Behind The Bench: Jewellery Casting Process

Often people are shocked when I try to explain lost wax casting, as it's a bizarre concept. But it's a pretty old technique though the technology has changed over the centuries!

Dating back to the 3rd century BC, this method has stood the test of time, offering a magical way to craft stunning metal pieces. and many of the techniques stayed the same!

The process starts with creating a model using jewellers carving wax.

Then, I make a wax "tree" with a center sprue of wax, which is put into a frame that liquid plaster is poured over it. The plaster mold is put into a kiln overnight to bake and the wax melts out of the plaster mold leaving a void behind where the wax once was.

Using either centrifuge casting or vacuum casting, molten metal is poured into it.

As the metal cools, it takes on the shape of that wax model, transforming into gorgeous jewellery like in the photo of the silver casting tree. But here's the twist—this method isn't limited to just jewellery. It was once used for sculptures and ornaments too!

The beauty of lost wax casting? You can replicate the same design as many times as you'd like, making it perfect for crafting collections or multiple pieces for sale. Plus, there's a variety of metals at your disposal—think silver, gold, brass, and bronze—for endless creative possibilities.

Tell me what you think, and if you have more questions about the process!
