What are the 8 physical properties of a mineral?
Some minerals can be identified with little more than the naked eye We do this by examining the physical properties of the mineral, which include: Color: the color of the mineral Streak: the color of the mineral’s powder (this is often different from the color of the whole mineral) Luster: shininess Density: mass per volume, typically reported in "specific gravity," which is the Introduction Unlike other physical properties, the densities of the commonest rock forming minerals are remarkably close together The actual densities of pure, dry, geologic materials vary from 880 kg/m 3 for ice (and almost 0 kg/m 3 for air) to over 8000 kg/m 3 for some rare minerals Rocks are generally between 1600 kg/m 3 (sediments) and 3500 kg/m 3 (gabbro)Densitygross sample – a quantity of powder, adequate for the tests to be performed, consisting of all powder density in g/m3, 2 i is the variance of the tolerated sample error, 1 is the fractional mass of the w coarsest size class being sampled and 1 d 3 is the arithPowder Characterization and Testing ElsevierAre you looking for the bulk density of the powder or true particle density?

Measuring mineral density Now you will check your estimate of the relative densities of the minerals by measuring the density of each mineral The way you measure density is to divide the mass or weight of a sample by its volume Written out, the formula for calculating density is: D = M/V where D = density (g/mL), M= mass (g), and V=volume (mL)For these minerals, a streak test can be obtained by powdering the mineral with a hammer and smearing the powder across a streak plate or notebook paper While mineral surface colors and appearances may vary, their streak colors can be diagnostically useful An example of this property is seen in the ironoxide mineral hematite36: Identifying Minerals Geosciences LibreTexts
