Glass bottles
Glass bottlesare bottles created from glass. The can vary in size considerably, but are most commonly found in sizes ranging between about 10ml and 5 litters. There are all kinds of glass bottles includingglass beverage bottles, glass milk bottles, glass jam jars and so on.
The history of glass can be traced back to at least 12,000BC where glass coated objects have been found.
Millions of glass bottles are created worldwide every day. On average there are lots ofglass bottle manufacturers in each country. It is a highly mechanized process, and the bottles in use now are no longer hand blown as they were in the past.
When glass bottles of liquid are dropped or subjected to shock, the water hammer effect may cause hydrodynamic glass breakage.
Glass bottles 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, physical inspection(second time), quality control, and finally packing.
To strengthen glass bottles, the process of lamination is sometime done. Laminated safety glass is made by combining a layer of plastic over glass. When a non-laminated bottle is dropped, the glass breaks sending pieces of glass everywhere. When a laminated bottle is dropped, the glass still breaks, though the outer layer of plastic contains the broken pieces of glass.
