Feldspar

Feldspar is a milled crystalline anhydrous sodium potassium aluminium silicate. It has a high dry brightness, high hardness, good heat stability, is inert and is easy to disperse. The main application for Feldspar is as a general filler in self-levelling floor screeds, paints, polymers, adhesives, polishes and rubbing compounds.

Hint: to highlight K-feldspar, switch to a medium or low magnification objective (usually 4 or 10X works well), mostly close the substage iris, and raise the stage slightly (yes, raise). Though the image will be somewhat out of focus, the low index K-feldspar grains will be surrounded by bright Becke lines just inside the grain boundaries.
