Graphite material for pencil making
Pencil lead is most commonly a mix of powdered graphite and clay. It is chemically unrelated to the metal lead, whose ores had a similar appearance, hence the continuation of the name. Plumbago is another older term for natural graphite used for drawing, typically as a lump of the mineral without a wood casing.
