Venini Monofiore Balloton Vases beautifully display the Balloton technique through their unique texture and sparkle. During the glass blowing process, hot glass is pressed into a metal mold that imprints the glass with a crossed relief effect. Each vase is then adorned with a colored glass thread around the lip of the vase. These hand-blown Murano glass vases were first designed in 1970 then brought back to production in 2016.
