Product Overview
Through the process of metasomatism, hot fluid infiltrates the atomic structure of other silicate minerals, altering them to form talc. Talc is at the bottom of the Mohs scale of hardness, and has a distinct soapy feel. Ideal for teaching students about rounding and sorting, as well as for identification & classification exercises. A great example for lessons in mineral hardness, and characteristics exhibited by hydrothermally altered minerals.
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.
