Bologna Bottle - The Creation of Bologna Bottles, or Bologna Vials As They Were More Commonly Known.

The Creation of Bologna Bottles, or Bologna Vials As They Were More Commonly Known.

After learning that Bologna bottles were more commonly called Bologna vials, a little more information came to light.

It must be stressed that the creation process written in the section above is referring to Bologna vials only, as no definition could be found of a Bologna bottle at all. The definitions of Bologna vials varied however, some being of inner fortitude, some of outer, but neither author or definer seemingly aware in any way of the knowledge of each other's work. Although a definition of Bologna vials was in the 1913 copy of Merriam-Websters dictionary, searching today yields little else but sausage. As for "Bologna bottle", that appears to be a rather modern phrase for a flask shaped bottle rapidly cooled on the outside and slow cooled on the inside during the glass-making process. This causes the stresses to be concentrated on the inside of the flask, while the quick cooled, compressed, extremely hard, and otherwise incredibly brittle glass on the outside is held together by those powerful internal stresses. One teachers manual for the instruction on the demonstration and explanation of the Bologna bottle listed the manufacturing process as quick cooling a glass right after being blown, then annealing it from the outside again and as annealing specifies, allowing it to cool down slowly once more.
