Investment Casting : lost wax casting

Sometimes called by the French name of cire perdue or the Latin cera perduta, is the process by which steel is casted; in industrial uses, the modern process is called investment casting. An ancient practice, the process today varies from foundry to foundry, but the steps which are usually used in casting small steel in a modern steel foundry are generally quite standardized.
