#MinCup24 Quartz vs Mercury..

Mercury may be a toxic horror, but it is perfectly natural, and also perfectly, wonderfully weird: a liquid metal of very high density.

In the Hunterian museum collections at University of Glasgow. #Geology #Mineralogy #Mercury #Eeeek https://www.gla.ac.uk/collections/#/details?irn=17491&catType=C&referrer=/results&q=mercury+ferguson
