Micas come in different particle sizes. The ones that are smaller than 20 microns give a satiny appearance while large micas with up to 150 microns provide a sparkle effect.
Untreated micas are transparent and are thus coated with iron oxide pigments (black, red, yellow) and titanium dioxide to create silver-white but also gold, copper and bronze shades. Others are coated with an additional layer of colored pigment including carmine, ferric ferrocyanide, D&C reds, chromium oxide and aluminum oxide. This combination results in a brilliant color effect.
