Murano Style Art Glass Firestorm Corkscrew 18" Centerpiece, a mouth-blown Murano Style Art Glass work of art set on a clear optical crystal base. What a perfect home decor accent to liven up any room and make great conversation. It has some greens, blues, purples and pinks blended beautifully together into a soothing lush design! Art glass is a blend of many colors of glass and it is completely normal to have air bubbles appear in the glass. Colors may also vary from piece to piece making each one a unique work of art.
