Cremation: Burning a house to hide a body is almost always unsuccessful. Most house fires burn on average at 1100°F (593°C) for 27 min. This is not hot enough or long enough to cremate a human body. For that, fires must be1400–1800°F (760–982°C) for 3 hours.
Accelerants: Common household products can be used as accelerants, for example, gasoline, paint thinners, camping stove fuel, and ethyl alcohol.
