They call it blue ice I think I think sometimes they call it blue fire ice or something. It was really big two years ago being sold as Indonesian material but it is definitely man-made.
Oh interesting, thanks! I found “Blue Ice Glacierite” online and it sure does say that the mineral was found in Indonesia, and then put through the smelting process. So I guess it’s like slag? Unlike the beautiful Leland Blue, that Blue Ice must be in unlimited supply, hence your buddy‘s video about it being man-made (I’d love to watch it). I agree it’s pretty cool. Saw some vids and the white sprays almost look like scolecite, but it’s a shame many sellers are passing it off as the very rare and naturally occurring Nakauriite from Japan🙈
