From Wikipedia, the free encyclopedia

Abraum salts is the name given to a mixed deposit of salts, including halite ( sodium chloride), carnallite, and kieserite ( magnesium sulfate), found in association with rock salt at Aschersleben-Staßfurt in Germany. The term comes from the German Abraum-salze, "salts to be removed." [1]

Abraum, which is red, is used to darken mahogany. [2]
