There are many different forms of mica, and they may be found all over the world; nonetheless, the beauty industry has long preferred Indian mica due to its high quality. Mica flakes (called abrak in Urdu and written as ابرک) are also used in Pakistan to embellish women’s summer clothes, especially dupattas (long light-weight scarves, often colorful and matching the dress). Thin mica flakes are added to a hot starch water solution, and the dupatta is dipped in this water mixture for 3–5 minutes. Another use of mica is as a substrate in the production of ultraflat, thin-film surfaces, e.g. gold surfaces. Although the deposited film surface is still rough due to deposition kinetics, the back side of the film at the mica-film interface is ultraflat once the film is removed from the substrate. Freshly-cleaved mica surfaces have been used as clean imaging substrates in atomic force microscopy, enabling for example the imaging of bismuth films, plasma glycoproteins, membrane bilayers, and DNA molecules.
