)Reuse, of course, does not change the manufacturing date of the bottle itself, but care must be exercised when using the known date of one or a few bottles to date other items found from the same context.

Please be aware that in order to gain the maximum information about any particular bottle (e.g., dating, typing) the user must usually must review a number of pages within this website.

Unfortunately, the complexities of precisely dating bottles is beyond the scope of any simple key.

Utilitarian items include canning/fruit jars and figured flasks since they were intended to be reused by the purchaser and have been observed to follow well the dating guidelines, though there are some manufacturing timeframe differences with canning jars.

(Click canning jar to view the typology page section devoted to that category.) The beer bottle pictured to the above left is a classic example of a utilitarian bottle from the late 19th century that was typically reused.

The shift to the fully automated bottle machine from mouth-blown and some semi-automatic methods in the early 20th century is the classic example (Toulouse 1967, 1969a). The same bottle could have been recycled and reused many times for many years before finally being discarded - entire or broken (Busch 1987).

This was almost universal with many beverage bottle types (e.g., soda, beer, milk) but was variably common with just about any type bottle - especially prior to 1920.

The information on this website will, however, usually produce a reliable manufacturing date range for a majority of American utilitarian bottles manufactured from the early 1800s to the mid-20th century.

Using physical, manufacturing related diagnostic features, most utilitarian bottles can usually only be accurately placed within a date range of 10-15 years (i.e., 1870-1880 or 1885) . Like many industries making the leap from manual craftsman production to industrialization and automation, technological advances in bottle manufacturing were not immediately accepted by glass manufacturers or their workers.

All this adds to the fascination with bottle making, but makes systematic dating similar to solving Rubik's cube - ostensibly simple on the surface but complex in practice.

To misquote an old saying as rephrased by the BLM supervisor that facilitated the initiation of this website project: "The universe (of bottles) isn't just more complicated than you think, it's more complicated than you CAN think." True to a large degree, though much information can be teased out of most bottles with a systematic approach to the matter. This Bottle Dating page (and website in general) is designed to address what the website author refers to as "utilitarian" bottles & jars (click for more information).

A substantial amount of bottle type specific information must be reviewed by a user to increase the probability of dating accuracy.
