Cobalt Blue and Clear Cased Art Glass Bud Vase

This item is a contemporary cased art glass vase, likely produced in the late 20th or early 21st century. It features a bi-color construction using the 'sommerso' technique, where a core of deep cobalt blue glass is encased within a thick, heavy layer of clear crystal. The vase's form is an elongated ovoid or teardrop shape, characterized by a narrow aperture at the rim and a substantial, weighted clear base that provides stability and a high refractive quality. The transition between the saturated blue interior and the transparent exterior is crisp, indicating skilled glassblowing and controlled heat management. The exterior surface is polished to a high mirror-like finish, though reflective highlights suggest some minor superficial surface scratches may be present. The base appears to be flat-ground and polished, which is a hallmark of quality handmade glass. There are no visible maker's marks or signatures in the provided image, but the style is reminiscent of Scandinavian or Murano studio glass traditions. The piece is in excellent vintage condition with no apparent chips, cracks, or fleabites noted on the visible rim or body.
