The 6 characteristics:
1) hardness
2) cleavage and fracture
3) colour
4) lustre
5) crystal structure
6) streak
Hardness:
Hardness is a measure of the minerals resistance to being scratched and diamond is the most hardness rock.
Colour:
Colour is one of the most attractive properties of a mineral and colour helps identify a mineral. Whenever two or more minerals may have the same colour depending on what colour is inside the mineral and the colour can be different.
Streak:
Whe a mineral is rubbed across a peice of unglazed tile, and it leaves a streak. The streak is the colour of the powdered form of the mineral. Did you know that a tile has a a hardness of 7 minerals that have a hardness greater than 7 do not leave a streak on the tile.Streak is the color of the powder of a mineral. The mineral streak, rub it on an unglazed porcelain tile. The color left on the tile is the streak.
Lustre:
Some minerals, such as gold and silver appear, shiny, and another clue to their identify.
Cleavege/Fracture:
The way a mineral breaks apart is another clue to identify a mineral. If a mineral breaks along aplane smooth flat surface it is said to have cleveage. For fracture not all minerals have cleavege minerals that break with rough or jagged edges have fractures.
Crystal Structure:
A crysatl structure has straight edges, flat, sides, and regular angles.The 6 crystal structures are.
