What is a characteristic of glazed brick?

A glazed brick is characterized by its bright, smooth, glossy finish on one side, which is achieved by applying a glass-like coating during the firing process. This finish not only enhances the aesthetic appeal of the brick, making it suitable for various architectural applications, but also contributes to its durability and resistance to moisture and stains. The glazed surface is often easy to clean, making it a popular choice for both interior and exterior uses. This attribute distinguishes it from regular bricks, which typically have a more matte and uneven texture.

Other characteristics mentioned in the options do not align with the defining features of glazed bricks; for instance, glazed bricks are not rough, nor are they lightweight and easily breakable. They also serve more than just decorative purposes; their functional benefits in terms of durability and maintenance make them viable for a variety of applications.
