redwood furniture

Mahogany furniture (English scientific name: mahogany furniture) began in the Ming Dynasty. Its appearance is simple and symmetrical, and its natural color and texture are pleasant. Mahogany mainly adopts traditional techniques such as carving, mortise and tenon, inlay and curve made by China furniture. German scholar G Ecker summed up three basic laws of mahogany furniture processing in Textual Research on China mahogany furniture: it is not necessary to use wood sales; Try not to glue where you can avoid it; There is no need to rotate anywhere. That is, without any nails and adhesives. Therefore, the obvious nationality of mahogany furniture in shape and technology is the most attractive part for many collectors. Many people call mahogany furniture humanistic furniture and artistic furniture.

According to the relevant regulations of the State Bureau of Technical Supervision, the so-called mahogany furniture mainly refers to furniture made of rosewood, rosewood, ebony, beech, rosewood and chicken wing wood, and furniture made of other wood cannot be called mahogany furniture. Rosewood is the best among redwoods. Its wooden solid mahogany furniture

Hard, purple-black in color, noble and heavy to the touch. The annual rings are silky, fine in texture and irregular in crab claw patterns. Red sandalwood is divided into Roshi wood and new red sandalwood. The old rosewood is purple-black, which does not fade when soaked in water, while the new rosewood is reddish brown, dark red or deep purple, which will fade when soaked in water. Acid rosewood is commonly known as old mahogany. Wood is hard and heavy, durable, can sink into water, and has a fine structure with lemon red, deep purple and purple-black stripes. It gives off a pungent sour taste during processing, hence the name. Ebony is black and shiny, with fine and dignified structure and a sense of grease. Ebony is mostly used to make small items such as chopsticks and ink cartridges, but it is rare to make furniture. Gall wood is the wood after gall formation, which can be divided into birch gall, nanmu gall, Dalbergia odorifera gall and acid branch gall according to tree species. Beech is the best decorative material because of its patchy texture curve and unique appearance. It is often used as the surface wrapping and inlay material on furniture, such as the folk saying "red beech face". Rosewood, also known as rosewood, is similar to rosewood. Its wood is hard, the color is red, yellow or purple, the texture is rain grain, the color is soft and the weight is light. It can float in the water and looks like a wooden rib. At present, most mahogany furniture on the market is rosewood. Chicken wing wood is hard, and its colors are black, white and purple, like chicken wings and feathers, and its colors are bright and bright. However, because wood contains impurities such as fine sand, it is difficult for the enemy to process it, so it is good at making decorative corner materials. It is difficult to see complete sets of chicken wing wood furniture in the market. For example, there are only a few precious tropical hardwoods listed in the national redwood standard: red sandalwood, Huang Huali, ebony, sour branch, chicken wing wood, fragrant wood and so on. And these precious wood, some have not been produced naturally for a long time, and some have little output. In addition to the high market price, customers must always be alert to the flood of counterfeit and shoddy products. Therefore, the traditional mahogany furniture market is shrinking. It is of little significance to make traditional solid wood furniture with ordinary wood. Mahogany furniture can be divided into full mahogany furniture, main mahogany furniture and mahogany veneer furniture according to product materials. 1. All mahogany furniture means that the wooden parts of the product (except mirrors, mirror plates and lines) are all made of mahogany; 2. The main part of mahogany furniture means that the visual part of the product appearance must be made of mahogany, and other dark and precious hardwood or other high-quality wood can be used in the interior and hidden places; 3. Mahogany painted furniture means that the visual part of the product is covered with mahogany solid board, and other similar high-quality wood can be used in the interior and hidden places, but the quality guarantee provided should clearly indicate the main components and the specific parts of the covered mahogany furniture. Sequoia grows slowly, is short of resources, and decreases sharply year by year, and some of them are facing extinction. Domestic redwoods are not only few in variety, but also extremely low in output. The mahogany furniture produced and used in China comes from India, Myanmar, Thailand, Vietnam, Laos and other Southeast Asian countries and South America.

