'Clutha' is Scottish glass, made by James Couper and sons'
In Cyril Manley's book, example 240 looks to me very similar in every way to this small blue jug.http://tinypic.com/a4lx0o.jpg
[which I do not like as much as mine because of shape and handle]
and the blue looks [ sort of ] similar glass to the small green ones.
I believed that for reasons now forgotten that this type of glass was named 'Clutha' after the river and the bubbles and pattern are supposed to be evocative of water but whatever, Cyril Manley says " I believe that there are only two reasons that it is bought at all" ---because Queen Victoria admired it when she visited the factory and and because the firm employed two first class glass designers---Christopher Dresser and George Walton.
"signed pieces are almost impossible to find"
Now he descibes the jug 240 as ' unusual' but sold to him as blue '' Clutha, long before any interest was shown in this type of glass ware".
Here are the pics of the bases--
I have a large heavy green similar glass vase which is similar in some ways but not quite and the base is different.
That would complicate things too much.
On a more personal note---
I spent 25 years buying glass from car boot sales and fairs because glass appealed to me.
Stuff it, lets be honest, it spoke to me. Glass is just wonderful and very affordable but can be enigmatic and hard to identify.
It is more difficult, if you are/have collected/[ing] because you see something there that you find a connection with, without discrimination, in terms of provenance, rather than collecting xy or z.
This forum is just quite, well, perfect. There is a great balance between those of us fairly ignorant and experts and such generosity and tact that
well, how do you celebrate this ??
