The given illustration shows the process by which glass containers are being made. Overall, it is evident that the process consists of nine stages beginning with melting glass until the containers are ready to be packed.
Firstly, the glass particles are put into a furnace and heated at 105 celsius before it is pressed into a smaller mould. After the glass has taken shape, it is then transferred to a bigger mould, which has a thick wall surrounding it. Following this, air is pumped into the mould to expand the glass and shape it into a wide container
Lastly, once the containers have been cooled down, they are then made it to the last stage, which is quality control that will be done by the employee. In this last stage, the glass containers are checked by the workers for any defect to ensure that they are suitable for sale and have met the quality standards, which will eventually be packed in boxes to be sold. Meanwhile, the containers that do not passed the quality check will be discarded as waste.
