About this objectGlass Bottles C.1905-1920
These bottles are an example of early machine blown glass c. 1905 – 1920.
The “V-shaped bubbles in the glass (the narrow end of the “V” points toward the bottle finish) seem to be found only in machine-made bottles and while it is unknown exactly what causes this shape of bubble, it is presumed that it is the result of much higher pressures that a machine can exert over a man's lungs. It is common for an early 20th century machine-made bottle to have a couple of the inverted "V" bubbles, with the rest being normal round or oval shaped as seen in these examples.
