Graphite is a dark gray to black, very soft, shiny metallic mineral with a distinctive greasy feeling. One of the Earthâs softest minerals, graphite will easily leave marks on paper, which is why it is used for fine artist pencils. Even modern pencil âleadâ is composed of graphite mixed with clay.
Microcrystalline or amorphous type graphite is made up of aggregates of fine graphite crystals, which give the material a soft, black, earthy appearance. This material is usually hosted by quartzites, phyllites, metagreywackes and conglomerates.icrocrystalline or amorphous type graphite is made up of aggregates of fine graphite crystals, which give the material a soft, black, earthy appearance.
