One difference between granite and marble is the stone characteristic. The way to distinguish marble and granite with naked eyes is to look at their strips and patterns. Both granite and marble have patterns on them, while they are different in nature. Granite is an igneous rock, while marble is metamorphic, so their patterns are obviously different. Marble patterns are varied with smooth and enjoyable strips and lines rich in color. However, the granite pattern is mottled and relatively simple without obvious pattern formation. Granite is of medium hardness, while marble is a soft stone with less hardness than granite. However, this also leads to the limitation of granite plasticity, while marble is easy to process and more widely used in decoration design.
The second difference between granite and marble: different range of application.
The most obvious difference between granite and marble is that one is used outdoors and the other is used indoors. Most of the patterned natural stones seen indoors are marble, while the speckled natural stones laid on the outdoor pavement are granite. Why is there such an obvious distinction between places? The reason is that granite is hard-wearing, acid-resistant and corrosion-resistant, and can be used for a long time even in wind and sunshine. In addition, granite can be divided into three categories A, B and C according to its radioactive level. Class A, which can be used in any occasion, including office buildings and family rooms; Class B products are more radioactive than Class A and cannot be used for interior finishes of living rooms, but can be used for interior and exterior finishes of all other buildings. Class C products have higher radioactivity than Class A and Class B, and can only be used for exterior finishes of buildings. Natural stones that exceeds standard control values of Class C can only be used for other purposes such as seawalls, piers, steles. As a contrast, marble patterns are beautiful and suitable for interior decoration. Marble material is exquisite, bright and clean as a mirror, and has strong ornamental value, so it is widely used in the art field. In the Great Hall of the People there is a huge and exquisite marble screen. The radiation of marble is too weak to be noticed, and all the marble carcinogenesis infomation spread on the Internet is rumor.
The third difference between granite and marble is the price.
Although granite and marble are both high-grade stone products, their prices vary greatly. Granite pattern is single, with little color variation and poor decoration. Its advantages are firm and durable, not easy to be damaged or dyed, which is mostly used outdoors. Granite ranges from tens to hundreds of yuan, with cheaper rough surface and more expensive smooth surface. Marble has smooth and exquisite texture and rich pattern variation. Fine works have charming patterns like landscape paintings. Marble is the stone of artistic value. The price of marble ranges from hundreds to thousands of yuan. According to different producing areas, the price of products with different quality varies greatly. The difference between the two is still evident in the characteristics, effects and price. Hope that the above content will be helpful for you to distinguish marble from granite, and make a clearer decision when choosing and buying.
