Anhydrous magnesium sulfate
From DMT-Nexus Wiki
Anhydrous magnesium sulfate (MgSO4) is a hygroscopic drying agent often used in freebasing[1].
It can be retrieved from Epsom Salt[2] (MgSO4 · 7H2O), which is commonly used in salt baths.
MgSO4 · 7H2O → MgSO4 · 1H2O at 150°C
MgSO4 · 1H2O → MgSO4 at 200°C[3]
The anhydrous form is soluble in water, slightly soluble in alcohol, and insoluble in acetone at 20°C[4].