Imported from Europe and tropical Africa. With the growing voice of international environmental protection, these countries have adopted strict policies to restrict products, so the import channels are increasingly narrow and difficult. It is predicted that these precious woods will not be available for several years. By then, people will be very rich and it will be difficult to buy such luxurious and precious mahogany furniture. Mahogany furniture can be divided into traditional hardwood furniture and modern hardwood furniture 1. Traditional hardwood furniture refers to exquisite dark and precious hardwood furniture with classic Ming and Qing hardwood furniture as its main technology and style and display and collection as its main function. Generally refers to hardwood high imitation furniture, mahogany classical furniture, classical craft furniture and so on. Traditional hardwood furniture can be divided into: chairs, desks, cabinets, folding beds, screens, seats, tables and shelves. 2. Modern hardwood furniture A. refers to dark and precious hardwood furniture with intellectual property rights and collection value, which not only embodies traditional furniture art, but also has contemporary artistic innovation, exquisite material selection and exquisite production. Generally refers to hardwood (mahogany) art furniture, new Shanghai style furniture, etc. B, refers to the traditional craft and practical function, pays attention to the innovation of product style, craft and structure, and has the artistic style of Ming and Qing furniture, including dark and precious hardwood veneer furniture and soft furniture. Modern hardwood furniture can be divided into bedroom furniture, living room furniture, dining room furniture, study furniture, office furniture, hotel furniture and so on.

Edit the price increase factor in this paragraph.

As for the prospect of the future mahogany furniture market, the expert analysis of famous mahogany pointed out that due to the extremely slow growth of mahogany raw materials, it often takes decades for a set of mahogany furniture to sell for more than10 million yuan in 2005.

Even hundreds of years to grow, so scarcity will inevitably make its price more and more expensive. For example, Huang Huali is the best redwood, and it takes hundreds of years to grow. At present, the price per kilogram has reached ten thousand yuan. For example, the value of black rosewood in Southeast Asia is second only to Huang Huali and rosewood, and the price is also rising rapidly. In addition to the price of raw materials, the scarcity of craftsmen and the rising labor costs have also invisibly pushed up the price of mahogany furniture. A famous rosewood expert gave an example to the reporter: it takes at least one year for an ebony bed to be designed and made, and the wages of designers, carpenters, sculptors and so on are not cheap. Take the sculptor as an example. According to the daily 200 yuan calculation, he can get more than 70,000 yuan a year, and this salary level is also rising.

Edit this mahogany classification.

Redwood has been cherished by people since the Ming and Qing Dynasties. Mahogany originated from Zheng He's seven voyages to the West in Ming Dynasty (1405). Every time he goes home, he uses mahogany ballast. Carpenters re-made hard, delicate and good mahogany into furniture and handicrafts for emperors to enjoy. Later, a large number of mahogany was imported and mahogany furniture-octagonal arhat bed was used.

