Question #1 : Does the bottle have raised embossing on the base, body, shoulder, and/or neck Or 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 Concern #2 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.)
Which dating key, while the listed before, is dependant on a composite of data out-of many present, since the changed and you can/or lengthened towards for the empirical findings of webpages copywriter or any other experienced individuals just who was basically consulted
Zero – 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 https://datingmentor.org/cs/ were mold blown resulting in mold seams; see the notes below. If you are sure that the answer is “NO”, move to Concern #3 below.
Notes: 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.
