Hi All
I have just received the following reply from Ron at Artius Glass - which confirms the views that this weight doesn't belong to any particular range, and is probably a trial piece.
<<Hello Jackie,
Apologies for delay,
Now Very nice weight but not identifiable as part of any range except for it's similarities to the construction of Kyoto. However the orange is a bit of an anomaly.
So I would guess made during the same period as a trial or just an oddity which would have been sold through the shop at the Studio.
No later than 1989/90 though as this was when the triangle sticker was discontinued. To have the many hundreds of colours shapes and designs made over almost 4 decades would have needed a book as big as an Encyclopedia Britannica for images alone so there are limits!
All colours and canes are added to the hot glass and then worked in to the surface hence being able to feel them - some more than others naturally.
Sorry I can't be of further help. Value at around £35 - £40.00 at a guess. A nice little item.>>
Thanks to Ron for his assistance once again.
