Mica. Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica is heat resistant and does not conduct electricity.
Talc comes from rock deposits found all over the planet and is mined like many other valuable minerals, but only the highest grade talc, meeting our purity specifications, is used for talcum powder.
