Gutta-percha refers to trees of the genus ''Palaquium'' noted for their latex as well as the rigid natural latex produced from the sap of these trees, particularly from ''Palaquium gutta'' but also ''Isonandra gutta'' and ''Dichopsis gutta''.〔https://books.google.com/books?id=OytJAAAAIAAJ&lpg=PR19&ots=GBqkR2V1XD&dq=dichopsis%20gutta&pg=PR19#v=onepage&q&f=false〕 The word ''gutta-percha'' comes from the plant's name in Malay, ''getah perca'', which translates as "percha sap". 'Discovered' in 1843; found to be a useful natural thermoplastic, in 1851 of gutta-percha was imported into England.〔 During the second half of the 19th century, gutta-percha was used for myriad domestic and industrial purposes, and it became a household word. In particular, it was needed as insulation for underwater telegraph cables,〔(Gutta-Percha company )〕 which, according to author John Tully, led to unsustainable harvesting and a collapse of the supply.〔 http://muse.jhu.edu/login?auth=0&type=summary&url=/journals/journal_of_world_history/v020/20.4.tully.html〕 ==History== A brief history: 'Even long before Gutta-percha was introduced into the western world, it was used in crude form by the natives of the Malaysian archipelago for making knife handles, walking sticks and other purposes. The first European to discover this material was John Tradescant, who collected it in the far east in 1656. He named this material “Mazer wood”. Dr. William Montogmerie, a medical officer in Indian service, introduced gutta-percha into practical use in the West. He was the first to appreciate the potential of this material in medicine, and he was awarded the gold medal by the Royal society of arts, London in 1843' 〔(Gutta-Percha - An untold story.
