General Information
The undecahydrate is stable at low temperatures in contact with a saturated magnesium sulfate solution. At temperatures above 0 °C it melts incongruently, resulting in epsomite and water. [Steiger.etal:2011a]Author: Steiger, Michael; Linnow, Kirsten; Ehrhardt, Dorothee; Rohde, Mandy
