No need to apologise Della, such a long thread with so many points of view.
I was kinda saying your blue vases (good photos) deserved an attribution - I have a had a closer look at pics in your files and you are right about the large green piece being Ingridglas, but you know that already - your blue vases do have a very thin rim and wall structure, never spotted that in the posted photos - I take back Ingridglas even though the slumped textural effect is similar.
I have W/F coffin vases but no actual straight sided bark vases till early next week.

link Can someone post a picture for this sweet lady - pewter or flint works best I feel, tangerine and ruby, etc. feed too much colour back.
I have tons of bark vase pictures, but none of the bases (yet I am sure I have taken some when the number sticker was still attached :? ) - mmmmm, I must store a few when I get some in.
