Introduction to Lye

Lye, as a chemical compound, primarily refers to sodium hydroxide (NaOH) or potassium hydroxide (KOH), both of which are highly caustic bases and alkali that react strongly with water. Historically, it has been used in various industries and domestic settings, ranging from soap making to food preparation. The design purpose of Lye, in the context of this specialized GPT, is to elucidate the chemical nature, applications, safety precautions, and the broad utility of lye in a variety of contexts. For instance, in soap making, lye reacts with fats and oils in a process called saponification to produce soap, showcasing its role in transforming raw materials into products beneficial for hygiene and health. Another scenario involves its use in the food industry, where lye is used in curing olives or making traditional pretzels, demonstrating its versatility and the importance of understanding its properties and handling guidelines to safely utilize its benefits.
