The cremated remains of an adult female usually weigh around 4 pounds, while the remains of an adult male weigh around 6 pounds. These numbers can vary significantly depending on the height and bone structure of the individual.
Cremation typically occurs at a temperature of between 1,500 and 1,900 degrees Fahrenheit and takes two to three hours to complete. During this time, all of the water and virtually all of the tissues of the body are completely vaporized. Typically, all that remains are bones and some traces of mineral salts. The bones begin to flake and crumble under the intense heat, but many bone pieces remain after cremation. These fragments are ground up until they reach the consistency of coarse sand.
