About Sulfurite
Formula:
S
Colour:
brown, yellow, yellow-grey
Specific Gravity:
2.0
Crystal System:
Amorphous
Name:
For the elemental composition, and to differentiate it from normal alpha-sulphur.
A mixture of metastable allotropes of native sulphur which slowly reverts to crystalline alpha-sulphur. Formed when liquid sulphur is rapidly quenched (as when a sulphur flow runs into water). The composition of the mixture depends on the temperature and age of the liquid when quenched and is usually dominated by long helical chain molecules that are the cause of the plasticity of the sulphur, with about 3 atoms per spiral. Initially elastic, soon gets brittle due to crystallization of the S8 contained in the mixture.
