WebBismuth is a brittle metal with a silvery white color. Its density is 9.7 g/cm 3, its melting point is 271°C, and the boiling point is 1564°C. Bismuth has a number of properties that are decisive for its various applications. It has a low toxicity for humans, and therefore is also called “green bismuth”. http://www.whxb.pku.edu.cn/EN/10.3866/PKU.WHXB20010117 great marlborough street restaurant https://bear4homes.com