It didn't flow into the people until the end of the dynasty. "Redwood" does not mean all redwoods, nor is it a kind of wood, but a general term commonly known as the current domestic redwood wood agreement. According to the definition of national standards, its scope is five genera and eight categories. Five genera: Pterocarya stenoptera, Dalbergia odorifera, Persimmon, Asparagus, Aralia elata. Eight categories: rosewood, rosewood, rosewood, rosewood, ebony, striped ebony and wingwood. Dalbergia odorifera: It belongs to Dalbergia odorifera, also known as Dalbergia hainanensis and Dalbergia odorifera, commonly known as Huanghua pear. It is a rare tree species endemic to Hainan, China, which has basically disappeared. Its wood is hard, the color is unknown, the visual sense is excellent, the texture is hidden or present, vivid and changeable, and it has the effect of lowering blood pressure and blood fat. The color of huanghuali is mainly yellow, and it is woven into beautiful natural patterns with dark wood grains, such as faces and fox spots, which reflect golden light and emit fragrance under bright light. Huanghua pear has a shiny surface and a spicy aroma; Fine and uniform structure, high corrosion resistance; So it is very precious. Red sandalwood: Its wood grain is "ghost face" or "beaver spot", also known as "beaver" and alias: rosewood. Red sandalwood is distributed in tropical areas of India and Southeast Asia. Its characteristic sapwood is yellow-white to grayish brown; The core material is light tan, orange brown, reddish brown to purple brown; The material has uniform color, dark luster, rain line texture, soft color and light weight, and can float in water. Rosewood is the main material of mahogany furniture at present because of its moderate price. Rosewood: also known as "Qinglongmu". Rosewood, a rare treasure, is known as the "king of wood" by the world. Rosewood grows in tropical jungles. Because of its unsurpassed material and slow growth, it is a kind of hardwood that grows one inch in a hundred years and can't be finished in a hundred years. In addition, the output of rosewood is extremely low, so it is very precious. Since ancient times, it has been called "inch sandalwood inch gold". Acid rosewood: commonly known as "old redwood", distributed in tropical and subtropical regions. Because it emits a pungent smell with sour taste during processing, it is named Suanzhi. There are two kinds of rosewood: black rosewood and red rosewood. Black rosewood: heartwood is purple-black, deep purple and reddish brown with black stripes. It is rare and expensive. Once polished and smooth, it gives people a mellow and subtle aesthetic feeling, and its value is second only to rosewood. Red rosewood: the growth rings are obvious, and the heartwood is orange-brown, purple-red-brown and deep purple. Wood is hard and heavy, generally submerged in water, with purple-black stripes, landscape patterns and grease. It is a good material for making furniture and handicrafts. In view of the upsurge of mahogany furniture and collection with soaring prices in recent years, the insiders pointed out that mahogany furniture involves 5 genera and 8 species, and its long-term value is determined by different growth cycles and wood characteristics. The range of redwood is determined to be 5 genera and 8 categories. These five genera are Pterocarya stenoptera, Dalbergia, Persimmon, Leguminosae and Aralia. Eight categories of wood are named after their trade names, namely rosewood, rosewood, rosewood, rosewood, rosewood, ebony, ebony, striped ebony and wingwood. Mahogany refers to the central part of these 5 genera and 8 categories of wood. Other wooden furniture cannot be called mahogany furniture. Red sandalwood: Red sandalwood is a fine product in mahogany, mainly produced in India, with a growth period of about 500 years. Wood is purple-black, with high density, high hardness and very delicate feel. At present, the mahogany furniture in circulation in the market was shipped back to China from India and South Africa in the Ming and Qing Dynasties. There are few bulky products, mainly arhat beds, writing desks and bookcases. The market price is 400,000 yuan to 6,543,800 yuan per ton. Huang Huali, Hainan: Redwood "Gentleman", the supply of raw materials has been cut off. Among all mahogany furniture, Huang Huali is the most exquisite tree species, with high oil content, good luster and smooth texture, and is called the "gentleman" in wood. At present, the best Huang Huali on the market comes from Hainan, and the original Huang Huali wood has been cut down. The new species of trees are only finger-thick, which is prohibited by the state, and the supply of Huang Huali has been cut off. Huang Huali furniture in Hainan can only be redesigned by buying old furniture, and Huang Huali in Vietnam and other places has also become a hot commodity in the market. The growth cycle of Huang Huali is about 500 years, and the price of Huang Huali is mostly1-2.5 million yuan/ton. Huang Huali is about 600- 1 10,000 yuan per ton. Lushi ebony: At present, there are few Lushi ebony on the market, and the price per ton is between 80,000 and 90,000 yuan. Rosewood: jealous wood, natural air freshener. As long as the nose is close to mahogany furniture, there will be a pungent sour taste, which is divided into black acid branches, flower acid branches and big red acid branches. Each sour branch has a different color, texture and texture. The growth cycle of acid tree is about 300 years, and the market price is 40 thousand yuan to 80 thousand yuan per ton. Chicken wing wood: "when those red berries come in spring", named after the texture. Chicken wing wood is also called "red bean wood", and the poem "When those red berries come in spring, wash your southern branches" is a metaphor for it. Among many kinds of wood named by color, only Pterocarya cristata is named by internal texture. The longitudinal section of pteridoptera is purple-brown striped. At present, the best wingwood in the world is produced in Myanmar, and the wingwood land in Africa is not as good as that in Myanmar. The growth cycle is generally around 100 years, and the stock of African wingwood is relatively large and the price is not high. At present, the price per cubic meter is between 5800 yuan and 10000 yuan. Burmese rosewood: There are also many stocks. The price of materials with a diameter of about 35cm and a length of about 4m is about 1.4 million yuan, with little fluctuation. The price of a material with a diameter of 50cm is about 6.5438+0.8 million yuan.

Edit the characteristics of this mahogany.

