The surplus brine of Berchtesgaden is conducted to Reichenhall, and thence, in increased volume, to Traunstein and Rosenheim, which possess larger supplies of timber for use as fuel in the process of boiling.
In the former case it is often difficult to obtain the brine at a density even approaching saturation, and chambers and galleries are sometimes excavated within the saliferous beds to increase the dissolving surface, and water let down fresh is pumped up as brine.
Through this space the fresh surface water finds its way, and dissolving the salt below rises in the inner tube as brine, but only to such a level that the two columns bear to one another the relation of ten to twelve, this being the inverse ratio of the respective weights of saturated brine and fresh water.
Krohnke into Copiapo, Chile, in 1860, the silver mineral of the pulverized ore is decomposed in a revolving barrel by a hot solution of cuprous chloride in brine in the presence of zinc or lead and quicksilver (see B.
Jn 1841 natural gas was found with salt brine in a well on the Kanawha, and was used as a fuel to evaporate the salt water.
During the rapid formation of ice the still unfrozen brine is often imprisoned between the little plates of frozen water; hence without some special treatment sea-ice is not suitable as a source of drinking water.
It is well known as a health resort, for the grape cure and for the baths of the brine springs of Philippshalle, in the neighbourhood, which not only supply the bathing establishment, but produce considerable quantities of marketable salt.
The brine conduit to Traunstein dates from 1618.
Rosenheim is frequented for its saline and sulphur baths, and there are important saltworks, the brine being conveyed from Reichenhall in pipes; it has also machine factories, metalworks and breweries.
The brine springs of Reichenhall are mentioned in a document of the 8th century and were perhaps known to the Romans; but almost all trace of antiquity of the town was destroyed by a conflagration in 1834.
