Talk about sour branches
What is the acid branch, which I personally think should belong to the two columns of the genus of yellow sandalwood in the five genera of mahogany, the red acid branch. In the 2000 national standard mahogany, there are eight kinds of black acid branches, seven kinds of red acid branches, and in the new version of the 2018 national standard redwood, the black sandalwood in the genus of black acid branches in the new version of the national standard redwood was identified as a synonym for knife-shaped black sandalwood and was eliminated; Today it has been reduced from fifteen acid branches to fourteen acid branches.
Acid branches into the national standard mahogany standard is quite strict, ancient sitting acid branches, sleeping rosewood saying, through density analysis, dry year acid branches, a hundred years of pear said, is the existence of physical phenomena dialysis natural phenomenon, so the acid branch is more expensive than the pear class, here I still want to say a single broad-leaved yellow sandalwood, in fourteen kinds, only one of its materials is lighter than rosewood, why in this statement, because I am afraid that I will mislead people, all the broad leaves as high-grade materials, in fact, it does not have the density conditions into the black acid branches.
Requirements for black acid branches:
1. Dalbergia tree species.
2. The wood structure is thin to very fine, and the average chord diameter of the pipe hole is not more than 200 μm.
3. When the moisture content of wood is 12%, the dry density of gas is greater than 0.85g/cm3.
Red acid branches are required:
1. Dalbergia tree species.
2. The wood structure is thin to very fine, and the average chord diameter of the pipe hole is not more than 200 μm.
3. When the moisture content of wood is 12%, the dry density of gas is greater than 0.85g/cm3.
4, the heartwood of the wood, the color of the wood is reddish brown to purple red.
Mahogany is through five levels and six generals, through layers of screening, but there is still broad-leaved yellow sandalwood and rosewood in the Indian rosewood, there is a controversy, so it is really not easy for experts to find, classification, assessment density, wood cells and so on.
Black red rosewood, wood properties must be sandalwood genus, which is the first major condition. Speaking of which, I'll list the seven types of black acid branches (knife-shaped black sandalwood, broad-leaved yellow sandalwood, Lu's black sandalwood, East African black sandalwood, Brazilian black sandalwood, Amazon yellow sandalwood, And Belize yellow sandalwood). )。 There are seven kinds of red rosewood (Barry Yellow Sandalwood, Saizhou Yellow Sandalwood, Cross-toed Yellow Sandalwood, Fluffy Yellow Sandalwood, Central American Yellow Sandalwood, Austinum Yellow Sandalwood, Slightly Concave Yellow Sandalwood. ), all listed one by one, as long as there are fourteen names included, it is the wood that can be called acid branches.
African acid branch, East African acid branch, South American acid branch, Cambodian acid branch, which is commonly used in the market so-called acid branch wood, in fact, it is a non-national standard in the hardwood class, African acid branch, East African acid branch Its wood properties are su wood, collectively known as ancient Yi su wood. South American sour sprigs are saber wood, broad-pitched beans, belonging to paraguayan sumac, also a type of sativus. The Cambodian sour branch, Lamella sativa, is actually part of the genus Oleander in the family Junziaceae. These four common woods are three different genera, and the acid branches of the genus Xanthorax are not marginal, but their density is large, the color of the wood is close to the acid branches, and the factory wants to hitch a ride on the mahogany, easy to buy and easy to raise the price, it gives a common name, acid branches, but it is a false acid branch.
There are also some uncommon sour branches, all of which are boo heads, which is not surprising. So, if you buy mahogany, don't come to a general name, I want sour branch furniture, it is best to name what acid branch, so that the factory can easily convert the cost.
Three years ago, a dealer, my Barry Yellow Sandalwood, who didn't even know, actually recognized it as an African acid branch, told me that ten sets of thirty thousand, let me directly expel me from the mall.
