What is the chemical used for preservation during mummification?

Natron is a naturally occurring product frequently harvested from lake beds. It was used by the Egyptians to dry out the bodies of the deceased in an elaborate mummification process. It is a mixture of sodium carbonate and sodium bicarbonate, and can vary in color from white to gray or yellow depending on its purity.

Hope this helps!
