stone crafts have a very mature production process and a very, very long history, but sometimes, rust spots will be found on the surface of stone crafts. In fact, there are many reasons for stone crafts to produce rust spots. For example, when raw stone crafts are processed and cut with steel grit, the steel sand contaminated on the surface of the stone crafts cannot be cleaned. After the action of water vapor, rust spots can be formed. Generally speaking, after grinding and polishing, the rust spots will not happen again.
After the stone crafts are pickled, the residual acidic substances will react with water and cause rust yellow. During installation, some iron accessories are rusted, and then spread to the surface of the stone crafts, which will also cause the surface to be rusty yellow. Because the reason for the rust spots on the stone crafts is that it contains iron minerals or foreign rust, and the rust spots are produced due to the penetration of water.
