Mineral or Vacor?

Another bunch I don't recall if I ever sent to you. I posted elsewhere awhile back and I believe it was a toss up btw vacor or mineral. Any thots?

They look mineral to me. A super close up would probably reinforce that. If you have a loupe, you can see machinery marks in a glass marble and often inclusions in a mineral sphere.
