Glass has been used for various purposes since time immemorial. Glass was first obtained from the cooled volcanic eruption and called Obsidian, was used as a weapon, money and even ornaments. Through the years, production of glass has developed a lot making the process easier, profitable and fast. It was during the late 19th century that glass was manufactured with an automated process.
Glass is made by mixing sand, limestone and soda ash and melting it at the temperature of 3180 degrees Fahrenheit. To improve the durability of the glass, aluminium or titanium must be added at this point. Recycled glass is also added to the mixture and if the client’s requirement is of coloured glass, then the chemical is added to the mixture as well. The mixture is heated for 24 hours for it to form molten glass called ‘gobs’. These gobs are then used to prepare a solid glass of desired shape and size using either of the two methods.

The glass blow method is a traditional method to manufacture the glass. Although it is not as widely used these days, some manufacturers as those of small container jars and container jars wholesale cheap outlets, still use this method to make the glass. In this method, the job is transferred to the moulds called blank or parison. A blow of air is pushed down the blank mould to form the neck of the jar. Another blast of air is applied to the neck causing the liquid to spread towards the wall of the mould. The glass piece formed is then transferred to another mould where the glass is reheated to form the final shape. Compressed air and vacuum is the final step in moulding of the glass.
Another method, which is widely used, is the press and blow method. The gob is transferred to the mould with the help of a plunger. This step helps in giving the shape to the glass. The mechanical arm is used to transfer the partially formed shape into finishing mould, where the blowing is done to attain the desired shape of the container. The finished product is taken out with the help of tongs and placed in the cooling plate. This entire process takes just a few seconds and therefore the final product is still at a very high temperature when it comes out of the mould.

The next step in the press and blow method is annealing. This is done to make sure there is no air bubble or any unwanted insertion in the glass. A long furnace, called Lehr, helps in cooling the glass at varying temperatures but in a controlled way. The process of cooling the glass can take anywhere between 30 minutes and 2 hours. To make sure that the glass is free from any scratches, a layer of coating is applied to it before it enters the Lehr and also after it exits it.
