EISCO Coarse White Marble Specimen Metamorphic Rock Approx 1 3cm

Marble is a metamorphic rock formed from limestone. The high-pressure, low-heat alteration leads to a massive crystalline rock that can form a variety of shapes. Marble is mined heavily for use in building and furniture, and has traditionally been used in architecture as well. Though much denser than limestone, marble will still effervesce in acid, making it useful in identification exercises. This sample is also available in packs of 12.
