The newest documents first part (earliest 20 users) are a compressed type of the three site that make up the latest bottle dating concerns “key” and this starts with the three issues on this page here and you can goes on for the various questions towards the Mouth area-Blown Bottles Relationship webpage or Host-Produced Container Relationship page. So it PDF document is basically the same as – and can be used as opposed to – the newest series of concerns one initiate less than. They, however, are unable to link to various container detailed terminology used in the latest inquiries which have frequent gorgeous hyperlinks checking some other screen identifying otherwise detailing the definition of.
Concern #step one : Does the bottle have raised embossing on the base, body, shoulder, and/or neck Otherwise a distinct vertical side mold seam visible on the body, shoulder, and/or neck (or both features)?
Yes – The bottle has embossing or visible vertical side mold seams somewhere on the body between the heel and the base of the finish or lip. A bottle s but no embossing, but all embossed bottles were molded in some way and have mold seams even if they are not readily apparent. The majority of the bottles made in the 19th and virtually all in the 20th century were made in molds so “YES” is the most likely answer 
to this question. If so, move to Question #dos below. (See note #2 below if there is embossing but it is only within a disk of glass which appears applied to the neck, shoulder or body of the bottle.)
This relationship secret, while the detailed before, is founded on a substance of information of many supplies, since changed and you will/or lengthened for the for the empirical observations of the website copywriter and other experienced anyone who was consulted
No – The bottle has NO embossing and NO apparent vertical side mold seams on the base, body, shoulder, or neck. This bottle is either free-blown, “dip” molded, or was produced in a “turn-mold” (aka “paste-mold”) where the side mold seams were erased during manufacture. A “NO” answer is much less likely than “YES” for this question as a very large majority of bottles made during the 19th century and virtually all made during the 20th century were mold blown resulting in mold seams; see the notes below. If you are sure that the answer is “NO”, move to Question #step 3 below.
Cards: 1. A low probability though possible “NO” alternative is that the user has an unembossed, molded bottle with no visible vertical side mold seams. This can be due to one or a combination of factors including post-molding hot glass “flow” masking the mold seams, fire polishing of the bottle body, or atypically good mold part(s) fitting precision. If necessary, look very closely at the bottle shoulder – the best location to see vertical side seams on mouth-blown and most machine-made bottles – in good light with a hand lens to see if there is at least some faint evidence of where the mold part edges came together. Often the vertical side mold seams are evidenced by very faint changes in glass density in lines where one would expect mold seams to be.
