Antique sun-colored amethyst glass bottle marked “ONE QT.” and embossed with a “B” on the base, indicating manufacture by Brockway Glass Company, one of the earliest American glassworks to adopt full machine-made bottle production.
This bottle was found in an attic in Church Point, Louisiana, and has turned a light lavender-purple hue due to long-term sun exposure — a natural reaction in glass containing manganese dioxide, used to clarify glass before World War I.
It also glows under UV light, confirming the manganese content, and features a fully machine-made seam that runs through the lip, placing its likely manufacture between 1912–1916.
Bottles like this were commonly used for vinegar, whiskey, extracts, or pharmacy purposes and are now highly sought after by collectors of:
SCA (Sun-Colored Amethyst) glass
UV-reactive antique glass
Pre-WWI American bottles
Louisiana estate finds
