Sandpaper
History
The first recorded instance of sandpaper was in
13th century China when crushed shells, seeds, and sand were bonded to parchment using natural gum.
Shark skin was used as a sandpaper. Sandpaper was originally known as
glass paper, as it used particles of glass.
The rough scales of the
living fossil Coelacanth are used by the natives of Comoros as sandpaper.
Glass paper was being manufactured by
John Oakey's company in
London by
1833, who had developed new adhesive techniques and processes that could be mass-produced. A process for making sandpaper was
patented in the
United States on
June 14,
1834 by
Isaac Fischer, Jr., of
Springfield, Vermont.
In 1916
3M invented a type of waterproof sandpaper, known as Wetordry™, and its first application was for automotive paint refinishing.
