He is listed on additional webpage and therefore build with the every piece of information summarized about key.
The file includes every same color photos located accompanying the questions within these container relationship trick webpages, Moreover it is sold with an easy (I'm hoping) to adhere to and you may submit Worksheet to aid a user
The fresh new documents basic part (first 20 pages) try a compressed variety of the 3 webpages that comprise the fresh bottle relationship concerns "key" and therefore begins with the three issues on this page here and you may continues toward various issues to your Mouth-Blown Bottle Matchmaking webpage otherwise Machine-Produced Bottles Matchmaking web page. This PDF file is basically the same as – and will be taken in the place of – the newest series of issues that start lower than. They, definitely, can not link to the many bottles descriptive terms and conditions found in the new questions having regular sexy website links opening up various other windows determining or outlining the expression.
Matter #step one : 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 Question #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 relationship key, since noted prior to, is based on a compound of information out of of several supply, as changed and you can/or offered with the toward empirical observations of site blogger and other educated someone which was basically 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 Concern #step three 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 enkele apps dating mold seams to be.
