Which type of tile is fired at the highest temperature?

Vitreous tiles are characterized by their ability to absorb minimal water due to their dense, hard composition, which is achieved through the firing process. Among the types of tiles listed, impervious tiles are fired at the highest temperatures. This high firing temperature helps create an exceptionally dense and low-porosity material that does not absorb water, making it suitable for environments subject to moisture, such as bathrooms and kitchens. Impervious tiles exhibit the lowest water absorption rates, typically below 0.5%.

This characteristic ensures their durability and resilience in various applications, highlighting the importance of the firing process and temperature in defining the properties of different tile types. Stronger, denser tiles, such as impervious ones, benefit from this high-temperature firing, allowing them to perform exceptionally well in challenging environments. Thus, when evaluating tile types, the highest temperature firing used for impervious tiles plays a decisive role in their low porosity and overall suitability for specific applications.
