Pumice perhaps.

I was thinking against that, only because of it's high density.

Doesn't float then? In texture and weathering it looks a little like a limestone or chalk. How hard is it? Can you get hold of any dilute hydrachloric acid? If it's limestone it should fizz.

No it doesn't float so it's pretty solid! :biggrin:

No, I can't get any dilute hydrachloric acid any time soon, I'm off campus visiting home.

What state was it found in? Was it found in a field, a river bed? Is the surface hard and smooth as opposed to rough? Does it feel sandy or porous?

I have picked a lot of limestone off the breakwater between Tampa and Clearwater, and found a lot of fossilized sea-critters. I also found some limestone with small voids in it, not unlike the pix in the OP.

Try to scratch it with Your fingernail, a penny and a steel knife. If it's limestone it should scratch easily with the penny and the knife but not your fingernail.

My reply: It does scratch into a fine white powder when scratched with a penny. Also, when I scratch with my fingernail a smaller fraction of the white powder is produced!

Do you think it's not limestone then?
