In 1 8 3 9 rubber wasn't much use* It melted and oozed in hot weather. In cold it stiffened and cracked. T o remedy these failings, Charles Goodyear worked ardently but unsuccessfully. Yet he kept on. And the final solution of the problem came by accident when onto a hot stove Goodyear spilled a mixture of latex and Sulphur. This was the birth of vulcanization. In the years since then, Sulphur has contributed further t o rubber's versatility. By varying the proportion of Sulphur in the vulcanization mix, the properties of the rubber are changed — ranging from the battery case's rigidity to the rubber band's flexibility. And when supplies of natural rubber were cut off by war, Sulphur in various forms was found to be a most important element also in the production of synthetic rubbers. oldest United States producer of crude sulphur, has been supplying this essential raw material for over 33 years.
