Transcript of Muscovite Mica

Origin of the Name Muscovite Mica:
→ The meaning of this stones name relates to one of the places where it was used in large quantities as a building material. In the Muscovy region of Russia it was used to make a window material, known as Muscovy glass.
→ It is a quite common stone and has been found in a large number of locations including Russia, Austria, Switzerland, the Czech Republic, New Mexico, Brazil and the USA. Also in the Blue Ridge and Piedmont provinces.
→ There are two types of Mica’s: black mica and white mica; muscovite is a white and biotite is a black mica.
→ Founded by James Dwight Dana in 1850.
→ Mica has been actively mined in North Carolina since the mid-1800’s. Muscovite Mica Nyashia Ferguson
Perl Singh Color → This stone may be colorless to a mixture of colors.
→ This mineral is specifically colorless, white, beige, yellow, brown, gray, green, pink, purple, red, black; occasionally multicolored. Chemical Properties This mineral belongs to the Silicates group.

This Chemical is composed of:
→ Potassium
→ Aluminum
→ Silicon
→ Hydrogen
→ Oxygen
→ Fluorine KAI Si O (OH) 3 3 10 2 Crystal Shape → Pseudo-Hexagonal
A Pseudo-Hexagonal is a hexagon without a genuine shape. Hardness 2-2.5
→ This hardness number determines that the mineral can be scratched by a fingernail and a copper penny. The copper penny and the fingernail can determine the hardness of this because Mohs Hardness Scale goes from Talc to Diamond. Since a Diamond is very hard to scratch it goes on the bottom, a diamond can’t be scratched by any other mineral but itself. The Muscovite Mica can be easily scratched by a fingernail and a copper penny. Distinguishing Characteristics → It can be used for painting. It makes the painting very shiny and elegant.
→ Muscovite Mica’s characteristics consist of the thin Plate-like particles. It has a hydrophilic nature, a high thermal stability. The particles are rough but are made of elastic materials. This mineral is very bright and is often used to make the paint on walls or ceilings shiny. Value Muscovite is a very common form of Mica that there is. It is very abundant, although it is abundant Muscovite is found with other minerals also known as accessory minerals.
Uses of Muscovite Mica Muscovite Mica can be found in igneous and metamorphic rocks. The name Muscovite comes from Muscovy-Glass a name used for the mineral because of its use in Russia for windows. Nowadays it is used to put a reflector in paint. It gives the paint a glossy feature. Muscovite is has very high heat resistance so it helps insulate the house. Muscovite is mainly used in paint and roofing but it can be found in some jewelry that uses this mineral as a product. Historically it was used for the window glass. Muscovite was also for circuit boards in the past. Muscovite is usually combined with other minerals to make a final product.
Where can Muscovite Mica be found? North Carolina, India, Pakistan, New Mexico, New England, Connecticut, Spruce Pine Mining District. Myths / Superstitions
of Muscovite Mica Legend is that this mining of mica led Hernando DeSoto to the Spruce Pine area around 1540 in search of mineral wealth that he thought to be gold and silver. He found only silver mica better known as muscovite mica.
Later, around 1744, legend is that Cherokee Indians mined semi-weathered feldspar and kaolin from the Spruce Pine pegmatites and used oxen-drawn sleds to transport it to the coast where it was loaded on ships bound for England. In England, it was used as an ingredient for patented English ceramic wares.
From 1767 to 1911, mining of feldspar and mica occurred sporadically. Mica was mined to fuel the demand for the newly-developed Edison electric motor in 1878. The motor required the electrical insulating properties of sheet mica. Bibliography
