I shall dub these "Tangle" I believe they are probably a weak Blue Tang Vacor

[The Nickel Guy]

I must have gotten these (Top half) during a run of Blue Tang making that lacked the sufficient deep blue swirl colored glass and these are more green. I don't think they are a named style of Vacor but if the are, please let me know. For now I shall call them "Tangle". Seems appropriate for the situation they put me in. Pictures are fairly close to color I suppose. Thanks for looking.
