Ancient Rubber-Making Masters

3000 years before we started using rubber, Ancient civilizations in Mexico and Central America were making it. This included the Aztec, Olmec and Maya civilizations. They used a natural latex found in some plants.

Ancient rubber makers harvested latex from rubber trees and mixed it with juice from morning glory vines, which contains a chemical that makes the solidified latex less brittle.

The Mesoamerican-rubber paper will appear in an upcoming issue of the journal Latin American Antiquity.
