Limestone can also be chemical in origin as is the case with travertine. Chemical limestone forms when calcium and carbonate ions suspended in water chemically bond and precipitate from their aquatic sources. Because of its high calcium content, limestone is usually light in color, although many variations exist.

By adding water to quicklime you will produce a suspension of calcium hydroxide particles through an exothermic reaction known as lime slaking (more below). This suspension is what we refer to as lime slurry, also known as milk of lime or limewater. Lime slurry is the form of lime most often added to water and wastewater treatment processes.
