Sorry, no etymologies found.
Eager to see this new world for themselves, people purchased small brass eyepieces called spinthariscopes, named for the Greek word for spark.
Anyway, when I wrote an article about spinthariscopes for my Popular Science column, I needed a way to show in print what the inside of a spinthariscope looks like.
Modern uranium ore or americium button-based spinthariscopes are not dangerously radioactive and the sources are well sealed, but still.
Which I swear is what I remember seeing in real spinthariscopes until someone pointed out that of course at those dim light levels you can’t see color at all.
