	MUSCOVITE (Potassium Aluminum Silicate Hydroxide Fluoride)
		Muscovite is a common rock forming mineral and is found in igneous, metamorphic and detrital sedimentary rocks.
		Muscovite has a layered structure of aluminum silicate sheets weakly bonded together by layers of potassium ions.
		Muscovite is not often valuable as a mineral specimen but is often associated with other minerals of extrodinary beauty and value.

		The plane of the optic axes is perpendicular to the plane of symmetry and the acute bisectrix nearly normal to the cleavage; the optic axial angle is 60-70°, and double refraction is strong and negative in sign.
		Muscovite frequently occurs as fine scaly to almost compact aggregates, especially when, as is often the case, it has resulted by the alteration of some other mineral, such as felspar, topaz, cyanite, andc.; several varieties depending on differences in structure have been distinguished.
		Muscovite is of wide distribution and is the commonest of the micas.

		Muscovite, also known as potash mica, is a phyllosilicate mineral of aluminium and potassium with formula: KAl2(AlSi3O10)(F,OH)2.
		Muscovite is the most common mica, found in granites, pegmatites, gneisses and schists, and as a contact metamorphic rock or as a secondary mineral resulting from the alteration of topaz, feldspar, kyanite, etc. In pegmatites, it is often found in immense sheets that are commercially valuable.

		Without neglecting the standard textual documents used by historians to construct an understanding of Muscovite society, she uses to great and convincing effect the knowledge encoded in paintings and other forms of pictorial representation in order to shed light on the place of royal women in the historical development of the Muscovite political landscape.
		Taking exception to the standard historical view according to which the rise of the Muscovite state saw the royal women slowly disappear into the private realm of family life and the terem, Thyret demonstrates that the wives of grand princes and tsars continued to serve the interests of the state in important ways.
		While bolstering the political and religious position of the Muscovite royal dynasty, the myth also saved some royal women from an immediate loss of prestige in the event of infertility., In a thoughtful treatment of Solomoniia Saburova, wife to Vasilii Ill, Thyret shows how she transcended biological motherhood in the literary imagination of the day.
