You may have used your fingernail on talc or mica.  You may have used a paper clip or a penny as well in helping identify other minerals.  You wouldn't have any tools to use on other minerals.  What property are you using? 

• Cleavage
• Streak
• Hardness
• Luster

How a mineral reflects light is another property to identify minerals.  A mineral with metal reflects light and would be metallic.  A mineral without metal will be dull or clear.  It is nonmetallic.  What property is being used? 

• Luster
• Touch
• Streak
• Cleavage

• 1
• 5
• 6

How do you test the hardness of a mineral?
