Hand-Blown Aquamarine Glass Flask

This is a substantial hand-blown glass flask or decorative vase, measuring approximately 8 inches in height, 6 inches in width, and 3 inches in depth. Crafted from a thick, heavy glass with a distinct light green or aquamarine tint, the vessel features a broad, flattened body with slightly concave sides and a robust, thick-walled neck. The mouth of the flask is finished with a wide, flared, and fire-polished rim. The glass contains numerous internal bubbles, known as seeds, and characteristic waves or 'reams,' which are definitive indicators of a hand-blown artisanal process. The base appears to be thick and slightly indented, typical of mold-blown or free-blown glass of this style. Its construction suggests a 20th-century origins, likely taking inspiration from historical canteen-style or colonial glass flasks. The condition appears excellent with no visible cracks, large chips, or significant clouding, though there is a subtle internal residue or light 'sickness' near the neck area, which is common in older utilitarian glass. The heavy weight and crude beauty of the glass suggest it may be of Mexican or European studio craft origin, emphasizing rustic aesthetic over refined crystal manufacturing.

Upon examination of this hand-blown aquamarine glass flask, I have identified several characteristics consistent with mid-to-late 20th-century artisan production, likely originating from a studio in Mexico or a boutique European workshop. The vessel exhibits 'seeds' (bubbles) and 'reams' (flow lines) that authenticate it as a hand-crafted piece rather than a machine-pressed imitation. The fire-polished rim and substantial weight suggest a rustic, utilitarian aesthetic popular in the decorative arts market of the 1970s and 80s. The condition is generally excellent; however, the minor internal residue or light 'sickness' noted near the neck is a common aging feature that slightly tempers the value. Current market demand for non-attributed studio glass of this size and color remains steady but modest, primarily driven by interior design utility rather than high-end collector scarcity. Comparables for similar un-signed Mexican glass vessels typically fall within this range at estate auctions and vintage retail venues. Please be advised that visual inspection alone cannot confirm a specific manufacturer or chemist's composition for the glass. A definitive authentication would require a physical examination to check for a ground-down pontil mark or acid-etched signature on the base, as well as provenance documentation to link it to a specific artist or studio. Without a signature or direct lineage to a known designer like Blenko or Nason, the value is based primarily on its decorative merit.
