Goodyear

In 1837, Charles Goodyear obtained his first rubber-processing patent (U.S. No. 240). At this time, the original india-rubber would become sticky melt in the summer heat. Goodyear resolved to solve this problem. After various unsuccessful methods, he devised a process to treat the India rubber with metallic solutions such as copper nitrate and strong acid for a few minutes, followed by washing with water. Such process treated both rubber on the surface and below the surface to a useful condition. His patent explained this method, and also the use of a water paste of quicklime to bleach the rubber for which he listed various new purposes. He obtained additional patents as he continued to revised his process by using sulphur and oil of turpentine.
