      That’s just a number based on experience. Some bottles break first time out of the factory… others last 15 times. They are used untill they are too degraded for reuse.

        Ah, so this was about melting the bottle down and making a new bottle 7 times? As opposed to washing the bottle and reusing it as it was. Makes much more sense now. :)
