The creation of actual paper is fixed some three millennia later, around A. His recipes remained closely guarded secrets for at least a few hundred years, but the ingredients likely included cotton rags as well as mulberry and hemp. Because Arab regions lacked good supplies of wood or other fibrous plants, their cultures developed paper made almost entirely from textile scraps.
That innovation qualifies Ts’ai-Lun’s material as the first modern paper. Although these papermakers did not beat the cloth very finely by today’s standards, they achieved a smooth writing surface by coating both sides with starch paste.
Less than a year after Charles Herty opened his research lab, a Georgia weekly called the Soperton News printed its March 31, 1933, edition on experimental paper made from southern pine trees.
Seven months later, nine other newspapers followed suit.
Herty had championed, cajoled, and shepherded a watershed event in the centuries-old history of papermaking.
Visionary and entrepreneur, twice president of the American Chemical Society, he expounded an idea which was revolutionary in that time: Southern pines could be grown as crops and made into excellent white paper.Herty had saved these forests in 1903 by inventing a new method of extracting resin, used to make turpentine, that did not scar and damage the trees.Now, he turned to chemistry to address another concern: the high level of resin in the pines’ wood, which was believed to block the bleaching with acidic sulfite solutions needed to make white paper.The papermakers’ demand for cotton rags outpaced the supply by the early 1700s.That was when RÉnÉ de RÉaumur, a French chemist and naturalist, is said to have reasoned that if wasps could make paper from wood, so could people.During a lecture in Germany 30 years earlier, Herty had heard that the sulfite process could be applied to the Tannenbaum the Germans used as Christmas trees.Herty reasoned that, like these trees, younger pines in the southern United States would be less gummy than mature ones.The region’s abundant pines would provide an economic boost."In order to give our people a living and get them out of one-room shacks, it may be desirable in the next 15 years to eat into our forest capital," he told the Savannah Morning News.Herty built his research facility and pilot plant with funds provided by a Savannah businessman, the state of Georgia, and the Chemical Foundation, a nonprofit organization established after World War I.He directed his new lab to make pine into the pulp that would become paper, using acidic sulfite solutions to digest the wood, remove impurities and increase the effectiveness of bleaching agents.
