WhiteRaven,
I found this site that sells several types of
Mica, I still am not quite sure of what it is but it certianly seems to be expensive. I had never heard of it before.. but seeing it in this form it does look familiar to me.
I also found this on Mica:
"Mica is a naturally occurring mineral, which is present in most granite rock formations. It occurs as a geological fault between two layers of hard rock. In brief, Mica is a generic term applied to a group of complex alumino-silicate materials, having a plate like structure, with different chemical compositions and physical properties. Unfortunately, most of the world’s mica is commercially of little value and is only suitable for grinding into mica powder. Deposits of mica suitable for use in electrical applications are found in India, Madagascar and to a lesser extent in Canada, where the mineral is mined and processed (cut and split).
TYPES OF MICA
Muscovite mica is the most commonly used mica in electrical insulation. Muscovite mica is by far the best electrical properties of all the micas and is commonly available in two colour groups:
Ruby (varies in colour from clear through pink to red / brown)
Green (varies in colour from pale green through olive to a dark green)
The crystal structure of the two types is very similar though the most commonly used of the two is ruby mica. Ruby mica is harder than green mica and can be split into very thin films.
Phlogopite mica is commonly called amber mica and varies in colour from light silver to dark brown. Phlogopite is softer than muscovite micas and has poorer electrical properties and chemical resistance. The material can however withstand considerably higher temperatures without dehydration and has good abrasion characteristics. It is commonly used in the manufacture of heating elements and as the base material for the manufacture of commutator micanite."
Yawn right?
But more interestingly to us I think was this:
Ancient legend and folklore claim: Walking on Mica in bare feet is therapeutic to conditions such as arthritis and stiff joints, even curing headaches.
Looks like you got a nice little bonus with your win!
