Methyl sulfone crystal growth. Polarised light microscopy footage of the formation and growth of crystals of the chemical methyl sulfone (methylsulfonylmethane). The solvent is ethanol. A crystal is a solid material whose atoms, molecules, or ions are arranged in an orderly repeating pattern. Chemicals crystalize out of solution, or dissolve back into solution, depending on conditions such as temperature and solute concentration.
