1. The petroleum processing plant will transport the powder or liquid synthetic rubber to the Eraser from China manufacturing plant. If natural rubber was to be used, it was shipped in solid chunks that workers had to crush and dissolve.
2. Mix the rubber with ground pumice (to make the rubber slightly harder), iron oxide (to make the rubber pink), vegetable oil, sulfur, and other substances.
3. Heat the mixture so that the sulfur mixes with the rubber to increase the strength of the rubber and make it more durable.
4. Feed the soft, still warm material into a punch (extrude into a die) to make long, thin rubber sticks. Cut the rubber stick into small pieces with a knife, wait for it to cool, and then transport it to the pencil factory to make Eraser on pencils.
5. The block eraser used alone is made by injecting the heated rubber mixture into various shapes of molds. After cooling, open the mold and Eraser from China in various shapes will come out.
