Hand-blown amber glass tumbler with applied spike decoration

This piece represents mid-century modern brutalist glassware, popular from the 1960s through the 1970s. The applied spike or 'sea urchin' technique was a hallmark of European art glass studios, particularly in Czechoslovakia and Scandinavia, where artisans created decorative yet functional pieces that emphasized organic, sculptural forms. These brutalist glass objects became fashionable during the MCM era as statement pieces that combined artistic expression with everyday utility. Brutalist glass pieces like this appeal strongly to mid-century modern collectors, interior designers, and vintage glassware enthusiasts who appreciate the bold, tactile aesthetic and handcrafted quality. The warm amber color and dramatic spiked texture make these pieces highly desirable for creating atmospheric table settings and adding sculptural interest to contemporary or retro-styled interiors.
