Identify

Start with what you can observe.

A photograph is useful context. Hardness, luster, streak and a few careful tests narrow the next question. This worksheet suggests observations; it does not make a definitive identification.

Specimen clues

Test an inconspicuous spot. Wear eye protection.
Do not use chemicals without suitable supervision and protection.

Your next observation

Choose the clues you know. The worksheet will show what to check next and let you carry the notes into your Journal.

Compare candidate minerals with a field guide or a qualified local expert before labeling a specimen.
