This bottle is an amber colored bottle manufactured using a 2-piece with cup mould and has a prescription finish. The seams on the sides of the bottle are indicative of this kind of mould. Embossed onto the bottle is the name “The Oakland Chemical Company” with a chemical symbol in the middle. The bottle likely contained what was known as dioxygen or previously, Oakland hydrogen peroxide. The hydrogen peroxide was marketed as being safe for oral consumption, although today we know it should not be consumed and likely would have burned the throats of people who drank it.
The date of manufacture for this style of bottle (2 piece with cup) is between the 1880s and 1930s, but knowing the company who sold product in the bottle, the date can be further refined to the late 1890s, early 1900s. The headquarters of the Oakland Chemical Company was in the New York City region, moving from Brooklyn to Manhattan and Staten Island. This product most likely would have been found in a household along with other medicines intended to treat ailments.
