SC - period salt

[Edgar, Terry]

There were many salt mines in operation in the middle ages.  There is one
that is still located in eastern europe( I can't recall the country).  This
mine was used so extensively in the middle ages that a chapel was carved out
of the salt for the workers to worship at.  This mine is still operational.
I saw a television show on it on the history channel (I think)  The chapel
was amazing with life sized figures all carved out of salt. The chapel was
located deep underground.  I would assume that salt was exported so I would
imagine that salt came from other sources than Rome.

My understanding of geology is that salt mines are in ancient sea
deposits, so the salt would still be 'sea' salt. The actually mineral
content would vary from area to area, and depend also on when the
deposit was formed. One benefit of mining salt rather than evaporating
it is that ancient salt is probably clear of any pollution or waste
runoff coming from a settled area nearby, unless groundwater is carrying
it in. 

The two current methods for mining salt is 'room and pillar' which is
much like it sounds, mining out 'rooms' in the deposit, leaving
'pillars' to hold up the ceiling. The other method is to drill into the
deposit, pump in water to dissolve the salt, and pump out the brine.
Much like the Romans were, except they didn't have to pump in the water
after digging down far enough.
