The price and function of raw lacquer technology in making raw lacquer

Raw lacquer (natural lacquer), commonly known as "earth lacquer", is also called "national lacquer" or "raw lacquer". This is a milky white colloidal liquid cut from lacquer tree. Once exposed to the air, it will turn brown, and after a few hours, the surface will dry and harden, forming patent leather. Natural raw lacquer has many excellent characteristics, so it is widely used. It can be used as an important coating for military, chemical, textile, light industry, shipbuilding, electromechanical and craft products. So, do you know the craft of lacquerware? What about the price and function of raw lacquer? Next, I will introduce the raw lacquer technology in detail. If you are interested in this aspect, let's learn about it together!

Brief introduction of raw lacquer

Raw lacquer is also called natural lacquer. Generally called Chinese lacquer. It is a kind of natural resin coating, which is a white viscous emulsion that flows from the bast after the bark of Rhus verniciflua is cut and processed. Rhus verniciflua is a deciduous tree with a height of 20 meters. Leaves ovate, ovoid or ovate-lanceolate. Yellow-green flowers in early summer, oblate fruit in autumn, smooth and yellow in appearance. Lacquer trees that have grown for 5-8 years can be cut with lacquer liquid. As early as the Shang Dynasty in China (about17th century BC to1th century BC), exquisite lacquerware was made of large lacquer. The scientific reason is that laccase in lacquer can accelerate the oxidation of urushiol to form a film, and it is a natural drier for curing and forming a film of raw lacquer coating. This drying effect is related to the activity of laccase, and the activity of laccase determines the drying speed of raw lacquer coating.

The role of raw lacquer

Raw lacquer is used to brush furniture and other production and daily necessities. With the popularization of various paints and lacquerware, raw lacquer gradually disappears in people's lives, and the art of "carving lacquer" is also in danger of disappearing. Lacquer carving is a dirty and tiring job, and not everyone can touch raw lacquer, so not many people can really engage in lacquer carving skills. The skill of cutting paint seems simple, but in fact it is very particular.

After the lacquer tree is obliquely cut with a crescent-shaped mouth, the raw lacquer will flow out along the edge of the cut. Paint shears usually use hard leaves about 10 cm long, and then fold them in half to form a small container, which is inserted under the opening to let the original paint slowly flow into the leaves, and the paint can be collected after one or two hours. On a tree, you can cut the paint every 80 cm or so. The wound can be cut once a week, adding a little at a time. Cutting once a year can cut about 20 times. After three to five years, the incision will be closed again. The paint cutting season is usually from June to September.

Characteristics of raw lacquer

Raw lacquer is the most traditional natural lacquer in China, and its main component is cyanine. When the paint juice is brushed on the surface of an object, it can be dried in the air to form a primary color hard film, which is tough and durable and can resist the corrosion of various chemicals.

Raw lacquer has a wide range of uses, which can be used to make cooked lacquer, varnish and various colored paints. The technical application of raw lacquer began thousands of years ago, and it is even more popular today. Because of its toughness and luster, lacquer wax has unique durability, wear resistance, heat resistance, oil resistance, water resistance, corrosion resistance and excellent electrical insulation. China raw lacquer occupies an important position in modern mahogany furniture. Make mahogany craft furniture even more icing on the cake.

Raw lacquer technology

The painting process is very strict with the material of the furniture itself. Usually choose materials with hard texture, beautiful wood color, clear lines, no damage and scars, and the color difference should not be too large. Commonly used wood is rosewood, Huang Huali, ebony and old mahogany. Cork can't be used When painting, apply natural paint (national paint) without any pigment on the surface of furniture. When the paint is wet, wipe off the surface paint film with gauze, which can make the paint surface dry and dull, and at the same time present the natural color of wood. Painting needs to be done many times, each time it is very thin, and so on and so on until the paint film reaches a certain thickness requirement. After the paint is completely dry, it should be polished. Paint polishing is very particular. Traditional grinding does not use sand skin, but uses a forage, which is a fern called "Cao Jie", also called "wood is grass". When in use, fine grass is selected and woven into a straw mat shape, which is first dry-milled and then water-milled to remove the floating light of the paint film and introduce the inherent elegance, so that the paint surface is as bright as jade.

Painted furniture, mainly monochrome furniture, multi-color furniture has also been found. This kind of lacquer furniture, commonly known as lacquer furniture, is unique in the field of ancient furniture. Lacquered furniture should give consideration to the expressive force of wood grain, and the wood grain should appear under transparent paint, so painted furniture has texture requirements for furniture and wood. The most common lacquer furniture in the north is elm, while the lacquer furniture in the south is mahogany, with different materials and different techniques. The last process of making furniture with old mahogany is the same as rosewood-waxing, and never use the method of ordinary rosewood-painting Because old mahogany is full of wax, it can be smooth and lubricated by rubbing wax, and its luster is lasting, giving people a pure and implicit aesthetic feeling. If modern painting technology is adopted, it only covers up the excellent properties of its wood. Moreover, the old mahogany is easily mixed with other mahogany wood by some manufacturers after paint treatment, which provides convenience for them to fish in troubled waters.

Folk lacquer furniture is mainly monochrome furniture, commonly known as "big lacquer furniture", which is different from the lacquer technology that appeared after the late Qing Dynasty. The purpose of lacquer furniture is to express the aesthetic feeling of lacquer, completely giving up the expressive force of wood, while for lacquer furniture, the expressive force of wood grain should be taken into account, and the wood grain can be reproduced on the transparent lacquer surface. Both have their own advantages and are amazing, and they are sought after by collectors. After hundreds of years of use, painted furniture has broken lines, which is particularly beautiful and is the object pursued by collectors. For a long time in the past, we did not study and pay attention to painted furniture, especially painted furniture, which made many painted furniture works flow abroad.
