How to distinguish the natural color and dyeing treatment of granite?
Granite, as a common building material, is widely used in fields such as home decorations and furnishings, building construction, and roads due to its hardness, durability, diverse colors, and excellent texture. With the development of technology, many businesses often use dyeing techniques to make the color of granite more vibrant or meet specific needs. The dyed granite has a more uniform and bright color, but its quality and durability are different from natural granite. 1. Uniformity of color of granite The color of natural granite usually has a certain degree of non-uniformity, which is due to the influence of geological environment during its formation process. The mineral composition and structural distribution are not completely consistent, resulting in natural differences in surface color and texture. The color changes of natural granite are usually manifested as spots, veins, or subtle transitions, giving a natural and layered visual effect. Granite that has undergone dyeing treatment usually presents a more uniform color. This color is usually artificially controlled, and the color distribution will be more consistent and saturated. For example, the surface of dyed granite may exhibit overly consistent color regions without the natural variations unique to natural hues. If it is observed that the entire surface color is very uniform and lacks color difference changes, it is likely that it has been dyed. 2. Observe textures and patterns of granite The texture and pattern of natural granite have unique natural properties, and they are usually irregular, exhibiting obvious naturally formed cracks, mineral veins, spots, and other characteristics. The texture of dyed granite often appears relatively simple or repetitive, and dyeing may mask some details on the surface of natural granite, especially in terms of texture changes. Dyeing treatment usually involves the infiltration of dyes into the surface of stone, causing a change in the color of the stone, and this dye does not alter the internal structure of granite. Therefore, observing the changes in texture and corresponding details often reveals traces of dyeing treatment. For example, if you see the same veins or spots appearing regularly on the surface of the stone, it may be the result of artificial dyeing. The texture of natural granite is unique and does not exhibit large areas of repetitive patterns. 3. Observe the depth and distribution of colors of granite Stained granite usually presents bright and saturated colors due to the influence of the surface staining layer. For granite with dark tones, the color of the dyed stone will appear darker and even glossy. The color of natural granite is relatively more natural, with less intense and softer hues. Especially in some dark colored granite, the surface of natural granite may have uneven color and slight fading. In addition, the color distribution of dyed granite is usually mor...
