you might be on to something. If I do try it, I will post some pics. I'm guessing with a broken top it has no real collector value so what could it hurt, right?
What about the clay jug? All I know about it is that Douglass Co. became Gladding & MacBeam.
the air bubbles arent an issue, the problem is you would introduce thermal stresses that would probably break the bottle as it cooled unless it was put in a glass kiln and allowed to cool slowly and evenly. You can do it with certain types of glass like pyrex but not likely that coke.
