Lime in the form of stone is the fifth most abundant element in the world's crust.

Limestone/chalk forms approximately 20% of the world's sedimentary rock. As early as the fourth millennium BC quicklime was used as building material and through history its range of uses has broadened.

Lime is a generic term that is used to refer to the processed products from burning limestone or chalk.

The burned limestone or chalk straight from the kiln has undergone a process known as calcining and is known as quicklime and when water is added, also known as slaking, the quicklime becomes hydrated lime or slaked lime.

Computer controlled production processes within the kilns and in the slaking and conditioning methods create a wide range of lime-based products with specific characteristics developed for particular applications.
