The regulated process of reducing human remains to bone fragments (i e "ashes") through intense heat and evaporation in a cremation chamber The building which houses cremation chambers is called a crematory Generally, it takes 2 hours to cremate human remains, with the cremated remains usually weighing 4-8 pounds
Disposing of a corpse by burning. In the ancient world cremation took place on an open pyre. It was practiced by the Greeks (who considered it suitable for heroes and war dead) and the Romans (among whom it became a status symbol). The pagan Scandinavians also cremated their dead. In India the custom is very ancient. In some Asian countries only certain people may be cremated (e.g., high lamas in Tibet). Christianity opposed cremation, and it became rare in Europe after AD 1000 except under extreme circumstances, such as that brought on by the Black Death. The practice reemerged in the late 19th century and was eventually accepted by both Protestants and Roman Catholics
