Types of Mica

BLOCK MICA - USArtQuest MicaTiles™

Muscovite is often called white or Indian mica, and is the most common mica mineral. The world’s chief deposits are found in India.

Being flexible, elastic and tough, as well as having high tensile strength mica can withstand substantial mechanical pressure perpendicular to the plane. The lamination has cleavage so that it can be easily split into thin, chemically resistant and elastic sheets that are fireproof, infusible, incombustible and non-flammable. While mica is flexible, elastic and tough, it is relatively soft. Mica has practically zero moisture absorption.

Block Mica is sometimes called book-form. This is a muscovite that looks much like a book because of the uniform sizes of all the mica pieces. To obtain such form of splitting, mica block is split into various thin layers of less than 1mil. When reassembled, the pieces resemble the pages of a book.

Heat Resistant Natural Mica

Where applications call for very high temperatures, Amber Phlogopite has a more reflectiveappearance and is able to withstand temperatures up to and beyond 1200°F.

Mica Flake ∙ Mica Glitter ∙ Powdered Mica

The principal use of ground mica is in gypsum wallboard joint compound, which acts as a filler/extender. The mica provides a smoother consistency, workability and prevents cracking. In the paint industry, ground mica is used as a pigment extender that also facilitates suspension due to its light weight and platy morphology.

Flake mica (which includes flake & glitter) comes from several sources: the metamorphic rock called schist. Sheet mica is considerably less abundant than flake and scrap mica, and is occasionally recovered from mining scrap and flake mica.

While we strongly encourage experimentation for your application, most of the flakes and mica glitter burn out at around 400 – 500 degrees.
