Marble

General Characteristics: Marble is a crystalline, compact variety of metamorphosed limestone, consisting primarily of calcite (CaCO3), dolomite (CaMg (CO3) 2), or a combination of both minerals. Pure calcite is white, but mineral impurities add color in variegated patterns. Commercially the term marble is extended to include any rock composed of calcium carbonate that takes a polish, and it includes some ordinary limestones. The surface of marble is durable in a dry atmosphere and when protected from rain. Marble can be successfully used for all low traffic in-house application like vanities and fireplaces or walls. It is favorable stone for it’s beauty and design but it is softer than granite and less challenging for breaking, acids and liquid absorption. Again, stone sealer/impregnators should be used.
