Marble is geologically classified as a metamorphic rock. Marble can also be formed through recrystallization. Limestone, which is a sedimentary stone, recrystallizes under pressure, heat and time to form marble. The metamorphic marbles that are formed under higher pressure are denser and more fracture-free than recrystallized marbles. Marble consists mainly of recrystallized calcite and/or dolomite. Calcilite has a wide range of colors from black to white and from transparent to clear. Other colors are caused by the introduction of minor amounts of substances during the formation of the stone. Iron oxides make the pinks, yellows, browns, and reds. Most grays, blue grays, and blacks are of bituminous origin. Mica, chlorites and silicates cause greens.

Marble comes in four grades: A, B, C, and D. Grades A and B are the only grades Premier Surfaces would consider using. Grade A is a completely metamorphosed limestone base, with no geological voids or flaws. Grade B is similar to A but may contain voids or flaws that are easily filled with a polyester or acrylic filler. The other two grades have considerable more voids and cannot be brought up to the quality level Premier Surfaces wants to offer to the customer.

The mineralogical makeup of marble makes it vulnerable to abrasion and chemical attack. Ordinary kitchen utensils can scratch the surface of marble and acid in juices such as vinegar, tomato, lemon or other fruit juices can stain the surface of marble primarily due to its calcium carbonate base. Care must be exercised to protect marble surfaces from damage. Premier Surfaces does not recommend Marble for use as a kitchen countertop. Marble is best used in bathroom countertops or for display pieces.
