Vintage turquoise blue bubble glass coupe

Vintage turquoise blue bubble glass bowl, probably from the 1960s-1970s. Original shape, with a rounded body that slightly narrows before a widely flared opening. The thick glass is mass-tinted in a bright turquoise blue. Numerous bubbles of varying sizes are trapped in the glass, from the finest to a few much larger inclusions. No brand or provenance indicated. In beautiful vintage condition, with some usage scratches on the bottom, visible in the photographs. There is a defect of a bubble that is recessed inside when touched (see photos). Diameter at the opening is 18 cm, height 11 cm, weight approximately 800 grams. A very seventies silhouette and a turquoise that catches the light.
