Title: Hoping this bowl colour is real amethyst.
Post by: Paul S. on October 05, 2010, 08:59:24 PM
having recently made a faux pas with what I thought was deliberate purple glass - I am submitting the attached picture in the belief that this bowl is a genuine amethyst colour  -  but, of course, I may still be wrong. :)  Diameter is 5.5"/about 140mm - and with a good quality flat, ground, outer rim to the base (similar to older pieces - although there is not a great deal of wear to this bowl).   I think the colour is beautiful, and feel it must be genuine, so would appreciate anyone's opinion please (or hopefully an attribution and confirmation).    Thanks for looking.   Paul S.

 :hi: Paul S.

I know nothing about your bowl, but I am wondering *IF* it could be what they call SUN PURPLE ?
http://www.patternglass.com/sunpurple.htm

The only reason (why I think that) is that I thought (??????????????) Real Amethyst color in glass is quite a bit darker.  Now, this is coming from me -- SO please take that with a grain of salt because I am merely thinking-out-loud here   LOL    .....and not really sure about what I even just said  :24: ;D :24:

So this is just a WILD guess here -- that maybe the glass is Sun Purple....but ask someone with way (way, way, way) more knowledge than me.....

 :ooh:

It does look like sun purple to me too.   :-\   It's not a bad thing...people collect sun purpled glass.  I think I sold some Fostoria once like that and when I sold it, it achieved more than usual.

Rose and Max, thanks, but no, no, you've got it all wrong  -  surely it has to be amethyst - it looks so 'right' and the colour is delicate and pale  -  there isn't a darkening to the glass like what my candlestick was showing ;)     But seriously, the problem with this bowl, is that whilst the ground outer foot rim would indicate it is an 'oldish' piece, the whole thing lacks wear, and so I'm somewhat confused, but the tint really is colourful.   I will have to go through Pamela's photo gallery again, as I would like to find a name or an attribution for it.
Correction to the wording of my opening lines, which should have read............"a faux pas with what I thought was real amethyst glass"...............

I think Paul is right. This looks mid 20th century piece (post War, pre-modernisation) to me, perhaps from a company like VSL or one of the Sklo Union companies.

thank you so much Christine and especially Pamela  -- always embarrassing when it appears in books that I actually possess. :-[
So, what produces the amethyst colour in this instance please. :)

Try your UV light on it, and you may have the answer, but there are undoubtedly several other options.

I'm sure there was once such a desire for sun-purpled glass that some crooks in the states were deliberately setting pieces out on the roofs of buildings in bright sunshine to accelerate the process and boost sales.
Sorry, I can't remember where I heard that, I'm pretty sure it was here, in a long discussion.
It may be in the Archives, given there was a lot of interesting stuff came out in that thread.  :thup:

ta-da!

Paul, I am currently srtruggling to read or type ANYTHING, relying completely on auto-pilot and residual adrenalin from the Scottish Glass Conference for everything. It snot fair to be bad to me, only trying to hwelp,. snifgf.  :cry:

whoa (I think that means halt, or some such similar meaning Sue)  -  heavens, I was never meaning to be serious - sorry if it came across rather heavy. :)  -  I'm the one who overlooks these things usually.   Couldn't even find this bowl in my own books - how dim is that.   There, there, now dry your Scottish eyes, and apologies from a Sassenach. ;)

I feel very sorry for antbody who wasn't there. ;D

here are the results of uv light reaction on this bowl  -  so am guessing selenium  -  which apparently when used alone produces a pink colour in soda glass.   Am I on the right lines?? :)
