Glass is one of many technologies that helps human throughout the times into the digital era. From lightbulbs to Hubble Space Telescope lens, the glass plays an important role in mankind history. Nobody really knows who invents it first. But traditional glassmaking process is a knowledge that has been widely spread nowadays.
The basic ingredient of glass is silica, a silicon based sand. After preparing the material, the next step would be heating it in the furnace until it turns liquid. You should note that because of its high melting point, melting silica would be a fuel consuming activity. Adding a proportional catalyst soda would be a solution in order to make it easier to melt. After the molten silica has formed, it will be distributed along a metal pipe to separate places, depending on what kind of glass you want to create.
If glass plate is the model that you want to create, then it would be transported into a pressing machine. This machine would convert its shape into a flat-shaped glass. On the other hand, if you want to create a glass bottle, then you’ll need a slightly more complicated steps. The molten silica is poured into a mould that has been designed depends on the shape of the bottle that we want, then you carefully blow air into the mould. And after a few moments, the bottle is ready to be filled with your favourite drinks.
