Redwood is hardwood, hardwood is not all redwood. (attached: 101 kinds of dark-colored expensive hardwood)

The National Development and Reform Commission released the “New Dark-colored Hardwood Furniture” “new line”, listing 101 dark-colored luxury hardwood furniture species.

When the standard was released, it was misunderstood that it was a revision and expansion of the national "Redwood" standard, which caused many concerns and arguments in the market.

Now the industry already knows that the two standards deal with two objects. However, for the wooden friends who have just come into contact with mahogany, many people are still vague about the concepts of "redwood" and "hardwood."

In fact, mahogany furniture is only part of dark-colored expensive hardwood furniture. In addition, although many people know that "dark luxury hardwood furniture" lists 101 kinds of suitable dark-colored expensive hardwoods, but it is rarely clear about the classification and the specific tree species, and it is difficult to find the standard on the Internet The specific tree species listed.

The dark-colored hardwood refers to the collective name of a class of commercial wood produced in tropical and subtropical regions. The characteristics of this type of wood are:

1. The material is hard, heavy, and stable in material. The difference between the heartwood and sapwood is obvious.

2, beautiful heart pattern, corrosion resistance, mostly porous material or semi-ring material.

On December 29, 2017, the National Standards Commission released information that GB/T 18107-2017 "Redwood" will replace the original "Redwood" national standard (standard number is GB/T 18107-2000), the new standard will be 2018 July 1 implementation of implementation.

However, the revised content of the new standard has not been announced. The formulation of the "Hongmu National Standard" has undergone rigorous research and discussion, and has determined the selection basis for the red wood species, mainly in the following aspects:

1. The wood anatomical angle (ie, the plant classification angle: mainly includes anatomical features).

2. The wood characteristics of the furniture fragments of the Ming and Qing Dynasties (historical and cultural inheritance).

3, the current mahogany furniture materials.

4. At the same time, refer to the timber specimens and materials that are being identified at home and abroad.

So what's the difference in the new standard of "Redwood"?

Compared with the "five, three, thirty-three, five genera" in the national standard before:

1. Pterocarpus in the rosewood class The Pterodonta rosea and Jatropha rosea are identified as the synonymous names for the large fruit Pterostilbene, not included in the Redwood species.

2. Dalbergia is a black-red rosewood in black rosewood is identified as a knife-shaped black Dalbergia synonyms, not included in the redwood species.

3. The Ponte ebony in the ebony species of persimmon is cancelled.

4. In addition, the raw hairy ebony belonging to the ebony genus of persimmon is classified as striped ebony.

5. The genus Tieki in the original chicken wing wood was changed to Cassia genus.

In detail, out of the 29 tree species, 17 tree species were listed in Appendix II of the CITES Convention, and 3 tree species were listed in the second-level protection of the State Plant List. Among them, Dalbergia japonica and Daoji Dalbergia are "double protected."

In accordance with the selection of necessary conditions determined by the multi-party research, taking into account factors such as the history and culture of China, the degree of scarcity of resources, etc., and referring to the wood specimens of well-established names at home and abroad, they were selected and named, most of which belong to rare and scarce tree species.

Therefore, with these mahogany-finished furniture, the quality of the timber, cultural heritage, and preciousness of resources basically carry the connotation of the term “Redwood” that China has used so far, and it has kept the precious, noble, and luxurious furniture of mahogany furniture. With a heavy sense of history and rich Chinese cultural taste, this is the status Redwood should have in furniture materials at home and abroad.

The following is the full text extracted from "Dark Luxe Hardwood Furniture Standard" Appendix A [Dark rare hardwood is mainly applicable commodity and tree name] , a total of 101 kinds of wood is classified as dark luxury hardwood:

A.1 Of the 43 tree species listed below, 33 were taken from the GB/T18107-2000 “Redwood” standard, most of which belonged to rare and rare tree species, and also included some of the tree species inherited from traditional furniture since the Ming and Qing Dynasties. (Annex A.1)
