Drip test: natural leather absorbs water obviously, and artificial leather may be the opposite.

Tension and elasticity test: natural leather has good elasticity and tension, and vice versa.

Blowing test: saliva can be used to blow on the back of leather, and there is leakage on the front. It is precisely because of this "anti-reverse performance" of leather that when you put on leather, the cold-proof effect is very obvious, forming good air permeability and fully embodying the value of leather.

Combustion identification method: mainly smell the smell of coke and see the state of ash. When natural leather burns, it will give off the smell of burnt hair, and the burnt ashes are generally fragile into powder, while artificial leather has a strong flame and rapid contraction after burning, and has a very unpleasant plastic smell. It will become sticky after burning and harden and agglomerate after cooling.
