Historical Production
Traditionally, lye was produced by pouring water through wood ashes as part of the soap-making process.
Features
Lye is a white, solid material that can be broken down into flakes, pellets or powder. It is hygroscopic, meaning it absorbs moisture from the air, and exothermic when dissolved in water, meaning it can produce heat.
Common Uses
Crafters still use lye for soap-making, and it also is found in chemical cleaning products such as drain cleaners. Food-grade lye is used to cure olives and lutefisk.
Protection
Use gloves, safety glasses and face masks when handling lye, and work with it in a well-ventilated area.
Warning
Lye is corrosive and can damage the eyes and skin. It is deadly if ingested in sufficient quantities. When lye is mixed with sugar, it produces carbon monoxide, a potentially fatal gas.
