For everyone who was asking....
I took a close look at all five of the little pieces of the 'butterfly' glass I have (the largest one is a little bigger than my palm...and I only have one that large), I can say with some confidence that it is, indeed, the Fremont glass.
One-It just plain looks like the same glass.
Two-There is some variation in thickness, though it isn't too pronounced over such small scraps.
Three-The clue that really clinches it, there is a half of a tag from the dealer on it that says "Frem (then the take breaks off) and on the next line "mu" (and again the tage breaks off). I think that is a pretty clear sign.

Thanks again!
Great that you've had a chance to work with it Lynn. Veeeeeery pretty glass:)
it is really pretty glass and although it's expensive it just adds that WOW factor to whatever you put it in.
