Introduction of Common Redstone Painting and Its Selection Method
There are many kinds of granite, and there is a red granite product in daily life, which is very common. This kind of finished product has a nice name, called General Redstone. Generally, red stone is light red with a few irregular yellow stripes, and it is mainly composed of granite gneiss. The main producing area of common red stone is Pingyi County, Linyi City, Shandong Province, where most common red stones are produced. Because the general red stone has the characteristics of stable and unbreakable stone and good color retention, it has become a good material for decoration and simple use. Not only that, the common red stone can also be used as a sharpening stone because of its strong characteristics. After introducing the characteristics of general red stone, let's learn how to choose the right general red stone.
First of all, after we get a piece of ordinary red stone, the first thing to do is to observe. Observe whether the surface of common red stone is fine or not. If the fine material structure is relatively uniform, then this is a better general red stone. If the appearance of stone is poor and there are some natural lines such as cracks, then this is unqualified stone. This kind of stone is easy to break along these lines in future use.
The second step is to measure the size of general red stone. Because the stone we want to use should be spliced and matched with other materials, the general red stone should be measured to the right size after buying it home to avoid deviation.
Listening to the sound of knocking on the general's red stone is also an important way to distinguish good from bad. Good stone knocking sounds are crisp, while poor stone knocking sounds are dull and rough.
There is a very simple way to identify the compactness of stones. That is, take the ink, drop a drop of ink on the back of the general red stone, and then observe that if the ink can quickly penetrate into the stone, it means that the internal structure of this general red stone is loose and not suitable for purchase. On the contrary, it proves that the internal structure of general red stone is close and worth buying.
Whether the general red stone is used as a building material or a decorative material, the choice of quality is very important. Readers should use the methods described above to avoid potential security risks.
