Pre-chemistry — graphite before laboratories

Evidence: Well-supported at the level of mining and craft history; specific ancient identifications of “graphite vs molybdenite vs galena” are often later reconstructions.

What this page is

Before there is a chemist named Brodie, there is a slippery black solid people write with and grease with. They do not have the word graphene. They often do not even have a clean distinction between graphite and look-alike minerals.

This is the floor of the timeline. Monday posts can start here when the hook is “graphene is new; carbon sheets are not.”

Craft and names

Europe called the stuff plumbago or black lead — lead-like mark, not elemental lead. That confusion lasts in the word pencil lead.
Graphite as a mineral name is 18th-century scientific German/Latin usage (often tied to A. G. Werner, late 1700s): graphein, to write. The name is about marking paper, not about 2D physics.
Swedish and German chemists in the late 18th century (Scheele and others in that conversation) work out that this mineral burns to carbon dioxide / behaves as carbon, separating it from molybdenite and other metallic-looking blacks. Treat textbook dates as consensus history, not as a lab notebook you hold.

Mines and pencils

The Borrowdale deposit in Cumbria (Seathwaite) is the famous early-modern European source of unusually pure solid graphite, exploited from the 16th century and tightly controlled. It feeds pencil-making and later strategic uses (moulds, lubrication).
Conté in France (1790s, Revolutionary shortage of English graphite) mixes graphite powder with clay and fires rods — the ancestor of graded pencil “leads.” That is powdered graphite, not a monolayer device.
Graphite is already an industrial mineral: foundry facings, crucibles, lubrication, later electrodes and (in the 20th century) nuclear moderators. None of that requires knowing a Dirac cone.

What you cannot claim

That Neolithic marks or a specific Egyptian cosmetic are graphene. Carbon blacks and soots are not automatically honeycomb monolayers.
That anyone “used graphene oxide in antiquity.” GO is a 19th-century chemical product ([[timeline/before-1900]]).
That pencil lead is a graphene product in the 2004 sense. It is polycrystalline graphite plus clay.
