Bruce,
Am not sure what you mean. The three pits (brine springs)
we have details for that were exploited for salt were of different
depth (Netherwich 18ft, 18ft, Upwich 30 ft). But the brine solution
channel below the gypsum was at about 150 ft. at Droitwich; whereas
at Stoke which were man-made boreholes sunk in shafts, the brine run
was 800 ft. deep. The source of the water to the best of my knowledge
is the same, i.e. the Lickey's. Do you have other information?
There was an alkali company at Stoke originally, and I believe
a small attempt at mining, but there was water seepage and it was not
until Corbett came along and made the boreholes watertight that it was
economical to exploit the brine. That was about 1856 or thereabouts if
my memory serves me right.
Any news from your friends at Droitwich?
