Vintage cobalt blue pressed glass bottle made from solid blue glass, not painted or flashed. The bottle features a geometric diamond/lattice pattern with paneled sides and a hexagonal base. Constructed in a two-part mold with visible mold seam lines extending through the body and base.
The underside shows a molded base with a central glass push-up covered by an additional pooled glass gather/blob during manufacture. This is a molded pressed-glass production feature rather than a cut or polished pontil. The bottle has a flared collar neck and heavy glass construction.
Likely produced as a decorative bottle or vase in a Victorian-inspired style. Displays beautifully with strong cobalt coloration and textured light refraction.
Condition shows age-related wear, interior residue/mineral spotting, and surface scuffs consistent with vintage glass.
