After writing that last message, I checked my Italian Glass book by Leslie Pina. There are some vases that are made by Carlo Moretti on page 48. Some of these vases are glossy and do not have a pedestal base. A couple of the styles have a slightly flared lip, as yours does. Perhaps you can check vases made by Carlo Moretti to see if you can find one that has the same characteristics and dimensions. I would say there is a good chance your vase was made by them.
