First this cautionary note: Bottle dating just isn’t a science that is precise! Making use of simply physical, manufacturing associated features that are diagnostic many utilitarian containers can frequently simply be accurately put within a romantic date selection of 10-15 years (i.e., 1870 to 1880 or 1885). There are several cause of this:

1. Like numerous companies making the leap from manual craftsman manufacturing to industrialization and automation, technical improvements in bottle manufacturing weren’t instantly accepted by glass manufacturers or their staff. Recognition frequently happened over a length of several years or years in some instances. This technology lag makes some characteristics that are diagnostic than others for dating. This is noted where understood.

2. As being a corollary to no. 1, look at the following estimate: “Treat terminal times with care. We could usually have some indicator of the date that is starting a strategy whenever we will get whom first place the concept into training. But any strategy, as soon as developed, may be used right up to the current – as much enthusiasts understand who’ve been therefore regrettable as to depend too greatly for a favorite termination date as certain proof of real antiquity. ” (Toulouse 1969b). In a nutshell, there is (and it is) absolutely nothing to stop a glassmaker from having an obsolete technique in the creation of a container.

3. Some technical modifications had been costly rather than used by glass manufacturers until it became an “adapt or perish” problem and numerous cup factories simply perished.

The change to your completely automatic container device from mouth-blown and some semi-automatic techniques into the very early century that is 20th the classic instance (Toulouse 1967, 1969a). (begin to see the Glassmaking & Glassmakers web page)

4. The bottle that is same have now been recycled and reused several times for quite some time before finally being discarded – entire or broken (Busch 1987; see website link below). It was nearly universal with numerous drink container kinds ( e.g., soft drink, alcohol, milk) but ended up being variably normal with almost any type bottle – specially ahead of 1920. Needless to say, soft drink & alcohol containers were reused up to quite recently; milk containers beyond the century that is mid-20th. The bottle pictured to your right has a Wait’s Liver and Kidney Bitters label pasted throughout the embossing of the Star Kidney and Liver Bitters bottle! (the 2 services and products had been from split organizations that have been cross-town Sacramento, CA. Competitors through the belated nineteenth to early twentieth century. The writer in addition has seen celebrity Bitters labels on Wait’s containers in addition to both labels in the immensely period popular Hostetter’s belly Bitters bottles! )

Reuse, needless to say, will not replace the production date associated with container it self, but care must certanly be exercised while using the known date of 1 or several containers up to now other products discovered through the exact same context. Each time a known or likel “older” item can be found in a known “newer” web web web web site it really is called deposition lag. A typical example of this is actually the choosing of some pontil scarred utilitarian containers among otherwise belated 19th or century refuse that is early 20th. It really is not likely that this container had been made through the era that is same but alternatively ended up being reused for a long duration or perhaps retained until broken or discarded. Pontiled base fragments may possibly also be from later on produced “specialty” containers that are described below.

5. Some container forms are indicative of the manufacturing that is particular, though numerous container styles/shapes were utilized for a lot of years

– just like the cylinder whiskey “fifth” or square snuff container – that the design it self just isn’t indicative of age. Other diagnostic tools must be employed to date these things. Shape is more indicative of function, for example., just what the container had been useful for or included, though also that may have an array of exceptions.
