There have been some experimental uses of carbon paper in art: as a surface for painting and mail art (to decorate envelopes). Carbon paper is commonly used to transfer patterns onto glass in the creation of stained glass. [7] Carbon paper disks are still used in school physics labs as part of experiments on projectile motion and position. [8]
A copy made with carbon paper. Before the development of photographic copiers, a carbon copy was the under-copy of a typed or written document placed over carbon paper and the under-copy sheet itself (not to be confused with the carbon print family of photographic reproduction processes). [1]

The image transfer medium was originally a stencil made from waxed mulberry paper. Later this became an immersion-coated long-fiber paper, with the coating being a plasticized nitrocellulose. This flexible waxed or coated sheet is backed by a sheet of stiff card stock, with the two sheets bound at the top.
To dampen the tissue paper, the clerk used a brush or copying paper damper. The damper had a reservoir for water that wet a cloth, and the clerk wiped the cloth over the tissues on which copies were to be made. As an alternative method of dampening the tissue paper, in 1860 Cutter, Tower & Co., Boston, advertised Lynch's patent paper moistener.
After a 10-second exposure, the paper was directed to developing and fixing baths, then either air- or machine-dried. Since the print was directly exposed, without the use of an intermediate film, the result was a negative print. A typical typewritten document would appear on the photostat print with a black background and white letters.
