If you crush a lump of St. Peter sandstone in your hand, you won’t see much dust. Does that mean there is no dust, or is it just too fine to see? My wife and I collected some sandstone and brought it back to the studio to investigate, up close.

As I was transferring the sand from one container to another, it took me a minute to realize why I was coughing. No dust in sight. Later, against a black background,
in a bright light, the dust swirled and sparkled and hung in the air for a long, long time.

The sand itself is remarkably uniform, and very different from sandbox sand. My brother, who studied geology, tells me that this sand is ancient.
