 Rystals and Minerals

In the Crystal Growth Lab. we made a experiment for the minerals with water. Then letting the crystal grow and wait for the time to let the crystal grow.The minerals became the crystal.Then we need to learned  luster, color, streak, hardness, cleavage, fracture, And to judge。

Mineral properties

                                         Metallic luster: the mineral look like metal

color: how does a mineral look

Non-metallic luster：the mineral doesn't look like metal

cleavage: a mineral that breaks evenly in the surface.

fracture: a mineral that breaks unevenly,(wave)

Hardness:the hardest mineral and the softest mineral
