Question #step three : Is the bottle cylindrical/round, exhibiting very symmetrical conformation, and with the body and/or neck having faint concentric "rings" or striations on the glass surface going horizontally around the body of the bottle as shown in the picture below?
Note: The turn/paste shape, free-blown, and you may dip molded bottles are also mouth-blown or hand made bottle, that's shielded more about the new Throat-blown bottle relationship page (connect lower than)
The newest concentric groups are not always just like the noticeable since the picture shows (mouse click in order to boost) and sometimes maybe not apparent, regardless if when the present it’s a definitive diagnostic element.
Sure - This bottle was produced in a turn-mold which was also known in the glass industry as a paste-mold. All turn-mold bottles are cylindrical and unless stained, will usually have a polished looking sheen to the glass surface. The large majority of turn-mold bottles date between 1880 and 1915, though they were produced as early as the mid-1850s and as late as the early 1920s (Switzer 1974; Deiss 1981; Jones & Sullivan 1989; Boow 1991; Gerth 2006; empirical observations).
A beneficial "YES" way to so it real question is more likely than just a "Zero". Visit Question #5 to possess a prospective matchmaking refinement according to research by the style of become app, though some of symptomatic enjoys would be disguised from the turn-mold design techniques.

NO - The bottle is either not cylindrical, or if so, is very crudely made and non-symmetrical exhibiting no concentric body/neck rings.
