Ancient Chinese Inventions

    AD 105  is often known as the year in which papermaking was invented. In that year, historical records show that the invention of paper was reported to the Chinese Emperor by Ts'ai Lun, an official of the Imperial Court. Recent archaeological investigations, however, place the invention of papermaking some 200 years earlier. Ancient paper pieces from the Xuanquanzhi ruins of Dunhuang in China's northwest Gansu province apparently were made during the period of Emperor Wu who reigned between 140 BC and 86 BC. 

 

   Early Chinese paper appears to have been made by from a suspension of hemp waste in water, washed, soaked, and beaten to a pulp with a wooden mallet. A paper mold, probably a sieve of coarsely woven cloth stretched in a four-sided bamboo frame, was used to dip up the fiber slurry from the vat and hold it for drying. Tree bark, bamboo, and other plant fibers were used in addition to hemp during paper production process.
