The whiteness of the place where the water has been ground is not fake.
The green ink block will not turn white in the areas that have been ground with water. This means that after using a green ink block to smear on the paper, and then brushing it with water, the areas will turn white. This is because the green ink block is an organic pigment. When it comes into contact with water, the pigment will be activated by the water and spread to the paper, creating a whitening effect. This phenomenon is not fake and is due to the characteristics of the green ink block.
The production principle of green ink blocks is composed of some specific chemical substances. When in contact with water, a chemical reaction will occur, causing the pigment to turn white on the paper. This property is often used in artistic creation and calligraphy practice to create unique effects or to study variations in ink color rendering.
However, it should be noted that the specific whitening effect of the green ink block may be affected by different brands and qualities of green ink blocks.