1. rosewood, alias "Qinglongmu", is a subtropical evergreen tree of Butterfly Family, with five or six feet high, butterfly-shaped compound leaves, winged fruit, hard wood and red color. Rosewood sinks when it enters the water. Rosewood is a particularly hard and heavy tree species in Leguminosae, and it is the most advanced material in mahogany. This is a deep purple hardwood. It is most suitable for making furniture and carving artworks. Articles made of rosewood have a satin-like luster after polishing without painting oil. So some people say that everything made of rosewood is cherished by people. Rosewood is hard, purple-black, dignified, heavy to the touch, with silky ring patterns, delicate texture and irregular crab claw patterns. Rosewood is divided into old rosewood and new rosewood. The old rosewood is purple-black, which does not fade when soaked in water, while the new rosewood is reddish brown, dark red or deep purple, which will fade when soaked in water. 2. rosewood is commonly known as old mahogany. Wood is hard and heavy, durable, can sink into water, has a fine structure, has lemon red, deep purple and purple black stripes, and emits a pungent sour taste when processed, so it is called red sandalwood. Sour branches are the main raw materials of mahogany furniture in Qing Dynasty. Furniture made of sour branches, with a little paint, will still look brand-new even after hundreds of years. It can be seen that the excellent quality of rosewood has already attracted worldwide attention. Suanzhi is a tropical evergreen tree, mainly produced in India, Vietnam, Thailand, Laos, Myanmar and other Southeast Asian countries, and originated in Fujian, Guangdong, Yunnan and other places in China. Rosewood comes in two colors: deep red and light red. Generally, rosewood with "grease" has excellent quality, fine structure, hard and heavy nature and can sink in water. It is particularly obvious that the dark brown or mahogany sofa with a price of 39.8 million yuan is often sandwiched with crimson.

Black stripes, clear and changeable texture. Sour branch furniture is polished and painted, smooth and lubricated, with lasting luster, giving people a pure and implicit aesthetic feeling. Sour branches are called "mahogany" in the north and "old mahogany" in Jiangsu and Zhejiang, so almost all sour branch furniture is called mahogany furniture or old mahogany furniture except Guangdong. A lot of mahogany furniture in Qing dynasty is sour branch furniture, that is, old mahogany furniture. Especially in the middle of Qing dynasty, it was not only large in quantity, but also good in wood and exquisite in production technology. In the eyes of modern people, it is real mahogany furniture. 3. Ebony is black and shiny, with a fine and dignified structure and a sense of grease. Ebony is mostly used to make small items such as chopsticks and ink cartridges, but it is rare to make furniture. 4. rosewood, also known as rosewood, is similar in composition to rosewood. Its wood is hard, the color is red or purple, the texture is rain, the color is soft, the weight is light, and it can float in water, like a wooden rib. At present, most mahogany furniture on the market is rosewood. History can be divided into at least two types. One is the red sandalwood described in Wang Zuo's "New Gegu Yaolun" in the middle of Ming Dynasty, which is "fragrant and purple, and its flowers have a ghost face", that is, the so-called "red sandalwood, red and purple, seems to be fragrant and slightly fragrant", which obviously exceeds the concept of "redwood". Judging from various materials, Huang Huali is mainly produced in Hainan Island and South China Sea, and it is one of the most important materials for Ming-style furniture. The other is red sandalwood, which is called "old red sandalwood" in the north, but it is actually "new red sandalwood". This kind of rosewood is called "redwood" in Taiwan Province Province. It is a kind of Gao Qian, with a height of more than 30 meters and a diameter of about 1 meter. Produced in tropical and subtropical areas such as Thailand, Myanmar and Nanyang Islands. In the past, Hainan, Guangdong and Guangxi also had a considerable number of rosewood. This kind of rosewood is recorded in the Natural History: "The leaves are like pears but not solid, the wood color is red and purple, and the texture is delicate. Can be used as utensils, tables and chairs, and study. " Chen's taxonomy also said: "Pterocarya is a red bean, and its height can reach 18 feet to 30 feet ... Zhejiang, Fujian, Guangdong and Yunnan. There are many Izumi and Zhangzhou in Fujian Province ... Wood is strong and beautiful, and it is used in fine furniture. " Many mahogany furniture in the Qing Dynasty was actually made of these rosewood. Modern mahogany imported from overseas is mostly this kind, which has become the most important material of mahogany furniture. However, according to the records in the Tribute to the Western Regions written by Huang Province in Ming Dynasty, it has long been considered that there are two kinds of rosewood: one is rosewood and arbor, which are produced in all parts of southern China; One is Dalbergia hainanensis, a deciduous tree, which is produced in the South China Sea. Both can be used as high-grade furniture. Hainan sandalwood is Huang Huali, so in addition to Huang Huali furniture, there should be mahogany furniture in the Ming Dynasty, which is what we call mahogany furniture today. Chicken wing wood is also called "red bean wood", and the poem "When those red berries come in spring, they flush on your southern branches" is a metaphor for it. Wood is hard, and the colors are divided into three colors: black, white and purple. It looks like chicken wings and feathers, and the colors are bright and bright. However, due to impurities such as fine sand, it is difficult to process, so it should be used as decorative corner materials. It is difficult to see complete sets of chicken wing wood furniture in the market.

