A glass bottle is a bottle created from glass. Glass bottles can vary in size considerably, but are most commonly found in sizes ranging between about 10ml and 5 litres.
The history of glass can be traced back to at least 12,000 BC where glass coated objects have been found.[1]
Millions of glass bottles are created worldwide every day. In the US, there is an average of at least two bottle-making factories in each county. It is a highly mechanized process, and bottles in use today are no longer hand blown as they were in the past.[citation needed]
A glass bottle is 100% recyclable with many new bottles containing glass which was created over 20 years ago. Less energy is used in recycling a glass bottle than creating the glass from raw materials, helping the environment.[2]
When a glass bottle filled with liquid is dropped or subjected to shock, the water hammer effect may cause hydrodynamic stress, breaking the bottle.[3][4]
Glass bottle manufacturing takes place over several stages. To briefly outline the processes from beginning to end: raw material, melting, forming, annealing, physical inspection, machine & laser inspection, secondary physical inspection, quality control, and finally packing.[5]
Glass bottles are sometimes reinforced through lamination. Laminated safety glass is made by coating a glass surface with a layer of plastic. When a standard glass bottle is dropped, the glass breaks and scatters. When a laminated bottle is dropped, the glass still breaks but the layer of plastic remains intact, keeping the glass pieces together.[1]
Once made, bottles may suffer from internal stresses as a result of unequal, or too rapid cooling. An annealing oven, or 'lehr' is used
