Limestone, a naturally existing stone, is found in all continents of the earth. Limestone’s soft, earthy tones give designers great flexibility in selecting complimentary colors for other interior elements. Despite the common and traditional reference to “travertine marble”, travertine is really a type of limestone. It is actually the terrestrial (land) formed version of limestone, as opposed to the marine-based formations of many other limestone varieties.
Dolomite is another form of limestone. Dolomite is based on the dual carbonate of calcium-magnesium carbonate, and the properties of this stone are influenced by this difference in composition. Dolomite generally has a higher density, lower absorption, greater compressive and bending strength, and higher abrasion resistance than the calcium carbonate-based limestones. These property differences offer some application choices for dolomites where other limestone varieties are marginal or unsuitable performers.
Many varieties of both materials have enjoyed a successful history of exterior application, and some of the most prominent government and financial institutions worldwide proudly display limestone as their exterior cladding.
Since these stones are some of the softer varieties of natural stone materials, they have long been a popular choice for intricately carved features and moldings.
