certainly looks to be a very good match in terms of shape etc., and would agree that the word sensual probably not really applicable here. You may be correct with 'freeform' Anne, but I'd always imagined that word being used to describe shapes lacking recognizable geometric outline - something akin to free-formed dishes - the most well known being Per Lutken's designs for Holmegaard. If you want sensual you should look at some of the Galle, Loetz or Daum work from the nouveau period, as you will of course know well - although that's not to say that the designs being discussed here aren't physically pleasing or gratifying to the senses - just maybe not quite what most folk think of as sensual.
It's a very good question as to who might have been the first to produce controlled bubbled glass, and aside from the outside chance it may have been the Romans, my thoughts are maybe Murano or one of the Scandinavian houses perhaps. It could be an interesting thread to run here - perhaps other people will offer their thoughts on the subject.
However, your comment that "this was already done much earlier by other artists.", suggests that you are one step ahead of us, and probably already know the answer

P.S. sorry to hear of your unstable adventure - what was it - those six inch heels again.
