Researchers at Nanyang Technological University have invented a near-invisible coating that makes wood fire-resistant, whilst retaining its natural beauty. Once heated, the chemicals in the coating react, turning into a black char and expanding to more than 80 times the original thickness. The blackened exterior prevents fire from consuming the wood underneath. It costs around $2 to cover a square metre of wood. NTU is in talks with several companies to licence the technology.
