 * History of Plastics

"In the age of discovery, the attempt to find a spice and novel trade route to West Indies eventually led Cristopher Columbus to discover unknown continent; now it is the United States of America. In some sense, it is true that great achievements were sometimes followed by unexpected lucks or divine will.""The first discovery of synthetic plastic was not different from other Great achievements. It was created with an attempt to replace the ivory, which was a material to make the billiard ball, but it was priceless and rare at the time. Although it is controversial arguing ivory was out of stock, it is true that Phelan and Collender, the largest manufacturer of billiard balls in the 1880s, proposed that a creator who can replace the ivory with a synthetic material will take 10,000$ as a contributor. In an attempt to discover new synthetic substitute, at the same time, John Wesley Hyatt used Nitrocellulose to substitute ivory.""Nitrocellulose was invented by Christian Friedrich Schönbein around 1846 in the University of Basel at Switzerland. In 1862, Alexander Parkes experimented on this material because it was flammable and high elasticity which were not good for using a daily basis. Adding Alcohol and Ether, he ameliorated its drawbacks so that it losed a hardness and mold-able properties which was named Parkesine, but it also had a critical blemish in that it was shrinkable when dehydrated.""Knowing that Parkes innovated Nitrocellulose's mechanical properties, John Wesley Hyatt struggled to upgrade its hardness, thinking that it would be more appropriate for replacing ivory for billiard balls. One day, when he putted a Camphor tincture into Nitrocellulose, it started to dissolve. Camphor tincture is dermatological medicine, mixing camphor with Alcohol, which was rooted from camphor tree. In 1869, this new material John called it as Celluloid was mold-able under a certain heat range and, when quenched, its hardness and elasticity can be comparable with a material derived from Ivory. It was, however, too brittle to be a substitute for the billiard ball. Instead of using it as a replacement of ivory, other basic indispensable supplies consist of Celluloid. Not only was it a milestone for thriving the plastic industry, but it was also the fortune acquired from the effort to find a replacement of ivory. This"

feedback from Chen--

In my viewpoint, the introduction is a little bit long and the first paragraph is more like a story. You can also add some link and reference in the introduction. Category:Plastics Category:Recycling __NOINDEX__ __NEWSECTIONLINK

chandru;The topic is good And the structure of the article is good
