Why are the tiles in the south black and the tiles in the north red?

1, rainy in the south, hot climate, blue bricks and tiles do not drink water, moisture-resistant, cool colors are popular; There is little rain in the north, the climate is hot, red bricks and yellow tiles draw water, and warm colors that are not resistant to tide are popular.

2. The color of building tiles is determined by the production process. There are black tiles or red tiles in the north and south. The production cost of red tiles is relatively low. Control the oxidation degree of iron during sintering. Produce more trivalent iron and the color will turn red. More ferrous iron corrects black.

3. Blue bricks and green tiles are matched with green hills and beautiful waters in the south, and red bricks and yellow tiles are suitable for the blue sky and high altitude in the north.
