Keywords: "James Sadd", mineral, "physical property", "chemical composition", "crystal structure", color, cleavage, luster, "chemical reaction", "mineral identification"

Our transcription: Each mineral has a distinctive set of physical properties based on its own unique combination of chemical composition and crystalline structure.
Physical properties include the color of the mineral, the way it reflects light, the way in which the mineral breaks, and some simple chemical reactions.
These are used to help identify the mineral.
