About Eisco Biotite Mica Specimen
Biotite mica is a mineral that forms from cooling magma. It forms in thin sheets that are individually weak, but comprehensively strong. Useful when teaching lessons about physical properties of minerals, as well as Bowen's reaction series. A couple samples can also act as polarizers.
