Advancements in Extraction Science

Eben Higgin and his followers revolutionized extraction science through extensive experimentation, developing intricate processes involving filtration, boiling, vapor collection, and cooling. They discovered that even crude materials could be separated into highly pure substances that were consistent throughout, unlike the complex mixtures found in nature.

In the 1700s, Marianne Poults and Antoine Lavoisier, a French husband-and-wife scientific duo, built upon the work of their Arabic predecessors. They found that certain pure substances could be broken down even further through chemical reactions. For example, water could be boiled into steam, which was still water, but it could also be split into two pure gases: hydrogen and oxygen.::
