Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Marble is typically not foliated (layered), although there are exceptions. In geology, the term marble refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is commonly used for sculpture and as a building material.
In the industrial context, marble is a type of natural stone that is commonly used in building and construction, as well as in the production of various products. Marble is a metamorphic rock that is composed primarily of calcite or dolomite minerals, and it has a distinctive appearance characterized by its swirled and veined patterns.
Examples of industrial applications of marble include:
Building and construction: Marble is commonly used as a decorative material in buildings, particularly for flooring, countertops, and walls. It is valued for its unique appearance, durability, and resistance to heat and moisture.
Sculpture: Marble has been used for centuries as a medium for creating works of art and sculpture. It is relatively soft and easy to carve, and its unique patterns and colors make it a popular choice among artists.
Paper production: Ground-up marble is sometimes used as a filler material in paper production, as it can improve the opacity, brightness, and smoothness of the finished paper.
Cosmetics and personal care products: Marble powder is sometimes used as an ingredient in cosmetics and personal care products, particularly as a gentle exfoliating agent.
Pharmaceuticals: Marble is sometimes used as a source of calcium carbonate, which is a common ingredient in antacids and other pharmaceutical products.
Similar materials to marble include other types of natural stone such as granite, limestone, and sandstone, as well as engineered stone products like quartz and terrazzo.
