Paper manufacture:

Paper was not used in India until the eleventh century. This Chinese invention of the first .century A.D. reached India mainly through the Ghorian conquerors. Once introduced. its  manufacture spread quickly, and by  the middle of  the fourteenth century, paper became so cheap that it was used not only for writing but also for wrapping purposes by  the sweetmeat sellers. Mation The know-how of liquor distillation also came to India during the thirteenth century. Though it has been argued by  the famous Indian chemist P.C. Ray (1861-1944 A.D.)  and recently by the Allchins and Needham on the basis of archaeological evidence, that :iquor distillation Was known in ancient India, the stills seem to have been small and inefficient. With the thirteenth century came various types of stills (for liquor as well as  for rose-water) and therc is little doubt that the manufacture of  distilled spirits received great impetus.
