What does colophony mean?
Colophony is the technical name for rosin, the hard, glassy, amber-colored residue that remains when the volatile oil of turpentine has been distilled out of the oleoresin of pine trees. Brittle at room temperature yet tacky when warmed, it has long been valued for its friction-giving and adhesive properties: violinists and cellists rub cakes of it onto their bows to make the strings speak, while industry uses it in soldering flux, varnishes, printing inks, paper sizing, and adhesives. The name derives from Colophon, an ancient Ionian city celebrated for its high-quality pine resin, which also gave its name to the printer's colophon. Though largely displaced in casual speech by its synonym 'rosin', colophony remains the standard term in scientific and trade literature, and contact with its dust can provoke allergic reactions in sensitive workers.
nounRosin — the hard, brittle amber-colored resin obtained as a residue from distilling turpentine from pine oleoresin, used by violinists on bows and in soldering flux, varnishes, and paper sizing.
- The hard translucent resin left after turpentine is distilled from pine oleoresin; rosin.
"The cellist drew the bow across the strings after rubbing it with a cake of colophony."
"The luthier dissolved the colophony in spirits of turpentine to make a golden varnish."
"Soldering wire is often cored with colophony flux to clean the joint as it melts."
The plural is rare, since colophony is normally treated as a mass noun referring to a substance.
"Different grades of colophonies are blended for varnish making."
Violinists owe their grip to colophony: without this sticky pine residue, bow hairs would simply slide silently across the strings.

Etymology of colophony
Colophony comes via Latin colophonia res ('resin of Colophon') from Greek Kolophōn, an ancient city in Ionia (modern western Turkey) famed for producing superior pine resin. The word entered English in the early modern period, around the late sixteenth or early seventeenth century. It shares its origin with 'colophon', the name of the ancient city that also became the term for a publisher's imprint at the end of a book.
How colophony is actually used
A technical term used chiefly in chemistry, music, printing, and trade contexts; in everyday speech 'rosin' is far more common.
Easily confused with colophony
A colophon is a publisher's or printer's emblem or a note at the end of a book giving production details, whereas colophony is the resinous substance known as rosin.
