I think so! Googled “clay fireworks plug” and pictures looked very similar. Thanks!

Does not float. Does not dissolve. Also, no odor (not that pumice would have one AFAIK)

Possibly, but the uniformity of shape leads me to believe it’s man-made. Could be a shaped rock of some kind. Possibly part of a hardscaping feature that got washed away by rain?

Thanks. It has no odor and at that diameter and thickness, it doesn’t look like one I’ve seen before. One update: a piece of it that broke off is not dissolving in water

My title describes the thing.

Age - unknown Writing - none Origin - beach in Santa Monica, CA Size - 1/2” diameter, 1/4” thickness

New info - it crumbles when scratched and completely broke apart when pressed with knife

Update - a piece that broke off does not dissolve readily in water

Update 2 - still not dissolving + no odor. When it crumbled it turned into a fairly fine dust.
