Ep 5. Glass

Modern Marvels is an incredibly interesting series that takes a deep dive into the engineering and technological advancements that have transformed the world we live in. Season 8's episode 5, titled "Glass," is no exception. In this episode, we explore the history of glass, its many uses, and how it's made, along with the science behind its unique properties.

The episode begins by taking a look at the earliest known use of glass, which dates back to around 4000 BC in Mesopotamia. From there, we see how ancient Egyptians and Romans improved upon the process of making glass, using it for decoration, jewelry, and even windows in their homes. The episode then delves into how glassmaking techniques have evolved over time, from artisanal methods to mass production techniques.

One of the most interesting parts of the episode is when we learn about the science behind the unique properties of glass. Unlike other materials, glass has no crystalline structure, which gives it its unique transparency and fragility. We also learn how the addition of certain chemicals can alter the properties of glass, making it more resistant to heat, shatterproof, and even bulletproof.

Another fascinating aspect of the episode is the many uses of glass in modern society. From skyscrapers to smartphones, glass is an integral part of our daily lives. We see how advancements in manufacturing technology have allowed for the creation of innovative glass products such as Gorilla Glass, which is used in many mobile devices, and bulletproof glass, which is used in many high-security applications.

The episode also highlights the environmental impact of glass production, including the amount of energy required to melt sand into glass and the waste generated during the production process. We see how some glass manufacturers have implemented sustainable practices to reduce their carbon footprint, such as using recycled glass and implementing more efficient manufacturing techniques.

Overall, "Glass" is an informative and engaging episode of Modern Marvels that explores the history, science, and uses of this essential material. Whether you're a glass enthusiast or simply curious about the technological innovations that have shaped the world around us, this episode is definitely worth watching.
