A seashell was heated in a lime kiln to convert the shell material into lime. Lime is produced by heating calcium carbonate until the extra carbon and oxygen atoms are driven off,leaving just the calcium oxide,or quicklime,which is used to make limelight (a historic type of stage lighting and source of the phrase 'in the limelight'). Lime can be made from marble,chalk,and many types of rock,even from seashells | |
