Elm is tough in texture, clear in texture, moderate in hardness and softness, suitable for general relief carving, smooth in planing, beautiful in chord pattern, and has "chicken wing wood" pattern, so it is one of the main furniture materials.

Carbonized wood is divided into surface carbonized wood and deep carbonized wood. Wood with carbonized surface is barbecued with oxygen torch, so that there is a thin carbonized layer on the surface of wood. The change of wood properties can be similar to wood paint, but it can highlight the uneven wood grain on the surface and produce a three-dimensional effect. Applications focus on handicrafts, decorative materials and aquarium products. Also known as craft carbonized wood and charcoal burned wood.

Deep carbonized wood is also called fully carbonized wood and homogeneous carbonized wood. It is wood treated by high temperature carbonization technology at about 200 degrees. Because its nutrients are destroyed, it has good anti-corrosion and insect-proof functions. Due to the recombination of water-absorbing functional group hemicellulose, the product has good physical properties. Deep carbonized anticorrosive wood is a real green product. Although the product has anti-corrosion and insect-proof properties, it does not contain any harmful substances, which not only prolongs the service life of wood, but also does no harm to human body, animals and the environment during and after use. Deep carbonized wood has been used in Europe for nearly ten years, and it is the main substitute product after CCA is banned. Deep carbonized anticorrosive wood is widely used in wallboard, outdoor floor, kitchen decoration, sauna room decoration, furniture and many other aspects. However, contact with water and soil is not recommended.

Nowadays, furniture is assembled with a variety of solid wood, and a single kind of wood is rarely used. You can go to some big furniture websites to have a look.
