1. Formation
Vitrified bricks, also known as glass fossils or polished tiles, are created using a combination of quartz sand and clay. These materials are then finely ground and polished to produce a surface that is as clear and smooth as a mirror. This unique manufacturing process gives the material a glass-like appearance, making it both aesthetically pleasing and highly durable.
2. Nature
Vitrified bricks have a slightly acidic composition, which contributes to their chemical stability and resistance to environmental wear and tear.
3. Structural Characteristics
(1) The color of these bricks is vibrant and soft, with no noticeable variations in hue, offering a uniform and elegant look.
(2) Through high-temperature sintering, the material achieves full vitrification, forming crystals like mullite. This results in excellent physical and chemical properties, including strong resistance to corrosion, staining, and weathering.
(3) The thin structure of the brick enhances its flexural strength, making it lightweight and reducing the overall load on buildings while maintaining structural integrity.
(4) Vitrified bricks are free from harmful substances, making them safe for use in both residential and commercial environments.
(5) With a flexural strength exceeding 45 MPa—significantly higher than that of granite (which typically ranges between 17–20 MPa)—these bricks offer superior durability and performance.
