Topic: Blue/green bowl with lenses — id help please

[Scott13]

 

  Hi,
  I’m half expecting this to come back as modern, machine made and mass produced—after having said though, it has got a fair amount of wear on its base and there’s also a bit of cloudiness inside...........

  It seems quite light for its size —378gm.
   Ht—10cm ( 4” )
    Diam—12.5cm ( 5” )

   Its colour is a deep blue/green.

   Any help in identifying it greatly appreciated—many thanks for looking

  Sorry should have described it as a vase

Have a (very) vague feeling this might be from one of the German glass makers.

Maybe not, I was thinking of Gistl, like this:

It's different to Gistl, which has hot worked coloured glass over the surface.
The colour reminds me of my "Darth Vader" vase. The thread on that is quite long.

on the second page, there is a link John found which might be of some use.

  I’ve tried everywhere again to see if I could find a match—but no, no luck.
  I can see why your memory bank threw up Gisti, John,
but like Sue I can see that it’s different.
 Of course I’ll keep looking............
 
  Interesting links Sue — not sure what glass plastic is though

Plastic as a word, just means malleable. When glass is hot, it becomes plastic.
It is also (correctly) referred to as a metal. That just refers to how it behaves too. 

I do think your lovely vase is this same unusual and rather spectacular colour.
I still feel mine is of bohemian origins, because of the quality of the mould and the relatively few pieces around.
It's only the big factories there and at that time, who could afford to make such a good quality mould and subsequently not to have it used terribly often. 

Have you found any mould seams? I can see a "seam" around each "lens", but can't make out whether or not there are mould seams around the rim or bottom?

[Scott13]

 The plasticity of hot glass always amazes me—you should see my Sevres bowl 
Sue I’m usually pretty good at finding mould seams but I haven’t been able to find any on the rim or bottom—I’m not sure what that means ; that it’s been machine made and is relatively modern?
Which I’m beginning to think is probably the case.

I’m not sure this has been moulded or machine made. It looks like it has been blown after the lenses were formed as you can see the pattern goes to the top and is distorted around the neck. It looks like there are tool marks on the bottom.

[Scott13]

  Hi Ekimp
 The lenses do vary a bit in terms of their shapes and sizes.
  And yes the pattern does run into the neck— with the lenses creating the distorted vertical lines up to the rim.
  The lenses are convex on the outside and concave on the inside—I suppose you would get this both on a blown moulded
  piece—and a moulded and then blown one ?
  As my knowledge of glassmaking is pretty superficial I think at this stage I might just be beginning
  to lose the plot 
  The marks on its base could well be fire polished tool marks.

   Interesting take..........thanks for looking
