I suppose the thing held something which was called a "crayon" at the time
-- maybe something like a modern pencil lead, or maybe more like a piece of
chalk or whatever, I don't know.
I don't have an 18th-century English dictionary immediately available
AFAIK, but the 1828 "Noah Webster's" dictionary on-line shows for "crayon":
1. A general name for all colored stones, earths, or other minerals and
substances, used in designing or painting in pastel or paste, whether they
have been beaten and reduced to paste, or are used in their primitive
consistence. Red crayons are made of blood-stone or red chalk; black ones,
of charcoal or black lead.
2. A kind of pencil, or roll of paste, to draw lines with.
The French Academy dictionary (4th ed., 1762) on-line shows something
similar for "crayon":
<<Petit morceau de pierre de mine, ou de quelque autre matière colorée
propre à marquer, à écrire, à tracer & à dessiner.>>
