thanks everyone for such an erudite input. I have no knowledge of this factory whatsoever, so cannot contribute anything academic. Having said that - and having held the piece of course, I can say that it does have a substantial weight and 'feel' to it (tips the scales at 1.6 kilos, and is 19 x 15 cms. in size) - reminds me very much of some of the heavy abstract shaped Czech vases from the fifties and sixties. Get the feeling also that the ground and polished flat base (not really too evident in the pics., I'm afraid) indicates a non cheap piece of glass - and as mentioned, the scratches to the base are what you might see on 30 - 50 year old glass. Given that sort of age, wud there have been any mileage in creating a forged sig. back then? I appreciate that the water staining doesn't necessarily mean a great deal, but am I right in thinking the level of stain we can see might also indicate some reasonable age?? As for the sig., it looks confident in the sense that it has been applied 'smoothly' - without wobbling or going slowly. Hesitant sigs. can be an indication of fraud. Later today I will try to take a better pic. of the sig. - I found it very difficult the first time - again I think the camera has a problem with focusing at the surface level of clear glass - and it is a curved part of the vase of course. Sorry also about the pics. showing pink, it really is just completely clear. Thanks again and as it only cost me a quid, and can actually be used for flowers, I am quite happy whatever it may be (but really wud have liked it to be Daum!) cheers Paul S.
