Abstract
The use of reflected light microscopy to study industrial minerals has been largely overlooked and neglected. Industrial minerals are much darker than ore minerals, and this property has tended to dissuade most microscopists from studying industrial minerals in polished sections under reflected light. Furthermore, the reflectance (R) values for most industrial minerals are not listed in standard reference works. The most useful property of industrial minerals for their identification under reflected light is their reflectance (R). The reflectance of most industrial minerals ranges from 3 to about 9. This range is similar to Portland cement clinker phases and brighter than coal macerals. This communication provides reflectance values for some of the common industrial minerals, and provides some examples of the character of industrial minerals as viewed under reflected light.
