Marble is a metamorphic rock consisting of carbonate minerals (most commonly calcite (CaCO 3) or dolomite (CaMg (CO 3) 2) that have recrystallized under the influence of heat and pressure. [1] It has a crystalline texture, and is typically not foliated (layered), although there are exceptions. In geology, the term marble refers to metamorphosed ...
Carrara marble, or Luna marble (marmor lunense) to the Romans, is a type of white or blue-grey marble popular for use in sculpture and building decor. It has been quarried since Roman times in the mountains just outside the city of Carrara in the province of Massa and Carrara in the Lunigiana , the northernmost tip of modern-day Tuscany , Italy.

Marble from Fauske Municipality in Norway Blocks of Carrara marble in Italy. The following is a list of various types of marble according to location. (NB: Marble-like stone which is not true marble according to geologists is included, but is indicated by italics with geologic classification given as footnote.
Quartz. Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The atoms are linked in a continuous framework of SiO 4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO 2. Quartz is, therefore, classified structurally as a framework silicate mineral ...
A poultice is a thick paste, usually made from baking soda and water. When applied and left to set, it will typically pull the stain out of the marble in a non-abrasive manner, Cohoon explains.
Stucco marble was an artificial marble made using gypsum (sometimes with lime), pigments, water and glue. Stucco lustro was another a form of imitation marble (sometimes called stucco lucido) where a thin layer of lime or gypsum plaster was applied over a scored support of lime, with pigments scattered on surface of the wet plaster.
A mix of marble or quartz powder, resin, and pigment is cast using vacuum oscillation to form blocks. Slabs are then produced by cutting, grinding, and polishing. Some factories have developed a special, low-viscosity, high-strength polyester resin to improve hardness, strength, and gloss and to reduce water absorption.
