How the Mesoamericans perfected rubber manufacturing

Published on May 28th, 2010 | by Admin


Apparently the Mesoamericans perfected the process of rubber production to the point that they could vary the quality for different uses.

New research from MIT indicates that not only did these pre-Columbian peoples know how to process the sap of the local rubber trees along with juice from a vine to make rubber, but they had perfected a system of chemical processing that could fine-tune the properties of the rubber depending on its intended use. For the soles of their sandals, they made a strong, wear-resistant version. For the rubber balls used in the games that were a central part of their religious ceremonies, they processed it for maximum bounciness. And for rubber bands and adhesives used for ornamental wear and for attaching blades to shafts, they produced rubber optimized for resilience and strength.

All of these, according to the research by Professor Dorothy Hosler and Technical Instructor Michael Tarkanian of MIT’s Department of Materials Science and Engineering, were most likely achieved by varying the proportions of the two basic ingredients, latex from rubber trees and juice from morning-glory vines, which were cooked together. A paper describing the findings will be published soon in the journal Latin American Antiquity.

The research builds on a paper that Hosler, Tarkanian and Sandra Burkett, then an assistant professor at MIT, published in Science in 1999 that showed for the first time that the Mesoamerican people could have used the combination of two ingredients to produce rubber. The new work, which draws on a combination of laboratory experiments, recovered artifacts and the descriptions left by early explorers, demonstrates how varying the formula could fine-tune the rubber’s properties.
