At Aisha Mystic Jewelers, one of the methods we use to create jewelry is called lost wax investment casting. Regarded as one of the oldest manufacturing processes, archeologists have found lost wax casting was used for jewelry making and sculpting created dating back up to 5,000 years.
Due to its versatility and simplicity, lost wax investment casting has effortlessly adapted to modern technology. Depending on the talent of the jewelry manufacturer and the quality of the wax, mold, and metal, pieces can be extremely intricate and delicate.
Given the wide range of techniques used to create wax models, there are several kinds of wax that can be used in lost wax jewelry casting, each one appropriate for the different demands of a design.
When lost wax investment casting manufacturers create a model by hand, a soft wax, like microcrystalline wax, can be applied using small, individual lumps. To warm the wax, place it near a light bulb, in warm water, in the sun, or use a torch to heat the surface and scrape off the warmed wax.
