Yes indeed do times change Roy. I recall back in the late 60s when "nobut a lad" I tried lighting some shafts on the Blythe Mines, Stanton, Derbys, utilising a large heavy saucepan lid, attached to a super long length of string and with some chicken wire-type pocket beneath. Into this was inserted a long coil of magnesium ribbon, which, when lit, and lowered down the shaft was quite a wonder to behold. A sort of Swinging Sixties light painting technique. Regrettably the Brownie Twin Twenty (or similar) did not have a bulb setting so never got any pix! Empirical engineering at it's best :)
.. and this was in the days you could go to your local chemist and buy such items as sulphur, charcoal and saltpetre.. you know the mix ! See (on this site) Photographs of Blythe (Vein & Pipe) Mines Lead Mine. But not the tin lid technique
