1, first look at the price. Generally, Guangdong bricks (Foshan, the main producing area) are more expensive than Shandong bricks by more than one level. Most high-grade tiles are produced in Guangdong, but the quality is naturally better. Shandong bricks are passable, but the quality is not so bad, but the affordable price is obvious.

2. See if there is a registered trademark of the product on the back of the floor tile. If there is the same logo as the registered trademark of the product, it is Guangdong ceramic tile. If the back is made in China, it is Shandong tile.

3. If the same brand of tiles can't be produced in Guangdong or Shandong, it can be judged as follows: Look at the back of the tiles, if the color on the back is darker, it is made in Shandong, and the price will not be too high; On the other hand, if the back color is lighter, it means that the quality of tiles is better, and of course the price will be higher.

Extended data:

1, tiles produced in Guangdong are generally larger than those produced in Jiajiang, because of the tonnage of the press. Therefore, in terms of brick density, Guangdong brick has a higher density. On the surface, the glaze of Guangdong brick is thinner than Jiajiang brick.

2. The weight marked on the Guangdong brick packing box is generally light, because the railway transportation management in Guangdong is not very strict, and the weight is measured according to the weight marked on the packing box. Jiajiang, on the other hand, all loaded vehicles must be weighed before and after loading. So the actual weight is on the box of Jiajiang brick.

3. Feel it with the back of your hand (only vitrified bricks, also called polished bricks). Guangdong bricks are more delicate than Jiajiang bricks of the same grade, a bit like baby skin.

4. Take the naked eye (only vitrified tiles, also called polished tiles) as an example, which are all white polycrystalline micropowder. Putting the two kinds of bricks together, the color of tiles produced in Guangdong is softer than that produced in Jiajiang. Compared with light source, Guangdong brick has better reflectivity.

5. Some brands of Jiajiang bricks are marked with the production address in a very inconspicuous place in the box (such as Jiajiang * * * enterprise, address: * * village in * * town or * * economic development zone). But not all Jiajiang bricks are marked with the production address.
