MUSCOVITE MICA BOOK
Muscovite Mica Book Specimen. Featuring many slim sheets of Mica together forming a book. This lovely silvery Mineral possesses special properties like electrical, thermal and electromagnetic insulation and shielding. We have personally measured these properties with a Trifield meter for shielding and Mica is one of the best natural radiation shields. It has been used scientifically for these purposes for well over a hundred years. This specimen is mounted on a perspex pad for enhanced display and to make some handling possible. Mica can be flaky and comes apart in thin sheets much like flexible plastic. It is a popular and unusual mineral that appeals to people of all ages. Muscovite is just one variety of Mica, named for the Russian province of Muscovy, known for its sheet mica.
