Microfusion

La microfusionalso known as lost wax castingis a sophisticated and precise method used in the luxury jewellery. Originating from techniques that go back thousands of years, microfusion enables jewellery pieces of exceptional complexity and finesse to be created. This technique is particularly popular for the creation of jewellery in gold, silver, platinum and other precious metals, often adorned with precious stones.

The microfusion process

The microfusion process involves a number of meticulous steps to ensure impeccable results.

1. Creating the wax model The first step is to sculpt a wax model of the piece to be created. This stage requires great precision, as the wax model will be reproduced identically in the precious metal.
2. Embedding the model Once the wax model is complete, it is encased in a refractory ceramic. This ceramic forms a solid mould that can withstand the high temperatures of casting.
3. Wax casting The ceramic mould is then heated to melt and evacuate the wax, leaving an empty cavity that perfectly reproduces the shape of the original model.
4. Metal injection The precious metal is melted and injected into the cavity left by the wax. Once the metal has cooled and solidified, it takes on the exact shape of the original wax model.
5. Finish The final stage involves breaking the ceramic mould to recover the metal piece. This is then cleaned, polished and, if necessary, set with precious stones to create the final piece of jewellery.

Advantages of microfusion

La microfusion offers a number of advantages that make it the technique of choice for luxury jewellery :

• Precision and detail Microfusion enables jewellery to be created with an unrivalled level of detail and finesse, making it possible to create complex patterns and innovative designs.
• Flexibility This technique is extremely flexible, allowing the use of various precious metals and the incorporation of precious stones of different shapes and sizes.
• Reproducibility Once the wax model has been made, it is possible to produce several copies of the same piece of jewellery with identical precision, which is ideal for luxury jewellery collections in limited series.
