Webster's Revised Unabridged Dictionary
    • n Graphite (Min) Native carbon in hexagonal crystals, also foliated or granular massive, of black color and metallic luster, and so soft as to leave a trace on paper. It is used for pencils (improperly called lead pencils), for crucibles, and as a lubricator, etc. Often called plumbago or black lead.

Century Dictionary and Cyclopedia
    • n graphite One of the forms under which carbon occurs in nature (see carbon), also known as plumbago and black-lead. It has an iron-gray color and metallic luster, and occurs in foliated masses and embedded scales. It is soft and unctuous to the touch, makes a black shining streak on paper, and is used chiefly in the manufacture of pencils, crucibles, and portable furnaces, for burnishing iron to protect it from rust, and for counteracting friction between the rubbing surfaces of wood or metal in machinery. It is a conductor of electricity, and in the form of a powder is used for coating the non-conducting surfaces of molds in making electrotypes. The most important regions supplying graphite are the Alibert mine in Siberia, which furnishes the best material for lead-pencils, and Ceylon, whence comes a large part of the coarser material used for stove-polish and for lubrication. There are also extensive mines of graphite near Lake Champlain.
    • n graphite Same as graffito. See the extract.
