Limestone is a rock that is formed chiefly by accumulation of organic remains (as shells or coral), consists mainly of calcium carbonated, and is extensively used in building. Mainly consists of calcite. It does not show much graining or crystalline structure. It has a smooth granular surface. Varies in hardness. Some dense limestones can be polished. Common colors are black, grey, white, yellow or brown. It is more likely to stain than marble. Limestone is known to contain lime from sea water.Limestone, molded from rock, faithfuly reproduces the unique character of nature's array of blue-veined, white-veined and unveined colors. This broad selection of coursed and roughly squared stones allow the designer unusual flexibilty.


Typical finishes for limestone are:

Polished: glossy surface which brings out the full color and character of the limestone.

Honed: (a satin smooth surface with little or no gloss).

Sawn: (a comparatively rough surface; can be chat, shot, sand or diamond sawn).


Other Finishes:

Sand Blasted: matte textured surface finish with no gloss; finished by application of a steady flow of sand and water pleasure.

Bush-Hammered: a mechanical process which produces textured surface; textures vary from subtle to rough.


Precautions for Limestone:

-Do NOT use scouring powders or creams; these products contain abrasives that may scratch the surface.

-Do NOT use cleaning products that contain lemon, vinegar or other acids.

-Use coasters under all glasses, particularly those containing alcohol or citrus juices. Many common foods and drinks contain acids that may etch or dull the stone surface.

-Do NOT place hot items directly on the stone surface. Use trivets or mats under hot dishes and placemats under china, ceramics, silver or other objects that can scratch the surface.
