I bought this lamp in the far north of Italy
the main cylinder seems to be blown glass with a checkered pattern applied afterwards. glass added first horizontally and then vertically. When I first saw it hanging it looked like it was etched.
10 w x 15 h inches

at a quick glance this decoration has some similarity to the Murano techniques of 'latticino' or possibly filigrana - processes which used white or coloured canes incorporated within the molten glass, which when blown or distorted produced internal threading, throughout the thickness of the piece, but ....
If as you say the white threading here is applied externally then it's not going to be either of the above.
Etching is a wet acid process made after the glass is cold and is the opposite, usually, of relief - in other words acid cuts into the glass to create a pattern of some sort and so is, as the Italians say, 'intaglio'. Assume there wasn't a makers label on this piece?
If you are able to see the thickness of the glass, is the white threading definitely on one side only, and not within the thickness, and assume can be felt on one side only. There are folk here who hopefully will have the answer to your question, but assuming the threading is a surface treatment only then it sounds to be possibly something akin to the C19 decorative process of applied machine threading. but that is my opinion only and I could be a long way from accuracy since I know almost nothing about C20 decorative art glass from northern Italy.
Fingers crossed someone here will be able to help. :)

The vertical stripes look like overshot - ground glass that has been applied while the glass was hot. Your photos are much larger than they need to be as a result the definition of some of them is very poor and detail is lost, the file size is fine but the dimensions are just too large - if the largest size is say 700 pixels (yours are 3200) then that should work much better.

thank you for the replies
I now see that the horizontal white lines are within the glass and the vertical lines applied after (quite likely over-shot as mentioned)
the attached photo is re-sized, maybe the details will be more clear
had I bothered to ask the seller, I am sure he would have claimed it was Murano ;D
this piece looked rather unique (and expensive)

other re-sized photos attached

Much better thank you. Yes looks like overshot, can even see a few stray bits of glass in between the stripes. Would assume the that the line running around the shade is trailed on, depending how much it is worked afterwards a trail can stand proud of the surface or become completely worked in so that you can not feel it. It could also be covered over with another layer of glass.
I have a couple of great lights that I could show, both quite modern, one is definitely from Murano, will try and take some photos later in the week.

quite happy to have found who made the lamp ;D
German designed Bonn pendant by Wilhelm Wagenfeld for Peill & Putzler, 1950s
and it looks great with the lamp on, changes the appearance of an entire room
I would love to see the lamps you mentioned too
