The scheme below demonstrates the way of forming containers out of glass.
In summary, this quite complicated process includes 8 steps, starting from melting glass grains and finishing by sending the finished product or wasting it.
To commence with the glass grains, they are melted in a high temperature of 105 °C. Afterwards, the melted liquid, so-called “hot glass” is poured into the first mould before being pressed in order to form the needed shape. The next stages involve another mould which is bigger and has thicker walls. The gotten shape is put in that mould and then is filled with the flow of air.
According to the chart, the produced by this method forms are heated in a kiln by a really high temperature of 482°C. Then, they are cooled in a cooler with the temperature of 25 °C. Finally, the provided layout informs that the cooled containers are being thouroughly checked for defects.
