Have a beautiful art glass bowl I need some help with. I am almost certain it is from Murano, but I am trying to nail down the specific maker. I have seen similiar pieces from Barovier & toso. Bowl is cased glass, black with a metallic red/orange. Measures 7 3/4" wide and is 2 3/4" tall. Hoping someone can confirm the maker. Also is there certain keywords i should use if I were to decide to sell this. Thanks in advance.
