Just adding more thoughts and pictures. Carol I took on board your challenge of making a judgement call

and thank you so much for the pictures of the glossy vases example. I think the shape of my green one is very similar to yours although a different size.
Today I bought another of these vases sold as Carlo Moretti unlabelled though.
It is 10" high and has the uncoloured frosted foot. The green is 12" high and has a same coloured foot.
In my humble and inexperienced opinion, looking at them both together, and having now looked at around twenty or so examples in different colours labelled and unlabelled on the net, they are the same maker.
I have however, not managed to find a single example that is 12" tall as my green one is.
Most are 10", 14" and 17/18" on all those I have found.
There is something very different about this satin effect on both these pieces, to all my other pieces including the orange jug which I believe is very good quality.
I bought three vases (different shapes)two of which clearly labelled 'Made in India' so I could compare the satin effect and finish and it is vastly different.
There are some differences between the two 'Moretti' vases but the differences, I think, are minimal. I have seen a number of variations on the shape of the 'bulbous' bit of the vases and these two are slightly different from each other, the green being more onion shaped the blue more round. But then I have seen both represented on labelled pieces on the net.
In DK Judith Miller's 20th Century Glass book, there is a yellow one that may or may not have a same coloured foot (on the website I seem to remember there was also a yellow one but with an uncoloured frosted foot so I'm not sure if the book one is this one or another).
So my judgement call is that they are the same maker and I believe they are Carlo Moretti. But I could be wrong
