The word graphite derives from the Greek word 'grephein', which means to write or draw. Graphite's uses extend beyond creative paints and pencils to batteries, crucibles, refractory bricks, car brakes and for electrotypes. It's a metamorphic mineral, with approximately one million tonnes sold annually in the form of tiny graphite ...
Graphite is a dark gray to black, very soft, shiny metallic mineral with a distinctive greasy feeling. One of the Earth's softest minerals, graphite will easily leave marks on paper, which is why it is used for fine artist pencils. Even modern pencil 'lead' is composed of graphite mixed with clay. Paradoxically, even though graphite is ...
