Historical Casting & Provenance

Individually mouth-blown into beechwood molds, yielding faint organic wave striations characteristic of pre-war European glassworks.

Hand-finished in Boston by skilled glassworkers. Subtle variations in bubble distribution, wall thickness, and pontil markings testify to authentic artisan execution.

Glass Composition & Joint Precision

Low-iron borosilicate flint glass (3.5mm wall thickness). 1:10 precision ground joint ensuring an airtight seal without rubber or plastic washers.

Glassware Material: Kiln-annealed soda-lime silica, mineral metal-oxide tinting. Heavy wall density: 3.5mm – 4.2mm.

Studio Care & Maintenance

Wash with warm water and soft bottle brush. Keep the joint clean and dry when storing dry spices, ink pigments, or aromatic salts.

Studio Advice: To prevent ground-glass stopper binding over extended storage, avoid pressing the stopper forcibly when wet. Store in ambient dry room temperatures.
