Hand-Blown Art Glass Swirl Cylinder Vase

This item is a cylindrical hand-blown art glass vase or vessel, characterized by a dynamic, organic swirl pattern. The piece is constructed from clear glass with internal veining of olive green and translucent white, creating a marbled or smoky 'calcedonia' style effect. Physically, the object features thick, heavy walls and a weighted base, indicating a high level of craftsmanship and structural integrity typical of mid-to-late 20th-century art glass. The rim is slightly uneven and hand-finished, which is a hallmark of the blowing process. Notable features include the spiral movement of the pigments, which transition from dense bands at the bottom to more ethereal, wispy clouds near the top. Small bubbles, known as 'seeds,' are trapped within the glass, further confirming its hand-crafted nature. There is a visible small white sticker or remnant of a label on the exterior side, though the text is not legible. The condition appears excellent with no visible cracks or significant chips, although there is a slight surface scratch or line visible on the lower left side, which may be a surface scuff or a tool mark from production. The style is reminiscent of Scandinavian or Italian Murano designs from the 1960s-1970s, though it lacks a definitive maker's mark in the view provided. The overall aesthetic is one of modern organic minimalism.
