Several of the bowls made by Fratelli Toso and Barovier-Toso have the horseshoe shaped under-bowl supports, so it is not a good characteristic for saying something is not Murano. I do not recognize the bowl in this post, so don't know if it is Venetian. It may be, or it may be from one of several other countries (e.g., Czech Republic or Canada). Does anyone recognize it?
