glass bottle making is a multi-step process that involves several different stages. below are the general steps of glass bottle making:
batch preparation: the raw materials such as sand, soda ash, limestone, and other additives are mixed together and melted in a furnace.
glass melting: the mixture is heated to a temperature of around 1500°c until it becomes molten glass.
glass conditioning: the molten glass is then refined and homogenized by adding other chemicals to improve its properties.
forming: the glass is then formed into a bottle shape using one of two methods: blow-and-blow or press-and-blow. both methods involve blowing air into the molten glass to shape it into a bottle.
annealing: once the bottle shape is complete, it is cooled down gradually in an annealing oven to relieve internal stresses and strengthen the bottle.
quality control: bottles are inspected for any defects or imperfections before being sent for filling and distribution.
it’s important to note that glass bottle making is a complex and energy-intensive process that requires skilled workers, specialized equipment, and careful quality control measures.
