A carbon copy, literally speaking, is a copy of a document made by using carbon paper. Carbon paper is paper coated with black carbon ink and wax. This is placed between two sheets of paper so that the black ink is transferred to the bottom piece of paper when the top piece is written or printed on. Originally, black soot (hence, carbon) was used for the black pigment. This method of making document copies is all but extinct, today, but was once ubiquitous. The term still survives in idiomatic form as well as in the abbreviation, c.c. used on letters and other correspondence, which is used to indicate that the same document is being sent to someone else.

Origin
Carbon paper, described above, was patented as part of the Manifold Stylographic Writer System, invented by Ralph Wedgwood in 1806. Designed to make simultaneous copies of handwritten documents, the system was later marketed simply as a ‘copy book’ or ‘Stylograph.’ Copies made using this system came to be known as carbon copies, a term that passed into general figurative use by around 1870.
