Jewellery BoxJewellery casting is the method of creating jewellery pieces. The method involves pouring some liquid metal alloy on a mould. Industry expert JewelCast Ltd typically call it low-cost casting for they make the casting mould using a wax mould that they melt away. This then leaves a hollow chamber in the centre of the mould. Do you want to create your own jewellery using the casting method (or just want to learn more about jewellery making in general)? Here is how jewellery makers make the most intricate pieces:

Melting

Put the metal that you chose to make the jewellery in a pouring crucible before melting it in a foundry. Take note that the time and melting temperature will depend on the kind of metal you will use. You can even use a small crucible and blow-torch to melt silver.

Casting

Use a centrifugal casting machine to transfer metal onto the mould. Those who want to produce professionally made jewellery will require a centrifuge. This device distributes metal more quickly and evenly. But you also have other options for casting. Those who prefer the easier and standard solution can just pour the metal carefully into the tunnel from the base of the mould.

Moulding

To pump the metal to the mould, use a large metal-particular syringe. Let the metal cool for around 5–10 minutes before slowly dunking it in cold water. The duration it takes for the metal to cool will depend on the metal that you used and melted. Be cautious about this step for dunking it early will cause the metal to crack. Meanwhile, dunking it too late will make it difficult for you to get rid of the plaster from the hardened metal.

Cooling

At this point, the plaster should start to dissolve away while you are shaking it in cold water. Gently tap the mould with a hammer to reveal the jewellery and remove the excess plaster. Separate the sprue base from the flask. Then, use an old toothbrush or your fingers to remove the bits that are still sticking to the jewellery.

For thousands of years, both home crafters and master artisans use this process to create original jewellery pieces. This is the process used by the most seasoned veterans in the industry, which you can learn from.
