Product Overview

The massive, gray variety of limestone is often found deposited in marine environments. It is made up of organic material, primarily calcium carbonate. Excellent for demonstrating the tendency of calcium carbonate to effervesce in acid, and is perfect for identification and classification exercises.
While each specimen will vary slightly in shape, size and color, it will measure approximately 1" in length. Pack of 12. Each set is individually packaged, labeled & barcoded for easy identification and storage.
