Magnesium Sulfate, Epsom Salts


Ask us a question

Colorless transparent crystals that are easily dissolved in water. Magnesium sulfate is commonly used in ceramics as a flocculant. It thickens and gels suspensions by electrostatically charging particles so that they attract each other more. This not only suspends them in the slurry but makes them stay put on non-porous surfaces (by virtue of the gelling mechanism). Even slurries containing no clay particles can be flocculated using this material.

Chemical Formula: MgSO4

Synonyms: Magnesium Sulfate, Epsom Slats
