Beautiful shell-shaped bowl in thick black glass enclosing white, pink, and green retorcolo and reticello canes, and gold avventurina decorations. This wonderful piece was designed by Dino Martens for the F.lli Toso glassworks, with which the master created his most surprising glass works, using traditional techniques, but obtaining incredibly original effects through the combination of bold asymmetries and unexpected and irregular chromatic shades.
