Vintage Glass Reagent Bottle with Ground Glass Stopper

This is a vintage clear glass reagent bottle, likely used for chemical storage in a laboratory or as a pharmaceutical bottle. It features a classic cylindrical body with a short, flared neck that tapers to accommodate a ground glass stopper. The stopper itself is a solid, rounded piece designed to create an airtight seal with the bottle's neck, a common feature for preserving the integrity of chemical reagents. The glass appears to be colorless and relatively thick, suggesting durability. There is a prominent black numeral '110' applied as a label on the side of the bottle, possibly indicating an inventory number, volume marking, or internal classification. The overall condition of the bottle shows signs of age and use, with visible residue or cloudiness on the interior and exterior surfaces, indicative of past contents or prolonged storage. There are no immediate visible cracks or significant chips, but the general dullness of the glass suggests a lack of recent cleaning and potential etching from its previous contents. The ground glass stopper ensures a high degree of craftsmanship for its intended purpose of sealing against evaporation or contamination. The design functionality points to a utility item rather than decorative, dating potentially from the early to mid-20th century. The quality is typical for laboratory glassware of that era, focusing on practicality and chemical resistance.
