- Found within igneous and metamorphic rocks. Biotite mica's sheet like appearance and glassy luster make this mineral easy to identify
- 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. This set of twelve samples is excellent for group study and examination
- Each specimen is selected and hand processed, ensuring each sample exhibits defining features
- Sourced from a variety of locations around the world
- Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification
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. Each is individually packaged, labeled & barcoded for easy identification and storage.
