Glass Chatroom Board

@itsagas : About the only information on Dugan Art Glass out there is what's on Dave Doty's site, The Loetz.com site and in Heacock/Measel's book on Dugan Glass. And it isn't much. There is just very limited information on it known. If the person who posted that on the PG&P board simply checks those three sources, they'll have just about as much information as is available.

I looked at your iridescent bowl. My best guess, based on what I could see, is that it's likely Dugan/Diamond. The only ones that made an Amethyst "stretch" of that dark a shade are Dugan/Diamond & Vineland and it really doesn't llok much like Vinelands stuff. Northwood, Fenton & U.S.Glass all made Amethyst Stretch, but usually in a much lighter shade, more like a Wisteria or Lavender tone.
