Lime made from a Seashell

A seashell was heated in a lime kiln to convert the shell material into lime. Limelight also known as calcium light is a type of stage lighting once used in theaters. A bright light is created when a sample of quicklime (calcium oxide). The light is produced by incandescence. The historic use of the light still services as someone in the public eye is still said to be ?in the limelight.? .Lime is produced by heating calcium carbonate until the extra carbon and oxygen atoms are driven off leaving just the calcium oxide. This process is very easy and takes place in a lime kiln. Lime can be made from sea shells, chalk, and many types of rock - including marble.
