An Inventin That Changed the Wrld
Can yu imagine a wrld withut bks, newspapers, r magazines? All f these things depend n ne inventin—papermaking. It, mre than any ther inventin, was respnsible fr the rapid spread f infrmatin that shaped ur mdern wrld.
In ancient China, many different materials were used t write n, such as animal bnes, brnze ware, stnes, wd, bamb, and even silk. In the Western Han Dynasty, there was als a very early frm f paper made frm jute—a fibre that cmes frm plants. Hwever, all f these materials were either difficult t use and stre, r very expensive.
As the head fficer f the palace wrkshp fr the emperr in the Eastern Han Dynasty, Cai Lun became interested in trying t slve the prblem. Different methds fr creating smething t write n were tried, but nne were ideal. In his time, sme kinds f bark—the uter part f trees—were used t make clthes. Frm past experiences, Cai Lun gt the idea that bark, certain plants, and ld clthes culd be used t make a special material suitable t write n.
In the first step f Cai Lun’s experiment, all the ingredients were mixed and biled in water. Then, this material was beaten, cut up, and mixed with water again. Next, the liquid was pured ver a bamb screen, leaving just the fibre. Finally, this fibre was dried and pressed t frm paper. T everyne’s surprise, this paper was sft, light, easy t make and use, and mst imprtantly, cheap. In 105 CE, Cai Lun shwed his creatin t the emperr. The emperr was very pleased and praised Cai Lun fr his great wrk.
Later n, the papermaking technique nt nly speeded up the develpment f Chinese culture, but als changed civilizatins arund the wrld. It first spread t China’s neighburing cuntries and finally reached Eurpe thrugh Arabic cuntries in the 12th century. When the use f paper and printing came tgether in later centuries, it led t a rapid increase in the number f bks. This resulted in a new birth f knwledge, creating the wrld we have tday.
