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 www.datingmentor.org/geek2geek-review 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 Matter #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.)

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.
