Hand-blown art glass vase featuring a deep cobalt blue body with vivid lime-green glass inclusions fully embedded within the glass mass. The technique demonstrates hot-worked studio production rather than surface decoration. The vase reflects characteristics of Central European art glass from the 1960s–1970s, a period known for experimental colour work and expressive, non-standardised forms. Comparable examples are associated with Bohemian and neighbouring glassmaking regions, although no definitive attribution is possible. Each piece of this type was individually produced, resulting in subtle variations that underline its handcrafted nature.
