The color of the dyed stone is gorgeous, but unnatural, mainly in terms of gloss.
The level of dye penetration can be seen at the fracture of the board, and sometimes it is possible to see it with a sharp edge.
Dyeing stone generally adopts stone with poor stone quality, large porosity and high water absorption rate. It can be distinguished by tapping method. Natural stone generally sounds crisp and loud.
The oil coated with oil to increase the gloss has a grease stain on the back.
Although the gloss of the coated stone is high, the strength of the film is not enough, it is easy to wear, and there is scratch on the light.
A stone coated with wax to increase the gloss, baked with a match or a lighter, the wax surface is lost, and the original color is revealed. Wipe it with toilet paper. If the color falls, it is dyed stone.
