Physical properties

• The expression of the interaction of the chemical composition and crystal structure of a mineral

  Physical Property
• The property that describes the way light is reflected off a mineral

  Lustre
• The amount of light that passes through a mineral

  Diaphaneity
• A minerals representation in powder form

  Streak
• The resistance that a smooth surface of a mineral has to scratching

  Hardness
• The way a mineral breaks along its parallel lines

  Cleavage
• The breakage that happens along the planes of structural weakness in a mineral

  Parting
• The resistance that a mineral offers to breaking

  Tenacity
• Any emission of light that is a result of direct heat

  Luminescence
• Ability of minerals to be drawn to a magnetic field

  Magnetism
• Bands of light at 90 degrees

  Chatoyancy
• The minerals that have natural occurring radioactive elements

  Radioactivity
• The effervescence that happens in carbonate minerals happens due to the breaking of C-O bond in the presence of hydrogen

  Solubility
• Interference of light reflects a series of colors representing the interior of the mineral

  Play of colours
• The conductance of electricity that depends on the mineral type

  Piezoelectricity
• Electric charges induced by directed temperatures

  Pyroelectricity
