New Blue John Discovery


Recommended Posts

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.

Yeah Steve I have used those ChainSaws they Have Oblong straight Diamond Teeth on them about the size of those on A 3/8 Chainsaw including the Raker, They Are powered by Water and The Chain is cooled by Water and are powered by about A 7.5 HP Motor and an Inch+ water combined water Pump, At work we Had 3,,, 2 were stolen within the first 6 months they have about a 24 to 26 inch bar on them and sound Like A Quiet MACK Air Start, somewhere I still have some of the old Chains, I was using them to Cut rectangular holes in concrete Walls For Drainage. I was using them Back in 2004
