Alum red, KAl (SO₄)₂ x 12H₂O
Alum with the formula KAl (SO4)2 x 12H20 crystallizes in
a regular crystal system. Although it is easily solvable in water, in the natural environment it does naturally form crystals and crusts. This Alum is created in a lab in Poland using the hydrothermal method. Usually Alum is colorless but color can be added through water. When put into direct sunlight it loses that water from its composition and turns white. Alum is also used in cosmetics to stop bleeding and to accelerate the general healing process.
