Ballast rock? Or something else

[IndianRiverSonrise]

I found this at one of the wreck beaches and it seemed out of place. I wondered if it was a ballast rock. It seems too light for that to me. It is so porous it seems like a volcanic rock or something. Or maybe just a piece of tumbled coral. I don't know. Any ideas appreciated.

Maybe used for another purpose like scraping off surfaces.

That rock you have looks volcanic,it looks like pumice.If its pumice then it should float in water.

Pumice was used to scour wood decks

It looks like a Pumice stone to me also. As already stated, it could be used to scrub wood decks with. It's also great to rub the bottom of your feet with. It easily removes excess callus buildup and stimulates the nerves in the feet to keep them good and healthy.

My feet are already rubbed rare from walking the beaches barefoot.

Thanks all.

Its not pumice I have found this on a few ballast piles or close to ballast trails, i have larger ones as doorstops I found several years ago and kept because they were out of place, a geologist could answer, maybe I know one that would, just got me thinking, thanks
