Mica Powder and Polymer clay - the Perfect Pair

Eye Shadow. Eye shadows are a good alternative to Perfect Pearls or Pearl Ex Pigments and substantially cheaper. They are great to have if you want a lot of colors at a low cost, or if you use micas for faux polymer clay techniques which tend to use up a lot of powder. On the downside, eye shadows contain chalky earth pigments, as well as the micas.

Identification of Clay Minerals by X-Ray Diffraction ...

Since X-ray diffraction patterns are directly related to crystal structures. X-ray identification is, in principal, better suited to the recognition of structural groups and structural varieties than of chemical species. Well-formed kaolin, mica, and chlorite structures give rise to characteristic 7, 10 and 14Å spacings which are relatively easily identified.

Introduction to Clay Minerals & Soils

Clay minerals also have the ability to attract water molecules. Because this attraction is a surface phenomenon, it is called adsorption (which is different from absorption because the ions and water are not attracted deep inside the clay grains). Clay minerals resemble the micas in chemical composition, except they are very fine grained ...
