How Much of the Body Remains After Cremation
Cremation isn’t like a campfire that leaves you with a neat heap of ash and some charred marshmallows. The human body is about 60% water, and that water has got to go somewhere. During cremation, a furnace cranks up to around 1,600 to 1,800 degrees Fahrenheit—hot enough to vaporize almost everything that holds you together.
Your soft tissues, organs, and even your DNA are completely destroyed by the heat. Think of it as a rapid, extreme version of what happens to a log in a bonfire: the water and carbon burn off, leaving only the mineral skeleton behind. So, the real question is: what happens to your bones?
