First of all, look at the legs and feet of the furniture for signs of fading and soaking. In the humid areas in the south, furniture is usually placed directly in the mud, which will happen after a long time.
Secondly, see if the patina is natural. Generally, there will be natural patina in the position where the user's hands often contact. The new imitation patina is either unnatural or made in a place that is not often touched.
Again, look at the copper live parts. If the copper pieces of old mahogany furniture are original, it will take decades or even hundreds of years to polish by hand. Copper movable parts include face pages, hinges, handles, corners, panels, locks, etc. Some furniture with better materials will be made of white copper, which will give off a faint silver light after a long time, which makes people think. Some copper moving parts have various patterns, such as animals, flowers and auspicious words. And the craft is fine, which is difficult for coppersmith to imitate now. On some patterns with strong folk interest, we can also distinguish the regional customs and the fashion of the times, thus obtaining precious humanistic information.
Then, look at the decoration traces. After renovation, some cloth chairs will leave many nail holes in the original chair ring. This kind of chair is old. Some rattan chairs, the original rattan surface rotten, will leave rattan eyes, you can see it when you turn it over.
Then, look at the wood grain. Some furniture will have uneven wood grain on the surface, but we should look carefully to see if it is hard rubbed out with a wire brush and whether it is worthy of the original wood grain. Hard-ground wood grain always has an unnatural feeling.
Finally, look at the bottom plate and drawer plate of mahogany furniture. Such as old tables and stuffy cabinets. , the bottom plate and drawer board have imitation old gas. There is also matte black paint, but it is absolutely lifeless. Then look at the side panel of the drawer. There should be a chamfer line on the side to avoid hurting your hand. It is also important to look at tenons. The tenon used to be square, and the tenon was locked by a pin. If you see that both ends of the mortise are round, it means that it is machined and must be a new imitation.
