I've had a lot of fun researching this piece, but now I need help to pull it all together.
19cm high x 16cm dia. Fairly chunky, but not overly heavy......my scales are now with my repairman. Pushed in base and partially rough pontil mark. Full of bubbles of varying sizes. Loads of inclusions, and some sort of residue around the rim. Despite the rough appearance, both the inside and outside surfaces are fairly smooth to the touch.
First thought was Hartley Wood, due to the base, but even though some of their pieces are "wonky", none that I found were as roughly made.
Then Biot, which was a fairly good match to the colour but, again, not so much in terms of inclusions/finish, and most of the pieces I found were signed.
Finally got to use the word "Pulegoso" in a search, but the pieces I found appear more opaque. Learnt a bit about Napoleone Martinuzzi…… very wishful thinking...… but I did notice that the handles on this piece aren't even, so lopsided handles does not necessarily mean it's rubbish! Unfortunately, no picture of the base, or side view.

There is no wear visible on the base, but the base is not flat and it only seems to rest on a couple of centimeters each side - it actually rocks. Did the cocoa trick to check where the wear should be (this is also really useful if you are suspicious about wear marks on a piece - just put a thin layer of powder on a flat surface and place the piece on top, press down firmly and when you lift it you can see exactly where the wear marks should be). Photo below. With all the weight on such a small area, I would have expected at least some wear marks.
The other reason I think it is more likely going to be a recycled glass, made yesterday, homage to a roman flattened flask is that there is absolutley no grime around the applied handles, and on one side there is a small hole where the upper part of the bottom of the handle joins the body, and it looks pristine inside.
Lots of photos to try and give as much info as possible.
