Sorry to be a pain, but could we see an image with the light reflecting off the surface, rather then coming through it?
The pattern in the glass reminds me very much of the one produced by Isle of Wight Studio Glass and was one of the designs given to start Kerry Glass off. The colourways were called Peat, Shamrock and Heather, this would be Heather, I think, IF this is what it is. I'm not completely sure about the shape, and the pontil scar would be an unusual feature. Normally, it would have been finished off with a blob of glass put over the scar and impressed with the flame logo.
