One. What material is polished brick?
The professional term for "polished bricks" is "glazed polished bricks," which consist of materials such as sand, stone, soil, and chemical raw materials. These are mixed according to different product ratios to create a polished brick surface that is achieved through grinding the entire brick body.
Two. Are polished tiles the same as full-body tiles?
Polished tiles belong to full-body tiles. So, what are full-body tiles? Full-body tiles refer to tiles with a water absorption rate less than 0.5%, which means fully vitrified tiles. Their water absorption rate is very low. The term "full-body tile" should actually refer to "glazed tile". Due to their very low water absorption rate, they are made by high-temperature firing of quartz sand and clay in a specific ratio. Visually, they appear to be harder and more resistant to abrasion, with high strength.

Porcelain tiles are typically polished using specialized molds to achieve a very smooth and glossy surface. From the exterior, they appear as mirror-like and free from noticeable color variations, with vibrant and soft colors.
Polished bricks are made by directly firing and pressing brick embryos at high temperatures and pressures, followed by grinding and polishing the brick surface. They are also known as glazed polished bricks, full-glazed polished bricks, and vitrified bricks (in a narrow sense, all bricks with a water absorption rate less than 0.5% can be called vitrified bricks).
