    Early historyUseVarietiesFormationEtymologyQuotesPropertiesGeologySafetyQuartz was the mineral upon which the Stone Ages were based. With few exceptions, most early stone tools were fashioned of quartz. Outcrops of quartz that were suitable for tool manufacturing were targeted by some of the earliest known mining activities and the mined quartz was traded across vast distances, even before humans began to establish agricultural societies.See more on esci.umn.edu
  • University of Minnesota’s Mineral Pages: Galena

    Galena is the most abundant lead mineral, has been mined for millennia, and remains our major source of that metal. It is a metallic, lead-gray mineral with cubic cleavage and a distinctly high density that makes galena samples feel much ‘heavier’ than expected for their size. Because it melts at a relatively low temperature and is so
