  3. What is it’s hardness range? 1 - 2 Does it show cleavage or fracture? Hint . . . check out these pictures Cleavage (it is hard to see because the sample is so soft that it gets round edges from being touched)

  4. Outside color? Silver / Grey Inside color – Streak? Grey / Black

  5. Luster – Does it look like metal? Yes, It has a METALLIC luster.

  6. Now use your ESRT page 16 to narrow down a name for your mineral sample.

  7. Luster narrows down your mineral choice to only 4 names

  8. Now check hardness, color and streak
