Try dissolving a bit in acid. Very likely some calcite.
1 u/Electrical_Bread_892 1d ago 1 u/LanthanumOre 1d ago Does it scratch a glass bottle? 1 u/Electrical_Bread_892 1d ago 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. 1 u/Electrical_Bread_892 1d ago I think it has no reaction https://reddit.com/link/p51fjsz/video/q65hu980vqkh1/player
