Why White Marble Turns Yellow？

A new study has identified the pollutants that turn the marble of India's iconic Taj Mahal yellow. The pollution that has caused the white marble on the world's largest marble mausoleum in the country's capital to turn yellow has severely affected the TajMahal, India's "biggest attraction." After initially turning yellow, the once immaculate white marble stones of this cemetery have now turned green, "a court ruled on May 1.  

The interesting phenomenon is that it occurs when it is placed in water that has been shown to be closely related to moisture. Water accelerates the oxidation process and can turn yellow relatively quickly when the water is evenly applied. The more I researched the subject, the more it seemed that yellowing was more common in white marble than in any other type of marble, especially when exposed to excessive humidity everywhere, such as on the ground or in the air. 

However, most yellowing is caused by layers of wax that can turn yellow in various ways, such as by using a layer of wax. If layers of wax are repeatedly applied and embedded on the marble over a long period of time, the marble itself turns yellow as it is. 

Improper cleaning causes dirt to collect in the pores of the marble and be carried through them. This dirt makes the surface of the white marble appear yellow and causes its surface to become dirty and yellow. The dirt, brought in by a dirty mop, accumulates in the pores of the marble, making the surface of the marble yellow or dirty. Dirty pug brings dirt to the surface and collects dirt in the porous areas of the marble, causing the marble surfaces to turn yellow, dirty and yellow. 

There are several reasons why a stone turns yellow, but certain stones naturally turn yellow with age. Embedded dirt and dirt can give the stone a yellow or dirty appearance, wax and other coatings can turn yellow with age, so that certain types of marble can cause this. Some white marble tiles can remain yellow for years and then slowly turn yellow over time and, after some serious causes, turn completely brown. Certain white marble will naturally turn yellow as they age and some waxes or other yellow coating agents with aging, certain marble stones may turn yellow and remain, then over time they may slowly turn yellow or, if severe and without serious cause, may turn completely brown and completely brown or even completely yellow. 

White marble tiles can remain yellow for years and then slowly turn yellow over time or completely brown after some serious causes. The above story is not uncommon, but it is because the white marble tile was subjected to flooding. While flooding is a common cause of yellowed white marbles, there are several other reasons why this change in color will occur. 

Water stains are very common when drinks are left in the marble and hard water forms in sinks, marbles and showers. 

When iron deposits in white marble are exposed to large amounts of consistent water sources, yellow and brown spots may occur. Once oxidized, iron discolors the polished white marble and stone and leads to its oxidation. Iron in the stone can oxidize and turn the stones yellow when exposed to high temperatures, high humidity and high acidity. When hydrochloric acid or bleaching iron oxidizes in a stone and the stones turn yellow. When iron oxidizes in white marble and is released by a large volume or even water source, a yellow or brown stain is created on the surface of the marble.  

Yellowing in white marble caused by external causes can be prevented by placing a fibre carpet at the entrance to remove sand and other hard particles from penetrating the marble paving area and reducing external hard particles. Pay attention to the beauty and decoration that white marble can perfectly accentuate, as well as the color of the stone. 

To prevent the white marble floor from turning yellowish, choose a marble cleaner that is harmless and toxic - free. Finally, if you want to use white marble or lighter stone, use a clean, non-toxic marble cleaning solution. When it comes to removing stains from white marble and granite counters, use the same cleaning agents as any other stone or marble. 

If you apply this process to a white marble floor that contains moisture, it will turn the marble yellow, although it is not toxic to the floor. If you apply this process to a white marble floor cleaner, a process that does not cause yellowish stains, the process will not turn your marble yellow. 

If you suspect yellowing due to improper maintenance, you must clean your marble tiles with an alkaline marble cleaner. Keep dry: After you have finished cleaning marble floors and countertops, leave a little water on the marble surface until no stains have appeared on it. If you suspect yellowing due to proper maintenance: If you suspect yellowing due to improper maintenance, you will need to clean marble tiles with alkalis and marble cleaners, and you will also use a white marble floor cleaner and a water-free marble cleaner. Cleaning marble tiles: You can also clean marble tiles with alkaline marble cleaners.
