While many aspects of the nature of amber and its organic inclusions have been reported in the literature, virtually nothing has been recorded about the inorganic - mineral, liquid, and gas -inclusions "hidden" amid the better-documented life forms. This article takes a microscopic look at the gas bubbles and crystal forms that also belong to amber's inner world. With the use of polarized light, the author also documents strain centers in the amber, including movements made millions of years ago by animals trapped in the resin.
