Bought today is it Murano? (ash tray)

Sommerso glass - blue outer with red inside -triform 5" across rounded off - flat polished base wirth lots of wear - is it Murano and any idea of age and maker

Thanks Adam

Yup, Murano tourist-ware. Could be from the 1950s onwards...

Probably quite hard to pin down a specific factory, because so many of them produced very similar designs for this end of the market (and often at the high end of the market too!).
