Mica sheet with a nice yellow-gold color.
Mica is characterized by its easy exfoliation in thin flexible, elastic and very shiny sheets. They are generally found in igneous rocks such as granite and metamorphic rocks such as schist. The most abundant varieties are biotite and muscovite.
Thanks to their characteristics of elasticity, flexibility and resistance to heat and water, they make them a precious material for industry due to their properties as electrical and thermal insulators. It is used as insulation for high voltage and high power machines, turbo generators, electric motors, and some capacitors.
The mineral includes a label with the name and origin and is attached to a cardboard box. 4 cm square.
*The price is per unit (a single cardboard box of the four shown in the photo)
Since the minerals are natural, you will receive a piece similar to the one in the photograph. The minerals come in cardboard boxes and are glued to a porex base with hot silicone; these can be removed using ethyl alcohol without damaging the mineral. The size is approximate.
