Opalescent glass bowl with blue and white swirl pattern, likely Kosta Boda 'Atoll' series

This opalescent glass bowl exemplifies Scandinavian mid-century modern design, characterized by organic forms and subtle color transitions. The swirling white and blue pattern was achieved through specialized glassblowing techniques that became popular in Swedish glass factories during the 1960s-1980s. Kosta Boda's 'Atoll' series, designed to evoke underwater coral formations, became one of their signature decorative lines during this period. These pieces appeal to collectors of Scandinavian glass, mid-century modern enthusiasts, and decorative arts aficionados who appreciate the craftsmanship of hand-blown art glass. The organic, nature-inspired aesthetic and the technical skill required to create the opalescent swirl effect make these bowls highly desirable among glass collectors and interior designers seeking authentic vintage Scandinavian pieces.
