Principle

In this experiment, the properties of the sulfur are
investigated.
For this purpose, the sulfur is heated to the melt in the first
experimental part (monoclinic and rhombic sulfur), and the habit of
the crystals formed is observed during the cooling.
In the second experimental part (crystallization of rhombic
crystals from a sulfur solution), sulfur is dissolved in sulfuric
carbon, and the crystallization of the sulfur is then observed upon
evaporation of the solvent.
In the third experimental section (behavior of the melt on further
heating and in the case of sudden cooling), the material properties
of the resulting amorphous sulfur are observed.
