Tree sap is often thought to be transformed to amber, but amber is polymerized resin, which is an entirely different substance. Resin is semi- solid, whereas sap is liquid. Resin is exuded by a tree in response to injury or disease. Because resin must be polymerized to become amber the process takes tens of millions of years in nature. Polymerization is the process whereby small molecules combine to become large ones. In modern manufacturing, catalysts are used to speed up natural polymerization reactions. Processes that would naturally take years can be done in minutes if the proper catalysts can be found. Catalysts are chemicals that participate in a transformative chemical process but are not themselves transformed. Unfortunately, no process for rapidly converting resin to amber using catalysts has yet been discovered.
