Anonymous users2024-01-24Have you noticed when buying old elm furniture, there will be a gap at the edge of the furniture desktop, most people will not doubt whether it is the size error made by the craftsman, here I can clearly tell friends that it is not, the gap is intentionally left by the designer.
Leave a gap this is the designers have ulterior motives, the gap on the surface of the old elm furniture is to curb the physical characteristics of the wood thermal expansion and contraction, he is called the "expansion joint" by insiders, that is, when the wood is subject to the outside temperature and humidity, the wood will expand, there is this expansion joint to ensure that the wood will not crack when expanding, or cause the furniture to deform and bulge, so that it affects the aesthetics of the furniture and can not be used, the expansion joint has played a huge protective role in improving the service life of the elm furniture. I don't know if when you go to a restaurant with Chinese decoration to eat, you notice that there is a gap near the edge of the dining table, which is also an expansion joint. It is a traditional processing technology of classical Chinese furniture. Elm furniture has always retained the "mortise and tenon" structure of the traditional furniture production process of the Ming and Qing dynasties, without an iron nail, and assembles various parts of the furniture through the ingenious combination of mortise and tenon joints.
It is necessary to leave expansion joints on the surface of furniture, it is also known as art joints or craft joints, mostly at the interface, and it is two different wood grain directions, in areas where climate change is more obvious, you can carefully observe the changes in these gaps, he will change slightly due to the difference in temperature and humidity.
Therefore, in order to prevent the deformation of old elm furniture and prolong the service life and aesthetics of furniture, expansion joints must be left and play a great role.
The cracking of elm furniture is due to the improper drying treatment of the wood, so that the moisture content of the wood is high, and the material cracks when the furniture is formed in dry weather or environment. >>>More

Reasons for the dryness of old elm furniture:
Because the raw materials of old elm furniture are rich in certain moisture, the air is also rich in certain moisture, but the moisture in the raw wood is higher than the moisture in the air, in the natural state, the moisture in the raw wood will be slowly lost, so that it is as common as possible with the moisture content in the air, but this is a long process, so it is necessary to carry out manual intervention, through drying furnaces and other boring equipment, to speed up the completion of this process. Let's say it's over in 20 days or about a month. >>>More
Advantages: 1. Elm furniture wood is tough and corrosion-resistant. The strength and hardness are relatively moderate, which is suitable for making carved furniture. >>>More
