The History of Sandpaper........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 also used as a sandpaper. The rough scales of the living fossil Coelacanth are used by the natives of Comoros as sandpaper.[2] Boiled and dried, the rough horsetail is used in Japan as a traditional polishing material, finer than sandpaper. Sandpaper was originally known as glass paper, as it used particles of glass. Glass frit has sharp-edged particles and cuts well; sand grains are smoothed down and did not work well like sandpaper made from glass. Cheap counterfeit sandpaper has long been passed off as true glass paper; Stalker and Parker cautioned against it in the 17th century.[3] Glass paper was manufactured in London by 1833 by John Oakey, whose company had developed new adhesive techniques and processes, enabling mass production. A process for making sandpaper was patented in the United States on June 14, 1834 by Isaac Fischer, Jr., of Springfield, Vermont. In 1921, 3M invented a sandpaper with a waterproof backing, known as Wet and dry. This allowed use with water, which would serve as a lubricant to carry away particles that would otherwise clog the grit. Its first application was automotive paint refinishing.[4] :)
