12PK Raw Biotite Mineral Specimen, 1" - Geologist Selected Samples - Eisco Labs

• BIOTITE MICA | Found within igneous and metamorphic rocks. Biotite mica's sheet like appearance and glassy luster make this mineral easy to identify
• GREAT FOR GEOLOGY CLASSROOMS | 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
• GEOLOGIST SELECTED | Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features
• LOCALLY PROCESSED | Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY
• INDIVIDUALLY PACKAGED & LABELED | Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification

Raw Biotite Specimen
Set of 12 Samples, 1"

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.

Selected & Processed by a Geologist.
Each and every specimen is selected and hand processed by an actual geologist, ensuring that each sample exhibits defining features. Rocks and minerals are sourced from a variety of locations around the world and are processed by hand in Victor, NY.
