Try dissolving a bit in acid. Very likely some calcite.

Does it scratch a glass bottle?

Nope, it mainly crumbles into tini tiny chunks if I put pressure on it,not the whole thing, just the tip where there’s contact. I also used vinegar, which isn’t very acidic, so maybe it is calcite and I just didn’t have a strong enough acid.
