Picked up this bottle in a box lot and am curious about the mold lines...There is a horizontal line below the shoulder, and then two vertical mold lines from there to the applied top...obviously a three part mold, but no mold lines from the shoulder down...just need someone to explain this bottle to me...I'll try to attach the pic's...Thanks in advance..!!

I am not certain my terms will coincide with others but the bottle was blown in some form of one piece mold similar to or including a hole in the ground with a two piece mold from shoulder up. When ready, the upper mold was opened and the completed bottle was lifted out and the blow pipe removed from the neck and completed by applying or tooling the collar. That's the simplified version but pretty accurate I believe. Jim

Thanks Jim...Here is a pic of the bottom...so, any guess on age of the bottle..??..

1880s to perhaps as late as 1910 or so. If British it could be even a little later. I doubt it's as early as 1870s. Jim

I need to point out here that the dip mold part of these set=ups are made as a casting that can have the cast cavity chilled by a solid core of iron - which when done - creates a glass contact area that has dendritic iron metal in the glass contact area. Dendritic iron has a slower heat transfer speed whch lets the glass blow with even wall thickness. So it isn't whittle - but us cold mold-ripple of thickness structure. RED Matthews
