How hot are the flames used in cremation for human bodies in the U.S.?
In the United States, different states have enacted laws that require certain temperatures, but the range is typically between 1400 and 1600 degrees Fahrenheit. Cremation is the process of combusting a human body into particles of inorganic matter, which settle in the bottom of the cremation chamber, and gasses which are released through a smokestack. This process can take between 30 minutes and two hours depending on the size of the body.
