Lye is Sodium Hydroxide, NaOH. A very strong base and very dangerous because it can cause severe chemical burns. Definitely has to be handled with care. But it is sold at most hardware stores as a drain cleaner (for soapmaking, you must be sure the container says 100% NaOH). Lye is necessary for the chemical reaction that turns fats into soap.
