Product Overview

Found within igneous and metamorphic rocks. Biotite mica's sheet like appearance and glassy luster make this mineral easy to identify. Formed from cooling magma, biotite's layers are individually weak, but comprehensively strong. Excellent for classroom mineral study and identification. Mica's thin and layered structure is perfect for demonstrating variable hardness and cleavage, physical properties of minerals, as well as Bowen's reaction series.
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.
