Silicone mold for metal casting

Why silicone is the material of choice for creative artists

Art foundry is a technique used to mold sculptures, usually through the use of lost-wax casting. This centuries-old method, also known as cire-perdue, involves pouring molten metal into a mold that has been created by means of a model. A first mold is made by silicone and is filled with wax. The wax model is coated with a refractory to form a second mold. Wax melts away and is replaced by the metal. Different materials can be used to create the model, such as tallow, tar, resins. Artists work with a multitude of final materials such as aluminum, bronze, or other ferrous and non-ferrous metals.  Gold and silver are also used for smaller pieces, in particular in jewelry.  Craftsmen choose these metals for artistic reasons, but also for the compatibility between the different materials and the casting methods they use. Silicone has become one of the preferred materials for creating lost-wax casting models because it is versatile, resistant, easy to use and capable of reproducing the finest details of the original.
