-kind.
The casting process
Lost wax casting, also known as investment casting, is an ancient method used to create metal objects from a wax model. The process involves several steps:
Creating the Wax Model

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.
Making the Mold

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.
Burning Out the Wax

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.
Pouring the Metal

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

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.
