The octagonal room hosts a winch called "crivac" or "gepel", rudimentary machinery used to lift salt rocks on the surface. It dates from 1881. This machine replaced another, smaller in size, that was installed in 1864. It is the only machine of its kind, in all the salt mines in Romania and probably in Europe, that remains in its original location.
X-ray spectrometer developed by W. H. Bragg. In 1913 the structure of sodium chloride was determined by William Henry Bragg and his son William Lawrence Bragg. [2] [3] [4] This revealed that there were six equidistant nearest-neighbours for each atom, demonstrating that the constituents were not arranged in molecules or finite aggregates, but instead as a network with long-range crystalline ...
The Solvay process or ammonia–soda process is the major industrial process for the production of sodium carbonate (soda ash, Na 2 CO 3).The ammonia–soda process was developed into its modern form by the Belgian chemist Ernest Solvay during the 1860s. [1]
