Vintage Sommerso Art Glass Bowl, Cobalt Blue and Opaline, Lobed Rim, Murano Style, 1960s-70s

A striking hand blown art glass bowl in deep cobalt blue with a pale opaline centre that catches the light beautifully. The lobed rim gives the piece a soft, organic quality, somewhere between a flower and a seashell.
The contrast between the intense cobalt outer glass and the milky pale blue interior is really lovely, shifting depending on the light and angle.
No maker's mark. Attributed as Murano style based on the technique, form, and quality of the glass.
