For centuries, incandescent glass has been etched with a spiked mold to embroider its surface with small reliefs, before being mouth-blown. These intentionally thick glasses gracefully re-actualize the simplicity and functionality of the "goto", the traditional venetian tumbler. Tumblers available in six color variations, made of mass-colored glass, mouth-blown, and worked "a mano volante” (literally “flying hand"): this technique indicates the ability of the glass master's continuous hand movement during the shaping and is exemplary of his talent. Dishwasher safe at 60° C. Weight and dimensions may slightly vary from item to item due to the special “free hand” manufacturing.
