Do you know what sintered stone is
sintered stone is defined as the process of compacting a solid substance without melting it to the point of liquefaction through heat and pressure. sintered stone occurs naturally in mineral deposits or in the manufacturing process, during which the atoms in the material diffuse through the particles, fuse the particles together and form a national body. Therefore, by definition, porcelain, ceramics and rock slabs are all "sintered" materials. But there are some differences between these products.

Tiles are usually made of very dense clay with a water absorption rate of 0.5% or less. Ceramics are made by firing clay with a water absorption rate greater than 0.5%. Both of these are fired at extreme temperatures in a kiln, generally at 800°C-1200°C.

Ceramic tiles are divided into glazed and unglazed. Glazed tiles are baked twice, giving them durability and luster. Some people call unglazed tiles "full body". However, most tiles used for larger areas have patterns applied to the surface, which gives them more style options, and reduces porosity and increases durability.
