What it is?

Epsomite is a magnesium sulfate hydrate. It forms with seven water molecules for every magnesium sulfate molecule. It is a common evaporatic mineral that was first identified in the caves of Epsom in Surrey, UK in 1816. Then it was first called Epsom salts and became a nice thing to put in your bath to ease aches and pains. But it's also thought to be found on the moons of Jupiter!

Where did the structure come from?

Epsomite is #1100091 in the Crystallography Open Database.
