If cooling is slow, large crystals form If cooling is fast, small crystals form Minerals can form from solutions Water can evaporate, leaving mineral crystals behind Minerals can precipitate from a saturated
solution Mineral Identification Luster (metallic or nonmetallic) Mineral Identification Color (not always reliable for identification)
Mineral Identification Streak color (scrape against a ceramic tile) Mineral Identification Hardness (how easily it is scratched)
Mineral Identification Cleavage/fracture (does it break evenly or with jagged edges Mineral Identification Texture How does it feel? (smooth, rough, glassy,
soapy, greasy) Feel these minerals: Quartz (smooth/glassy) Graphite (greasy) Talc (soapy) Mineral Identification
