This antique clear glass bottle was produced by the Schlotterbeck & Foss Company for their line of liquid fruit flavoring extracts, commonly used in baking and food preparation for flavors such as vanilla, lemon, orange, almond, or peppermint. The front panel is embossed with "FOSS' 2 OZ. FL. LIQUID FRUIT FLAVORS PORTLAND, ME." One side features the embossing "STANDARD QUALITY," while similar bottles often have "FULL STRENGTH" on the opposite side (though not clearly visible in the provided images, this is a common configuration). The bottle stands 5 inches tall and measures 1.75 inches wide, with a rectangular shape and a narrow neck designed for a cork stopper (cork not present). The glass is transparent but exhibits signs of age, including internal brownish residue, exterior dirt and minor scratches, and some rust-like specks near the base. The bottom shows a rough mark that may resemble a pontil scar, suggesting possible hand-blown construction, though given the production era, it is more likely a mold seam or manufacturing artifact from early machine processes. This bottle is a classic example of late 19th-century apothecary and food extract packaging, ideal for collectors of antique bottles, Maine memorabilia, or vintage kitchenware. It would display beautifully after gentle cleaning.

Origin: Portland, Maine, United States. Manufactured by Schlotterbeck & Foss Company, which was founded in 1866 as an apothecary and later expanded into producing flavor extracts, syrups, and pharmaceuticals. The company was incorporated in 1892 and operated in Portland for over a century.

Age: Circa 1890s to early 1900s. Based on the embossing style, company history, and similar dated examples, this bottle likely dates to the late 19th century, around the 1890s. Some variants extend into the 1920s-1930s, but the design aligns with earlier production.

Condition: Good antique condition for its age. The glass is intact with one noted chip at the top and what appears to be a small crack right at the opening, but it's smooth on both sides so I think it may be a manufacturing flaw. There is visible dirt, residue inside (possibly remnants of the original contents or accumulated debris), and light surface wear consistent with being dug or stored over time. The embossing is clear and legible.

Material: Clear molded glass, likely produced using early blow-molding techniques common in the era.