shopping tips

Smell: Except all solid wood furniture, most of the wooden furniture sold on the market now are wood-based panels. Therefore, it is particularly important to smell when shopping. If people cry and sneeze, it means that the formaldehyde emission from furniture is relatively high, and there may be problems. Don't buy it. Read the report: the consumer asks the dealer for the quality inspection report to see if the formaldehyde emission of furniture is within the allowable range of the standard. The national standard "Limit of harmful substances in wooden furniture for interior decoration materials" stipulates that the formaldehyde emission in wooden furniture shall not be greater than1.5 mg/L. If the formaldehyde in the purchased wooden furniture exceeds the standard, don't buy it. It is recommended to buy furniture with e 1 standard plates. Only the boards that meet the e 1 standard can be truly harmless to human body. Ask the price: Most of the wooden furniture with formaldehyde exceeding the standard uses cheap wood-based panels, so the price of the whole set of wooden furniture is often "ultra-low". Because cheap wood-based panels use a lot of inferior glue, the formaldehyde emission is seriously exceeding the standard. Signing a contract: when customers buy furniture, it is best to sign a furniture sales contract and write environmental protection clauses into the contract. Invoicing: At present, a large number of consumers leave with white slips and receipts under the temptation of low prices of dealers. However, when complaining about quality problems, such irregular invoices are often difficult to be used as effective evidence, so dealers must issue formal invoices when buying furniture.

Precautions for purchase

First, we should choose famous and trustworthy shops, manufacturers and time-honored brands. Generally speaking, the quality of their products will be guaranteed, and the after-sales service is also very good, so there is no worries. Two, to shop around, for the same style, the same brand of goods, from the quality, price, service and other aspects of comprehensive consideration. As the saying goes, "No pains, no gains", and really good things can't be very cheap. Take the mahogany furniture of Dingtan as an example, all of them are hand-carved from top mahogany from Southeast Asia. Even a mahogany chair costs ten thousand yuan. Therefore, the biggest taboo to buy mahogany furniture is to covet petty advantages. Third, all mahogany furniture is disassembled with tenons and mortises, so real mahogany furniture does not need a little glue or a nail, which is conducive to preventing mahogany furniture from cracking. Nowadays, there are many "fakes" in the mahogany furniture market. Without certain identification knowledge, it is difficult to find good goods in the market, and you will be cheated if you are not careful. Ziyunxuan China Design Network summarizes the experience and reveals the essentials of purchasing mahogany furniture for everyone. First of all, look at the legs and feet of the furniture for signs of fading and soaking. In the humid areas in the south, furniture is usually placed directly in the mud, which will happen after a long time. Secondly, see if the patina is natural. Generally, there will be natural patina in the position where the user's hands often contact. The new imitation patina is either unnatural or made in a place that is not often touched. Again, look at the copper live parts. If the copper pieces of old mahogany furniture are original, it will take decades or even hundreds of years to polish by hand. Copper movable parts include face pages, hinges, handles, corners, panels, locks, etc. Some furniture with better materials will be made of white copper, which will give off a faint silver light after a long time, which makes people think. Some copper moving parts have various patterns, such as animals, flowers and auspicious words. And the craft is fine, which is difficult for coppersmith to imitate now. On some patterns with strong folk interest, we can also distinguish the regional customs and the fashion of the times, thus obtaining precious humanistic information. Then, look at the decoration traces. After renovation, some cloth chairs will leave many nail holes in the original chair ring. This kind of chair is old. Some rattan chairs, the original rattan surface rotten, will leave rattan eyes, you can see it when you turn it over. Then, look at the wood grain. Some furniture will have uneven wood grain on the surface, but we should look carefully to see if it is hard rubbed out with a wire brush and whether it is worthy of the original wood grain. Hard-ground wood grain always has an unnatural feeling. Finally, look at the bottom plate and drawer plate of mahogany furniture. Such as old tables and stuffy cabinets. , the bottom plate and drawer board have imitation old gas. There is also matte black paint, but it is absolutely lifeless. Then look at the side panel of the drawer. There should be a chamfer line on the side to avoid hurting your hand. It is also important to look at tenons. The tenon used to be square, and the tenon was locked by a pin. If you see that both ends of the mortise are round, it means that it is machined and must be a new imitation.

