11 - -Optical PropertiesOptical Properties::

• a) Colour ( blue – green – red – colourless – colourless with tint ……

• b) Lister divide into two section * Metalic * Non-Metalic

Non-Metalic may ( Vitreous – Resinous – Earthy – Girassy )

• c) Streak (May the colour of powder not the same colour of mineral)

• d) Transparency divide into three section *Transparent - Semitransparent – Opaque*

22 - -Cohesive PropertiesCohesive Properties

• a) Hardness (1 – 10)

• b) Cleavage ( present – absent )

• c) Parting ( present – absent )

• d) Tenacity ( hard – brittle )

• e) Fracture ( even – uneven – concoidal )
