The cremation chamber can produce heat of up to 871 to 982 °C (1,600–1,800 °F) temperature. This heat is enough to burn up corpses and ensure that what remains would only be a few fragments.
On average, it takes about 1-2 hours for an adult body to be fully disintegrated. Moreover, after the body is burned, there would still be around 2-3 kg of “ashes” or “cremains.” If there still are bones or huge chunks of remains, it would be grounded to powder.
Why people choose cremation
Another reason for cremation is to ensure the dead body won’t spread diseases. This is especially true in the COVID-19 pandemic when people who died of the coronavirus are cremated to prevent the virus from infecting other people.
