polski), also known as burnt lime or calcium oxide (CaO), is a caustic alkaline substance that has been used in various forms throughout history.
Etymology
The term "quicklime" comes from the Old English "cwic", meaning "living", and "lime", derived from the Latin "limus", meaning "slime". The term "quick" was used in this context to mean "active" or "lively", referring to the vigorous reaction of quicklime when combined with water.
Production
Quicklime is produced by heating limestone (calcium carbonate) in a process known as calcination, which drives off carbon dioxide and leaves behind calcium oxide.
Uses
Historically, quicklime was used in the mortar used in building construction. Today, it is used in a wide range of industrial applications, including the production of cement, the treatment of drinking water, and the manufacture of glass and steel.
