One of the fun things about research and identity is that "categories" of glass cross various boundaries. In this case, "Murano Glass" and "Paperweights". Occasionally something like this bowl is a joy to see since it immediately suggests other questions, such as ...
If items like the bowl shown are Seguso (and I am not saying anything to contradict this, as I really have no idea myself) does anyone here know for sure if Seguso pulled their own canes? If they did not, then how is the Seguso attribution confirmed - other than by the trusted reputation of the person making that Id?
If the canes are known to be Seguso, then they become very useful for identifying (and perhaps also dating?) paperweights. In which case, any examples like this would be useful to cross-post to the Paperweight forum for information.
If Seguso did not make the canes then we are left with the usual problem of who supplied them.
