Sanitary Silicone Used to Make Small Art Cast Parts

Abstract

Also known as investment or precision casting process, the “lost wax process” was used in ancient times from China to Egypt to cast exquisite objects which are now displayed as artifacts in museums. The process is called “lost wax” because the wax is lost or burned off in the process. The process starts with the making of a rubber mould of an original piece. The rubber mould is then used to create wax duplicates of the original piece. The mould making process is an art in itself and requires a skilled craftsman to create a good long lasting mould. The paper presents the use of “sanitary silicone” to make “rubber mould”.
