Question

"Today you will use this chart to help you identify some common minerals," instructed Mr. Grant, Jimmy's teacher. Each group of students was given three mineral samples to identify. Jimmy and his partners were puzzled by one sample. It scratched glass, so it was pretty hard. One student thought it was feldspar; another thought it was quartz. What other properties could the group use to identify the mineral?

Answer 1

The properties of minerals that might help Jimmy and his partners to identify the sample other than Hardness (scratch test) are:

1. Color

2. Crystalline Structure

3. Cleavage or Fracture

4. Transparency

5. Tenacity