Five advantages of editing this paragraph

High-grade solid wood furniture made of mahogany has many advantages after years of historical evolution, mainly including: 1. Is mahogany furniture less ergonomic than ordinary modern furniture? This is a misunderstanding of ordinary people. In fact, after long-term scrutiny and improvement, many mahogany furniture can meet the functional requirements of the human body according to the scale of human function, which is highly scientific. Take the chair as an example, in which the curved back chair and the round back chair meet the needs of the human body and feel comfortable to sit on. Second, elegant mahogany furniture, seeking unity in change, fine carving and smooth lines. There are simple and generous imitation styles, elaborate imitation styles and elegant and generous French styles, which are suitable for different people's aesthetic needs. Third, the structure is rigorous and the workmanship is fine. Mahogany furniture mostly adopts the combination of tenon and mortise, which is ingenious and coincidental, firm and durable, and has a strong scientific nature from the mechanical point of view. Moreover, the traditional mahogany furniture in China is basically completed by craftsmen, and every knife falls with the craftsman's heart. At the same time, we must pay attention to the harmony and unity of the overall art. Fourth, pay attention to the materials used. The real traditional mahogany furniture in China is made of precious hardwood, namely mahogany, with excellent texture, hardness and durability, calm texture, elegant appearance and luster. 5. Value preservation and appreciation integrates practicality, appreciation and value preservation. China traditional mahogany furniture has a long history and high quality, and it is a treasure that Chinese and foreign collectors dream of. In addition, the resources of redwood are limited, and the growth cycle of redwood is very long, some of which can reach hundreds of years. Therefore, mahogany furniture with rare things as the most valuable will have more and more unique charm.

Edit this maintenance method

Mahogany furniture is different from ordinary furniture, which is suitable for humidity and avoids drying. Therefore, mahogany furniture can't be exposed to the sun, and air conditioners can't blow on the furniture. Indoor air should be kept dry in spring, autumn and winter, and it is advisable to spray it with a humidifier. Indoor fish and flowers can also adjust the indoor air humidity. Redwood furniture should be properly hidden, and objects should be stored in the cabinet, not exceeding the door frame. If it is often jammed, the cupboard door will be deformed. The mahogany surface of mahogany furniture is generally brittle, such as desktop and chair surface. Always pay attention to prevent bumping and cracking. If tenons are found in the stressed place during use or moving, they must be glued and sealed again before use. For the panel of Taiwan Province mahogany furniture, in order to protect the paint film from being scratched and show the wood grain, a thick glass plate is generally placed on the countertop, and the glass plate is separated from the wooden countertop with a small suction pad. It is not recommended to use transparent polyethylene crystal disk. Mahogany furniture is generally used for a long time, so it is usually necessary to protect the surface coating of the furniture, and it is best to rub a little wax every three months, which not only increases the beauty of the furniture, but also protects the wood. To keep mahogany furniture clean and tidy, you can wipe the dust with clean gauze every day. Chemical brighteners should not be used to avoid damaging the paint film. In order to keep the paint film of furniture bright, walnuts can be crushed, peeled and polished with three layers of gauze. Prevent alcohol, banana oil and other solvents from being reversed. Otherwise, the furniture surface will leave scars. When the surface of furniture is stained with dirt, it should be cleaned with mild soapy water, waxed after drying, and restored to its original appearance, but it should not be wiped with solvent liquids such as gasoline, kerosene and turpentine, otherwise it will erase the luster of the paint and coating on the surface. Walnut oil used to maintain furniture is only suitable for furniture that has not been painted and waxed. Don't use it too frequently. Usually it can be used once every 2-3 months. In a relatively dry environment, the maintenance interval can be appropriately shortened and maintained once a month or so. But be sure to pay attention to the dosage when using it. Oil has vacuum characteristics. If the dosage is too large, dust will adhere to it, resulting in a greasy feeling.
