Redwood does not refer to all red wood, nor does it refer to a kind of wood. It is a general term for the domestic mahogany furniture. The "Redwood" national standard stipulates that only 5 genera and 8 types of commodity materials can be called mahogany. Furniture and crafts made of mahogany have always been a favorite of people. Mahogany furniture has always been a symbol of honor and wealth in China. In recent years, with the remarkable improvement of the living standards of the Chinese people, mahogany furniture has gradually entered the homes of ordinary people. However, in the face of the numerous mahogany furniture on the market, the people are really difficult to distinguish, and they are always afraid of buying fake goods. The manufacturers and dealers are also unfounded, and even the law enforcement officers of the technical supervision department cannot rely on them. In order to standardize the materials used in the current mahogany products and promote the healthy development of the market, the State Bureau of Quality and Technical Supervision has officially released the National Standard for Redwoods, and stipulates that this standard will be implemented from August 1, 2000. To this end, the reporter visited the first drafter of the "Redwood" national standard, and Mr. Yang Jiaxuan, an associate researcher at the Institute of Wood Industry of the Chinese Academy of Forestry. The standard was formulated mainly for the name "Redwood". Mr. Yang Jiaxuan said that everyone knows that mahogany furniture began in the Ming Dynasty, which is true. In history, Zheng He went to the Western Seas seven times. He once arrived in Vietnam, Indonesia, Java and Sumatra, Sri Lanka, India and the east coast of Africa. He brought Chinese silk and porcelain to foreigners, and the main ones were redwood, because of the redwood weight. Heavy, just for the use of ballast. After the mahogany arrived in China, some skilled craftsmen used it to make furniture, which was later known as "Ming-style furniture" at home and abroad. Today, more than 98% of China's redwoods are imported. Due to years of excessive logging in foreign countries, precious redwood resources have been decreasing year by year. Therefore, the supply of domestic redwoods is relatively tight. Some furniture manufacturers have made profits in order to make profits, or purchase old mahogany furniture, or substitute other woods with similar import quality. In this way, there is a wide variety of mahogany furniture on the market, so that consumers can not understand the details. Not only that, the name "Redwood" itself has not been scientifically and strictly defined, and it is very confusing to use. The common sayings about mahogany on the market include mahogany, fragrant mahogany, old mahogany, new mahogany, red sandalwood, and Venus rosewood. More than 20 names such as bovine hairy rosewood, rosewood, new pear, huanghuali, purple pear, red rosewood, black rosewood, white rosewood, ebony, chicken wing wood, iron power, copper rough, iron rough. Not only that, but also the same kind of synonyms or synonyms of the same kind. For example, some people who call the local curl of sandalwood rosewood are called bovine rosewood, and those who are filled with gum are called Venus rosewood. In fact, they are all the same kind of wood. All of the above non-standard names have brought great difficulties to consumers and market managers in identifying mahogany furniture. Therefore, everyone is eager to ask the relevant state departments to give an authoritative statement. We have formulated this "Redwood" national standard, which is to be the name of "Redwood".
