This piece reminds one of a certain other major glass maker DUNCAN GLASS ! But I do not believe it is from there...so for now --it's maker is unidentified ! This bowl is very well made. It features first a offset of the two main bowls.Where they are offset --this opening begins the placement of the largest clear glass bead.This bead is about dime sized. Each bead after that is graduated down to the most tiniest of them...
