A superb and visually cohesive group of six aqua glass flavoring extract bottles produced by the esteemed Joseph Burnett Company of Boston, one of the earliest and most influential American manufacturers of culinary extracts, notably credited with introducing commercial vanilla extract in the mid-19th century. Each bottle of classic rectangular form with tooled lip and boldly embossed panels reading Burnett’s Standard Flavoring Extracts, several examples retaining the highly desirable “Boston” designation—firmly anchoring the group to its original place of manufacture and distribution.

Dating to the last quarter of the 19th century, these bottles represent a period when Boston stood at the forefront of American commerce and production, supplying goods throughout New England and beyond. Their recovery in Sandwich, Cape Cod—home to one of the earliest and most important glassmaking centers in the United States—creates a compelling and authentic regional narrative, linking manufacture, use, and discard within a distinctly historic New England context.

The condition of the group is exceptional. Each bottle retains bright, clean glass with crisp, legible embossing and no damage, an increasingly scarce state of preservation, particularly among excavated examples. The subtle aqua coloration and uniformity of form lend the set a strong visual presence, ideal for display within a period kitchen, apothecary setting, or curated folk art environment.

A rare and highly appealing New England grouping, distinguished by its Boston origin, Cape Cod provenance, and remarkable state of preservation.
