 The earliest evidence of the use and applications of nanotechnology can be traced back to carbon nanotubes, cementite nanowires found in the microstructure of wootz steel manufactured in ancient India from the time period of 600 BC and exported globally.Although nanoparticles are associated with modern science, they were used by artisans as far back as the ninth century in Mesopotamia for creating a glittering effect on the surface of pots.In modern times, pottery from the Middle Ages and Renaissance often retains a distinct gold- or copper-colored metallic glitter.
