I hoped that you would see the thread, Galle. I could not remember your username when I posted the link to your site. It is a very useful site for me.
I ran across the lemon glass in Moser's book last night. It was nice to know from the book and your site that I had not just dreamed some name up. Keith wrote that his glass was not reactive. Something I ran across with a yellow vase this evening is that casing glass somehow can interfere with seeing the UV effect on glass that (I presume) is colored with cadmium. The vase that I tested tonight glowed orange on the iside, which is not cased, but did not glow on the outside, which is cased. I noticed that you pictured the lemon glass on your site inside and outside. I wonder if Keith's vases might indeed be UV reactive, but can't be seen looking from the outside. (I also think that opalescence can interfere with seeing the orange UV reaction, but that is from a different thread.)
When you mentioned the pink vase, were you referring to Keith's or mine? My red vase is really a very dark pink, so thought I would ask.
