What is Quicklime ?
Quicklime, more formally known as calcium oxide (CaO), is a caustic alkaline substance which is produced by heating limestone in specially designed kilns. There are a wide range of uses for quicklime, ranging from mortar to flux, and the substance has been used by humans for centuries. Many companies produce and sell quicklime, sometimes with specific chemical impurities which make it especially suitable to certain applications. Humans have been aware of the steps needed to create quicklime for a very long time, and chemists believe that the generation of quicklime may be one of the oldest chemical reactions known to man. People have certainly been using quicklime all over the world for thousands of years; in Mesoamerica, for example, people treated corn with quicklime in a process known as nixtamalization, while in India quicklime was used in a mixture designed to waterproof boats. Today, quicklime is used in many industrial processes, some of which were developed hundreds of years ag
