Mica Information


Mica is a natural mineral mined from the earth to create dramatic lighting and lamp shades.

Mica was not always the expensive material that it is now. In the early American colonial years, muscovite mica was sometimes found in such large sheets that it could be used as window material for houses. Prices were competitive with glass which had to be imported from England. A very large piece of about 1 meter high can be seen in the Smithsonian Museum in Washington.

Muscovite, commonly known as white mica, is a member of the mica family of minerals. The mica minerals all share the property of perfect basal cleavage, which means that layers of mica can be peeled off of a mica crystal in very thin sheets. It is especially easy to peel off large numbers of paper-thin sheets from a muscovite crystal. Consequently, crystals of mica are often referred to as books of mica.

The famous artisan Dirk Van Erp incorporated mica in many of his lighting creations. He was the most important metalsmith and coppersmith of the Arts and Crafts movement. Lamp Shade Pro offers numerous styles of exclusive mica lamps, mica pendant lights and mica lamp shades, many are USA made.

"Thin transparent sheets of mica were called "isinglass" and used for peepholes in boilers, lanterns, stoves, and kerosene heaters because they were less likely to shatter compared to glass when exposed to extreme temperature gradients. Such peepholes were also used in isinglass curtains in horse-drawn carriages and early 20th century cars. A book about a journey in a Model T Ford car describes isinglass curtains as follows: "Oiled canvas side curtains were put up over the windows for wind, rain, and cold (there were no heaters) and were held in place with rods that fit into the doors and twisting button snaps around the perimeter... 'Isinglass' peepholes in the curtains allowed limited visibility. Isinglass was made of thin sheets of cracked mica." - Wikipedia
