The casket or container is placed in the cremation chamber, where the temperature is raised to approximately 1400 to 1800 degrees Fahrenheit. After approximately 2 to 2 1/2 hours, all organic matter is consumed by heat or evaporation. The remaining bone fragments are known as cremated remains (or cremains). The cremated remains are then carefully removed from the cremation chamber. Any metal is removed with a magnet and later disposed of in an approved manner. The cremated remains are then processed into fine particles and are placed in a temporary container provided by the crematory or placed in an urn purchased by the family. The entire process takes approximately four hours. Throughout the cremation process, a carefully controlled labeling system ensures correct identification.
