Sand





This is a tiny pinch of sand washed from the clay across the street.

Particle size is very fine and uniform, about 0.25 millimeters diameter. On the right side of the middle photo you can see a human hair. This is much finer than most beach sand.

It is nearly all quartz with some magnetite and a bit of garnet and feldspar.
