This article focuses on the question of "Are there plastics that can conduct electricity?" It introduces the conductive principles of conductors and insulators, explains the preparation principles of two types of conductive plastics: structural and composite types, and introduces the current application status and development prospects of conductive plastics.

This article focuses on the question of "Can plastic be used to build houses?" and introduces the multiple performance advantages of plastic products compared to traditional building materials. It shows that the current use of plastic in house construction is increasing year by year, and it can be applied in many fields such as pipe materials, wall materials, flooring materials, and furniture installations. At the same time, it points out that the application of plastic in architecture needs to comprehensively consider various factors such as economic cost, environmental protection, and people's living habits.

This article focuses on why some plastics are hard, some are soft, and some are like sponges full of small holes. It explains the reasons for the differences in plastic properties, namely that different molecular structures can be divided into two types of plastics: thermoplastic and thermosetting, each with distinct characteristics. Even the same type of plastic can exhibit significant performance differences due to different processing methods or additives.

This article focuses on the question "Can ceramics be as transparent as glass?" and introduces the production, characteristics, and applications of alumina ceramics, which are transparent like glass and have higher hardness and better high-temperature resistance. It also mentions the preparation methods and application fields of various new high-performance ceramics that are hard and resistant to impact.

This article focuses on the question of "Are ceramics and glass the same?" It introduces that traditional ceramics and glass are both silicate products and share many common characteristics. At the same time, it elaborates on the differences between the two in terms of appearance, raw materials, chemical composition, production processes, and material structures. It also explains the differences between pottery and porcelain and the related knowledge of glass production.

This article discusses why we should promote glass recycling. It points out that ordinary glass has stable chemical properties and is extremely difficult to decompose naturally, which easily leads to long-term waste accumulation. Moreover, the refining of glass consumes a large amount of raw materials and energy. Recycling waste glass can not only reduce the amount of glass waste, but also save energy.

This article focuses on the question of "Is plexiglass a type of glass?" and compares the composition and characteristics of plexiglass with those of ordinary glass, highlighting their similarities and differences. It also introduces the practical applications and drawbacks of plexiglass.

This article focuses on the question of "how are the patterns on glass 'carved' out?" It explains that due to the hardness and fragility of glass at room temperature, it cannot be directly engraved with metal tools. Instead, patterns are created using methods such as rolling, polishing, and chemical etching. The article also details the technological principles of these three methods and the corresponding types of glass products.

This article focuses on the question of why color-changing glasses change color. It introduces the principle that color-changing glasses achieve color changes by adding silver halides (silver bromide or silver chloride) and trace amounts of copper oxide to the color-changing glass. Under different intensities of ultraviolet radiation, the silver halides undergo decomposition or chemical reactions, thereby causing the lens color to change.

This article focuses on the question of "what substance is coated on the back of a glass mirror?" It introduces the development history of mirrors from ancient water surfaces and bronze mirrors to modern glass mirrors, and details the evolution of the coating technology on the back of glass mirrors from early mercury plating (the cinnabar method) to later silver plating using the silver mirror reaction, and finally to the current use of vacuum coating technology to plate aluminum. At the same time, it explains the key points of silver mirror manufacturing and the cognitive misconceptions that mirrors containing mercury can be toxic.

This article focuses on the question of "Is fiberglass made of glass or steel?" and introduces the manufacturing principle, structural composition, performance advantages, and application scenarios of fiberglass. It explains that its scientific name is glass-reinforced plastic, which is an excellent composite material with glass fiber as the skeleton and resin as the flesh.

This article takes "What is a glass curtain wall made of?" as the theme, and introduces the origin and concept of glass curtain walls, the first practical case and early problems, the improvement measures of the production process, the application advantages and current popularity, as well as its existing shortcomings and related usage regulations
