History :

The first written accounts of the attributs of shungite (then termed 'slate rock') date from the 16th century regin of Ivan the Terrible (the Grand Prince of Moscow) and document particularly pure spring water that sprang from it. During the reign of Peter the Great (1682-1725) a number of spas were establish that were deemed particularly beneficial to those with liver problems and local copper miners suffering from heavy metal posioning. Peter ordered by decree that all his soldiers must carry a piece of shungite with them, to put it in their flasks to ensure pure disinfected water. In the 1970s, the ability of shungite to be resistant in a chemically aggressive environment, coupled with its high electrical and low thermal conductivity, was explored. Further studies over the last 40 years have confirmed that the unusual physicochemical and structural properties of shungite give it numerous industrial and environmental applications, including the ability to remove pathogenic baceria and heavy metals from contaminated water. Other valuable properties of shungite include its absorptional, catalytic, reduction-oxidation properties, as well as its ability to screen off electromagnetic and radio radiations, making it useful in various branches of science, industry and technology.
