Mica or "vermiculite" is a mineral formed out of a chemical reaction between quartz and granite.  Exposed to extreme heat, the mineral expands into worm-like pieces 2000 or even 3000% of their original size, in a spectrum of brilliant colours.  The characteristics of this mineral have been known in Japan for 6 centuries.  Mica is also known as "strange stone", "breathing stone" or "miracle stone".  After the mica has been heat-expanded, it is crushed into small pieces and stuck on a non-woven backing.  Finally, the surface is coloured.
