    Insoluble in water.


    Other characteristics

    Weakly thermoluminescent. Small clear


    fragments become nearly invisible when


    placed in water, since its refractive index is


    close to that of water. May fluoresce intense


    yellow under SWUV, with yellow


    phosphorescence, and pale yellow


    phosphorescence under LWUV. Not


    radioactive.
