The new data files very first area (basic 20 users) was a condensed type of the 3 site that comprise the new container relationships inquiries “key” and this starts with the 3 concerns on this page listed below and you can goes on to the some inquiries on Lips-Blown Container Relationship web page or Machine-Generated Bottles Matchmaking page. It PDF file is actually the same as – and certainly will be studied unlike – the fresh new variety of issues you to initiate below. It, obviously, can not relationship to the many package descriptive words found in new questions which have constant sensuous website links checking other screen identifying otherwise detailing the phrase.

Concern #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.)

So it dating key, given that noted earlier, is based on a chemical of data from of many provide, due to the fact modified and you may/otherwise prolonged for the to your empirical observations of your own webpages creator or other educated anyone just who have been 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 were mold blown resulting in mold seams; see the notes below. If you are sure that the answer is “NO”, move to Matter #step 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.
