Hi cowseatmaize; I think that he took that bottle off the conveyor and sat it on the floor. This was a common practice with machine made bottles. They did this to see if the stresses in the glass, were not too excessive to survive after annealing. It would tell the machine operator if he needed to change the temperature of the glass being lifted out of the molten forehearth. The same practice was done on almost all ABM products. RED Matthews.
To kwalker; Regarding that short showing of the mouth blown beer bottle - take notice of the burst off of the blowpipe. The blower then broke that partial bubble of glass off his blowpipe ready for the next use.

Hi Red, I was referring to a point on the Utube documentary link at about half way. If you look closely there is a small segment where a hand blower puts a gob in a mold and twists it off. The assistant takes it out and it looks like he puts it in a tub filled with water and steam comes out. The blower cleans the pipe off in the same tub.
It's only about 10 seconds of the video.
The quality control monkey-child looked at the bottle and saw it was junk (one all of us would like to have).
Looks like he chucked it in the water vat to break it up. They likely used all that scrap glass as flux to melt down thier next batch of sand.
Just my guess...
