- Plumbago (disambiguation)
Plumbago is derived from the
Latinword Plumbum meaning lead. It may refer to:
Plumbago", the leadworts, a genus of flowering plants
Plumbago (butterfly)", a genus of skipper butterflies
*Used generically for lead ores such as
galenaand lead oxides such as Red lead.
*An old name for the mineral
graphite, from its ability to make a smooth black mark on paper like lead.
*Finely powdered graphite used in the commercial metal foundry industry, as a parting dust in high temperature foundry work. It is a slick powder that prevents sand from sticking to patterns, and to keep sand from sticking to itself. It is also used as a release agent for coating steel core pins when used in aluminum castings. Thomas Edison used the word plumbago to mean graphite. This misleading usage may have arisen from a confusion of powered graphite for powdered lead.
