In one of her novels, Jean Auel described how ancient cultures made
lye soap. They mixed animal fat with an alkali solution, which they made
by adding water to wood ashes. There was more to the process than that,
but I remember reading that the pH of the alkali solution was so high,
it could burn the skin.
