Transparent gauge glass, also called transparent Sight Glass, transparent level glass and transparent Level Gauge, is usually made of borosilicate glass and aluminosilicate glass. The glass is manufactured into the strip shape and used in boiler or some instruments for observing the liquid level.
It can be used with all media at service conditions up to 6MPa and temperatures up to 430 degrees centigrade.

Are electric car batteries recyclable?
Electric cars are increasingly becoming a popular choice for eco-conscious drivers, but one of the most common concerns is about the recyclability and lifespan of their batteries. The good news is that electric car batteries **are indeed recyclable**, with some advanced techniques allowing up to 95% of the raw materials to be recovered. Governments around the world are also pushing for EV batteries to be designed with recyclability in mind, making it easier to manage their end-of-life.
Beyond recycling, these batteries can be **reused, repurposed, or upcycled** after they've finished their primary use in your vehicle. This not only reduces waste but also extends the value of the materials used in the battery.
When it comes to durability, many people worry that an EV battery might fail before the car itself does. However, modern EV batteries are built to last—on average, between **15 to 20 years**, or **100,000 to 200,000 miles**. Some manufacturers even offer **8 to 10-year warranties**, ensuring that the battery remains functional for most of the vehicle's lifetime.
While EV batteries will eventually lose some of their capacity over time, the decline is relatively slow—about **2.3% per year** on average. With proper care, such as avoiding full charges and using fast charging sparingly, you can significantly extend the life of your battery.
So, what happens when an EV battery reaches the end of its useful life? It doesn't mean it has to be discarded. In fact, many old EV batteries are still valuable and can be **repurposed for energy storage systems**. For example, used batteries from Nissan Leafs have been found to retain up to **60-70% of their original capacity**, which makes them ideal for stationary energy storage at homes, businesses, or even large-scale grid applications.
In some cases, when a battery is no longer suitable for any practical use, **recycling becomes the best option**. Recycling processes involve shredding the battery, separating its components, and extracting valuable materials like lithium, cobalt, and nickel through methods like pyrometallurgy and hydrometallurgy. These materials can then be reintegrated into the supply chain, reducing the need for new mining and helping to create a more sustainable future.
Regulations are also evolving to ensure that EV battery recycling is both safe and effective. The EU, for instance, has set targets requiring **50% recyclability by weight** by 2025, while the U.S. is developing state-specific policies to manage EV battery disposal responsibly.
Recycling not only helps reduce environmental impact but also supports the **circular economy**—a system where resources are reused and recycled instead of being disposed of. By embracing this model, we can make electric vehicles even more sustainable, from production to end-of-life.
If you're curious about how green electric cars really are, from manufacturing to recycling, there’s a lot more to explore. Understanding the full lifecycle of an EV battery gives us a clearer picture of its environmental impact and highlights the importance of responsible innovation.
