Generally, the diploma is made of leather, and buyers usually ask how to distinguish the cover of the leather certificate from real leather and leather. Next, we will have an introduction to the common and simple ways to identify genuine leather and leather, including touching, observation, smell, and ignition.
If the surface of the leather diploma cover is smooth (except the grain is processed into a thick leather), soft, plump, and elastic, it is the real leather.
Observation means identify the type of leather and the quality of the leather grain.
When observing, people can find that there are obvious pores on the surface of the dermis and there are dermal fibers on the back of the patterned skin. Although synthetic leather also imitates pores, it is not realistic and unclear. Besides, the reverse side of synthetic leather has a layer of the textile as the base plate. This textile base plate is used to increase its tensile strength, while the reverse side of real leather does not have this layer of textile. What can be distinguished is the cross-section of the cover of the leather certificate. You can see the difference when the leather is cut. The leather is woven and arranged with sparse to dense fibers. The leather layer is very tight and resistant to nail scratches and hard objects. The leather is hard to crack. The second layer is just a thin layer of film on the surface of the nail, which separates from the leather once it is torn. It is the simplest and most practical way of identification.
Good quality leather generally has no peculiar smell. All genuine leather has the smell of leather. If there is a pungent peculiar smell, it may be caused by poor handling in the tanning process and certain chemical raw materials, not environmentally friendly chemical products, or excessive use.
The smell of ignited real leather is similar to that of hair ignited, and it does not form lumps after burning. It can be ground into a powder with fingers. Artificial leather emits a pungent odor when ignited and forms lumps after burning.
