In the first ten minutes of the cremation, the flames attack the body’s soft tissue—all the squishy parts, if you will. Muscles, skin, organs, and fat sizzle, shrink, and evaporate. The bones of the skull and ribs start to emerge. The top of the skull pops off and the blackened brain gets zapped away by the flames. The human body is roughly 60 percent water, and that H2O—along with other body fluids—evaporates right up the machine’s chimney.
