hello Arka - I'm sure that it's not the case that people lack the interest in helping you, but far more likely that your glass remains as much a mystery to the rest of us as it does to you.
Signatures on glass can be impossible to decipher, sometimes, and as you can imagine the world is full of modern art glass - so unless there is some really positive attributable feature then most of the time pieces like yours frequently remain unknown.
There is possibly a commonly held belief that unusually large and colourful pieces 'must be from Murano' - and yours may indeed be from the Gulf of Venice - but equally your piece might be from the Far East where similar looking glass is made - unfortunately, identification isn't a precise science - and your glass may well remain unknown.
Congratulations by the way on your excellent English
