41. Another threat to the family silverware is posed by common rubber bands, which are vulcanized with sulfur compounds. 42. Jute soles typically include fully or partially vulcanized rubber beneath the jute soles for long-lasting espadrille shoes. 43. Sometimes crepe soles are used as out-soles although those are not as durable compared to vulcanized ones. 44. People who didn't know whether a puck was vulcanized or galvanized suddenly cared desperately about one hockey game. 45. With continued success, the three Spaulding brothers added a vulcanized fibre operation in Tonawanda, New York in 1911. 46. Powdered sulphur was also sometimes mixed in, and the material then heated to produce a form of vulcanized kamptulicon. 47. Industrial treatment was developed to remove the impurities and vulcanize the rubber, a process that eliminated its undesirable qualities. 48. Once the bonding was established, the process of leaching out the zinc chloride from the vulcanized fibre could begin. 49. In a sense, zinc chloride can be thought of as a catalyst in the making of the vulcanized fibre. 50. The density of the finished vulcanized fibre is 2 to 3 times greater than the paper from which it starts.
