Steve Herschbach Posted August 19, 2015 Share Posted August 19, 2015 I have never heard of this stuff before. Blue John is a very rare form of blue banded fluorite fashionable in 1800s England. What also caught my eye in the article was the use of an experimental chainsaw for cutting rock underground. http://www.bbc.com/news/uk-england-derbyshire-33984792 There is a good Wikipedia article on Blue John at https://en.m.wikipedia.org/wiki/Derbyshire_Blue_John along with this photo of a bowl made from the material. 3 Link to comment Share on other sites More sharing options...
