Historical Casting & Provenance

Crafted from hand-gathered cobalt silicate glass containing 2% pure cobalt oxide. The six polished body facets capture ambient light, replicating the grandeur of early 20th-century artisan display windows.

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

High-index optical cobalt glass (4.2mm wall thickness). Hand-cut octagonal faceted stopper with satin-ground seating taper.

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

Studio Care & Maintenance

Clean with a soft microfiber cloth. Avoid abrasive detergents to maintain the crystal-clear polish of the exterior facets.

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

Fragile Freight & Despatch

Packed in archival black tissue inside a stamped Delivery Research Heritage gift box with ribbon pull.
