78.63.50Description
Chemical Composition: S
Crystal System: Orthorhombic System
Description: Common Name: Sulphur
Chemistry: S
Group: Polyatomic Non-metal
Location: Sicily, Italy
Description: A small specimen with multiple large crystals in the center.
Physical Charateristics:
•Color is a strong yellow color in thick crystals and duller yellow in small crystals to pale yellow in massive or powdery forms. Can also be reddish or greenish yellow with impurities.
•Luster is vitreous to more often resinous or earthy in massive forms.
•Transparency is transparent to translucent.
•Crystal System is orthorhombic; 2/m 2/m 2/m
•Crystal Habits include mostly massive or powdery forms but well shaped blocky crystals are common. Crystals can be made up of two dipyramids, one with steeper faces than the other, prisms and/or pinacoids in various combinations.
•Cleavage is very poor in two directions.
•Fracture is conchoidal.
•Streak is yellow.
•Hardness is 2.
•Specific Gravity is 2.0 - 2.1 (well below average)
•Associated Minerals are celestite, calcite, aragonite and gypsum.
•Other Characteristics: odor (see above), poor heat conductivity makes it brittle when heated and can actually crack if held tightly in a person's hand.
•Notable Occurrences include Michigan and Ohio, USA; Sicily; Poland and Chile.
•Best Field Indicators are color, odor, heat sensitivity, lack of good cleavage and crystal habit.
