I bought and used this approxd 40 mm flat glass spiral disc (small hole in center) recently and have no clude where I got it.  (It is just the glass piece - I added the embelishments around it).  It is glass, came in many different colors and was purchased at the Tucson show.  Help!  Thank you,

It looks like a lampwork piece to me.

Yes, it looks like a lampwork bead to me also.  I know a lot of lampwork artists that make this type of bead, but none measuring 40mm across.  Most are between 10 and 20 mm across.  I wonder if you could find out all the lampwork vendors that were there and narrow it down a bit.  Alice

Fount it - phew - thank you for the help :)

Yep, it's lampwork.  And I know several glass artists who do this shape.  Let me know if you need hooking up.

I do those.  Sounds like you found what you were looking for, but if you need any in specialty colors, I'll be happy to make some for you.
