Synthetic carnallite crystal specimens can be produced from 1.5 mole percent KCl and 98.5 mole percent MgCl2·6H2O by slow crystallization at 25 °C. Its density is 1.602 g/cm3. Carnallite can also be produced by grinding the combination of hydrated magnesium chloride and potassium chloride.
How is carnallite formed?
Carnallite is named for Prussian mining engineer, Rudolph von Carnall. It forms in marine evaporite deposits where sea water has been concentrated and exposed to prolonged evaporation.

What is the natural source of carnallite?
Carnallite occurs with other chloride minerals in the upper layers of marine salt deposits, where it appears to be an alteration product of pre-existing salts. The mineral is found principally in the northern German salt deposits; and also in Spain, Tunisia, and the southwestern United States.
