The concentric groups commonly always since the apparent once the image shows (mouse click in order to enlarge) and often maybe not visible, whether or not in the event the introduce it is a conclusive diagnostic feature.
Yes – 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).
An effective „YES” way to so it question is likely to be than just a good „No”. See Question #5 having a possible dating subtlety in accordance with the sort of finish software, even though some of your symptomatic keeps can be disguised because of the turn-mildew and mold design procedure.

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