How silicone is used in the jewelry lost wax casting process

Lost-wax casting has been used for thousands of years to reproduce original jewelry pieces. This process, used by master craftsmen as well as home crafters, involves pouring a liquid metal alloy into a mold, using a wax model that melts away to leave a hollow chamber in the mold. High-precision silicones provide the best reproduction fidelity for jewelry making in this process because of their flexibility and unique mechanical properties.

Elkem Silicones has a long history in designing and making silicones. We have developed a full range of RTV2 rubber elastomer products with all the essential properties to make accurate molds for jewelry casting. These easy-to-use products provide strength, dimensional stability and excellent fluidity, thus giving creators the freedom to design and make the finest jewelry with practically every metal alloy.

Our specialist teams are available to work with you, whether you are a master craftsman, a fashion designer or a teacher, to help you find the right silicone art products to make the jewels of your dreams.
