I would be very comfortable attributing the bowl to Fratelli Toso, based on similar pieces I've owned and extensive photos in the Pina Italian Glass book. F.T. did a lot of bowls in this general shape and style, some more artistically successful than others. They're a lot of fun, and are relatively affordable. The vase is interesting. I've been trying to positively attribute a "alabastro/opalino" sculpture (posted previously on this board), and Archimede Seguso did the most in this technique than others by far. I don't know that others have been working extensively in this technique in recent years/decades, but I could be dead wrong about that. The form doesn't ring a bell as A.S., but I'm a relative neophyte and am still waiting for the Rosa Barovier Mentas book from Amazon -- they take forever to ship items they don't stock.
