In this How it's made video we will learn how glass bottles are manufactured.
Did you know that glass consumes less energy to produce then metal and plastic and that glass can be endlessly recycled. The glass used to manufacture glass bottles consists mainly of silica sand, soda ash and limestone.
I must say that the glass bottle factory looks very much low tech compared to many of the factories we have seen in the other How it's made videos. If you want to know more about glass and it's history see this wikipedia article.
