If not too embarrassing, I'd like to hear that story!


Oh! Nothing serious or whatever.
All you need to do is keep the anode and cathode a distance away from each other and collect the bubbles coming up from each, one was pure Hydrogen, the other pure Oxygen. As my last chemistry lesson was well over 50 yrs ago, can't remember which is which, but it's not a good idea to mix the two in quantity as they tend to go bang!
No sure about coal but there was lead mining in the South Shropshire Hills dating form Roman times but possibly in permenet production form the 11th Century ...Chops wrote: ↑Wed Aug 17, 2022 5:51 amMoreover, it is possible that a British mine might have been digging out coal for several, or many, centuries in the same spot. Conversely, American mineral deposits are relatively recent (within the last century) and the trend was to exhaust one vein and travel down the road to the next, with little attention to any sort of permanence.
There was coal mining in Cheshire too, at least of you can still count The Wirral as Cheshire like wit was when i was a lad. The Neston collieries dated from 1855 until 1927. I 'discovered' them while reseach the station at Park Gate, where my mother's family had their annual holidays before and after the war, travelling by train from their home in New Brighton (Wallasey) - all of 12 miles being long haul in those days I guess! In 2019 I went there in the company of my now very elderly aunt who is now succumbing slowly to Alzheimer's. Recalling the visit a few months ago over the phone I quized her about these train jourmey's, "Change at Hoylake!" was her quickfire response - made my day it didcheshire lines wrote: ↑Tue Aug 23, 2022 8:10 pmThe area of Cheshire where I live was well known for salt mining, particularly in the 19th century. This led to a lot of subsidence with some buildings collapsing into holes in the ground and others where what was the upper floor now being the ground floor.
There is still one salt mine open at Winsford which supplies rock salt for treating roads
In icy weather. Unlike coal mines, the tunnels are huge, with roadways with full sized lorries (trucks) running down there.
In addition to the one remaining mine, salt is also extracted by brine pumping to supply the local chemical factories.
The fields around our village are dotted with.small pumping stations and every now and then we see a mobile drilling rig sinking another bore hole.
