M ummification is the preservation of a body, either animal or human.
Some mummies are preserved wet, some are frozen, and some are dried.
It can be a natural process or it may be deliberately achieved. The Egyptian mummies were deliberately made by drying the body. By eliminating moisture, you have eliminated the source of decay. They dried the body by using a salt mixture called natron. Natron is a natural substance that is found in abundance along the Nile river.
