Factors Contributing to the Yellowing of Honed Gray Sandstone Slabs

Honed gray sandstone slabs contain microcracks and voids that fall within the range of capillary pores. These pores naturally absorb various liquids, fine dust, pollutants, and both water-soluble and oil-soluble organic pigments. The higher the porosity and water absorption rate, the more susceptible the stone is to pollution and deterioration.

Main Causes of Stone Yellowing:

1.      Insufficient Stone Protection

• Inadequate protection allows iron ions within the stone to react with water, forming iron oxide, which leads to yellowing.
• This issue is particularly common in white stone varieties such as Yashi White, Jazz White, and Large White.

2.      Contamination During Processing

• Machinery, equipment, and blade rust spots can contaminate the back of the stone, leading to discoloration.

3.      Poor Protection of the Finished Product

• Exposure to iron elements without proper protective measures can cause rust formation, which damages the stone and results in yellowing.

4.      Irregular or Improper Maintenance

• Using inferior acid-based cleaning agents can cause a chemical reaction with steel wool, allowing harmful substances to penetrate the stone's pores and cause yellowing.

5.      Use of Inappropriate Waxes or Substances

• Applying waxes containing pigments, acids, or alkalis during the grinding process can cause discoloration and yellowing over time.
