A rough measure of mineral hardness can be made by assembling a kit of handy objects (table 6). A fingernail has a hardness ranging from 2 to 2.5, a penny is a little harder than 3, window glass ranges from 5.5 to approximately 6 in hardness, and a ...

Apatites are calcium and phosphate containing minerals with the general crystal unit cell formula Ca 10 (PO 4) 6 X 2 where X = Cl, F, OH.

By means of a simple cadmium sulfide photoconductive cell, the spectral reflectivities of about 200 opaque ore minerals, mostly oriented, have been determined in air at wavelengths of about 470 mmu (blue), 520 mmu (green), 575 mmu (yellow), 600 mmu (orange), 700 mmu (red), and in white light ( approximately 610 mmu ).

The physical characteristics of minerals include traits which are used to identify and describe mineral species. These traits include color, streak, luster, density, hardness, cleavage, fracture, tenacity, and crystal habit.
