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.
