This chemical coating is bright, bright and smooth, and has a slight graininess. This kind of paint is rough to the touch, easy to crack and has the shortest service life. Mostly used for inferior practice piano. )
Synthetic paint (waist drum paint) is smooth, rich and flat! Look carefully at the traces left by the painting.
Traditional lacquer (Chinese lacquer, also called raw lacquer) is tough, smooth and textured! Look carefully at the traces left by the painting. (Maximum service life)
Grey tire
Pilose antler paste, babao ash and tile ash are the main materials.
Velvet antler paste and babao ash are the best, followed by tile ash.
Now, in order to make the old look good, and for beginners to see clearly, sometimes the lacquer tires of guqin are worn off to reveal some gray tires, and the antler cream is golden in color, so it is not necessary to elaborate on the eight-treasure ash. If the gray tires are all tile gray, it won't work.
The floor material of guqin is invisible, and we can only look at the material of its panel carefully from the Phoenix Pool behind guqin. But now many people use fire to smoke the sound, which increases the difficulty of identification. Wipe the imprint with black charcoal by hand.
1, paulownia
2. Paulownia: the material color is light white, which can be completed in three to five years. The wood is very loose. If you pinch it gently, the nail will go in. However, experienced piano players will choose paulownia wood with a long tree age and choose tree segments with appropriate density, which is also a good material for making pianos.
3. White paulownia: a good material for making pianos recorded in many ancient documents.
4 Chair Tung: As early as the Book of Songs, it was recorded: "Chair Tung paint, cutting Qin Sang"; It is a good material for traditional piano making.
5. Paulownia wood has light color, fine wood and good toughness. Long-standing trees with natural weathering time above 100 years are better materials for piano making. /kloc-the new paulownia wood within 0/00 years is not suitable for making a piano, and the timbre cannot be revealed.
6. Chinese fir
New shirt wood-old shirt wood (old house beam)
The wood of the new shirt is white, and as time goes on, the color of the wood becomes more and more yellow. Jin Maomu is the oldest and has a strong fragrance.
Han Mu pointed out that the coffin board of Han Dynasty, which has been dull and loose for more than 1000 years, is a good material for Qin.
At present, some manufacturers make guqin panels by splicing some small specifications of wood. These guqin panels are ugly in appearance, but it doesn't matter whether they are spliced or not as long as the workmanship and timbre are good.
The floor of Guqin mostly uses hard wood such as Catalpa bungeana, Toona sinensis and rosewood, and also uses the same wood as the panel. This kind of piano is called "pure yang material", and it should be reasonably matched according to the vibration of the piano material!
In a word, the most important thing to make a good piano is the player's experience and technical level, and the decisive factor is the structure of the piano groove and the treatment of the lacquer tire, otherwise a piano with good timbre can't be made with the best wood.
