Fire has been a nightmare for paper historical relics. Researchers with Shanghai institute of Ceramics, Chinese Academy of Sciences, have developed a new paper which is resistant to fire. Even under 1,000 degrees Celsius, the paper will not burn. They made this new substance from calcium phosphate compound. The research was published in "Chemistry - A European Journal" on Jan. 27, 2014.
This novel kind of inorganic paper is flexible and incombustible, but still feels like ordinary paper. It can be torn, folded, and destroyed by strong acid. It can be used for important documents – preserving them for prolonged periods of time.
