Title: Big Somersso Red Cylinder Vase Red/Clear
Post by: LEGSY on May 18, 2021, 03:18:08 PM: Got a nice piece of glass today it is a big piece with good weight lots of wear to the outside of the
pontil scar also, When i took the base picture i got some yellow colors coming out in the pictures not
to sure why this happened but maybe from glare? The vase measures nearly 10" x 5" wide and heavy.
Would love to know any ideas on where it might be made? Thank you

Post by: flying free on May 18, 2021, 11:18:00 PM: is this not just a red vase cased in clear? I thought it was normal for red glass to be cased in clear as otherwise the red appears too dark and/or it's too expensive to use as an uncased colour?
And is this what is known as 'sommerso'?

I have some Stevens and Williams glass from c.1930s that has this curious yellow orangey colour to the clear, not obvious until you start looking closely at an angle.

I have 3 pieces of gold ruby cased in clear lead glass that shows this effect in a very obvious and quite striking manner.This curious effect as been a mild obsession of mine lately. I will post some photos in a separate thread.

Under UV light it fluoresces faintly green, especially in the thicker parts of the glass. As your photo was on a window sill the UV in natural sunlight might have caused the same effect.

Post by: NevB on May 22, 2021, 04:49:36 PM: cagney, I should have made it clear I was referring to LEGSY's vase which was pictured on a window sill in natural light. I think the colour in your pieces comes from something else.
