12PK Coarse White Marble Metamorphic Rock Specimens - Approx. 1" - Geologist Selected and Hand Processed - Great for Science Classrooms - Class Pack - Eisco Labs

Coarse White Marble SpecimenSet of 12 Samples, 1"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 buildings 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. While each specimen will vary slightly in shape, size and color, it will measure approximately 1" in length. Specimens are packaged, labeled & barcoded for easy identification and storage. Selected & Processed by a Geologist.Each and every specimen is selected and hand processed by an actual geologist, ensuring that each sample exhibits defining features. Rocks and minerals are sourced from a variety of locations around the world and are processed by hand in Victor, NY.
