This is a premium vintage mid-century modern mouth-blown glass piece manufactured by the renowned German studio Doria Leuchten (originally DORIA-Werkstätten) during the 1960s to 1970s. Design Aesthetics: The piece features a distinct frosted/satin olivine-grey or smoke-toned glass finish. The upper sphere is meticulously hand-decorated with an elegant, organic vertical wavy line pattern reminiscent of stylized grass, flames, or water ripples. Craftsmanship: True to Doria's legacy, each item was individually hand-blown, meaning minor structural variances make every surviving piece completely unique. Functionality: This component serves as an integrated glass base or shade typically designed to house internal lighting. When activated, the textured translucent glass creates a beautifully diffused, ambient glow. In good vintage condition with some small chips and a mark, all described in the last photos.
