How long should I heat the rubber to vulcanize it?

Vulcanization is the combination of Latex with Sulfur in the presence of heat. If a rubber is not vulcanized, it has poor keeping qualities and usually does not keep its original form, especially upon stretching. We recommend 24 hours at 100-120 degrees Fahrenheit or 38-49 degrees Celsius. Or, let it stay at room temperature for about 4 days.
