One of the most captivating parts of the video is the demonstration of the float process itself, which was invented by Sir Alastair Pilkington in the 1950s. After the molten glass is produced, it is carefully poured onto a bed of molten tin. This innovative technique is what gives float glass its name. The glass floats on the tin, allowing it to spread evenly and create a perfect flat surface. This method is a game-changer, as it eliminates the need for subsequent grinding and polishing, which were the traditional methods used to achieve a smooth finish.

But glass is an interesting material, in part because the word itself is a general term, referring not to a substance with a specific chemical ratio, but to a substance with specific structural characteristics that can be made from endless formulations. However, when we talk about glass, we understand it as something very specific: it is a material that is hard and brittle, but with enough heat it can become viscous and fluid. Sometimes glass is mistakenly thought of as a liquid because it will creep (albeit very slowly) even in its cooled state. Glass is not like a solid like a rock because its molecules are not as well organized as any crystal. Diamonds have a very regular crystal structure, as do ice and crystallized honey, but glass does not. Although glass is more solid and reliable than ice, at the molecular level, the arrangement of glass molecules is much less ordered.
