Product Overview
Calcite is made up of calcium carbonate. It can grow into rocks, animal shells, chalk, & translucent, rhombic minerals. Being one of just a few minerals that is effervesce in acid, Calcite is great for demonstrating chemical reactions. This universally useful mineral can also be used to demonstrate mineral hardness, light refraction and cleavage. While each specimen will vary slightly in shape, size and color, it will measure approximately 3" in length. Each is individually packaged, labeled & barcoded for easy identification and storage.
