A practical treatise on mechanical dentistry . ogether the simplestand oii<- of the most convenient vulcanizers extant. In vulcanizing, the heat should he maintained at 3200 for aboutone hour and ten or twenty minutes. Vulcanization may be effected RUBBER OR VULCANITE BASE. 311 at a lower heat, but the time must be proportionately extended;or a higher heat being employed, a less time will be requiredto vulcanize. Care should be taken, however, not to overheat,as the rubber is thereby rendered dark and brittle, and theimportant property of elasticity impaired. The time and degreesof heat mentioned, therefore, may be regarded as the safest,and as yielding the best results, though with other rubber com-pounds, and the use of modified forms of vulcanizers, corre-sponding differences in time and temperature may be required,and which can only be accurately determined by vulcanizing test-pieces of rubber. In this connection the readers attention is called to some practi-cal observations on the subject of steam pressure in vulcanizing,.
