1. Formation
Vitrified bricks, also called glass fossils, polished tiles, complete glass fossils. It is made of quartz sand and mud, and then polished with a grinding tool. The surface is as transparent and smooth as a mirror.
2, nature
It is weakly acidic.
3, structural characteristics
(1), the color is bright and soft, there is no obvious color difference.
(2) High-temperature sintering and complete porcelain formation produce various crystals such as mullite, which have stable physical and chemical properties, strong corrosion resistance and stain resistance.
(3) The thickness is relatively thin, the flexural strength is high, the brick body is light, and the building load is reduced.
(4) No harmful elements.
(5) The flexural strength is greater than 45Mpa (the granite flexural strength is about 17-20Mpa).
