(iv) Same practicability

On the walls of the Mogao Grottoes in Dunhuang, China, because there are paintings, they are called murals.

There is a painting on the mountain cliff, which is called a cliff painting.

Engraving (different from carving) a painting on a wooden board is called printmaking.

There are paintings on the cloth, called Chinese paintings, oil paintings, and thangkas.

There is a painting of Tiangong on the natural stone body, which is called the picture stone.

They all get their names because of paintings, so they belong to different art varieties of the same category of painting art.

Murals and cliff paintings, which cannot be moved at will, greatly reduce their practical value, and therefore, are regarded as non-priceable and non-tradable works of art (fraudulent movement or trading is an act of vandalism).

Compared with murals and cliff paintings, the picture stone has advantages and advantages, and has a variety of practical values such as oil paintings, Chinese paintings, prints, etc.: it can not only be moved at will, but also can be put on the shelves to watch, and can also be displayed on the table on a few tables.

(5) Same plasticity

The picture stone has the potential value of humanistic reshaping art, just like the album of humanistic paintings, which is rare.

Taking the picture stone of a single stone and a single painting as an example, if the stone is above Νzun, you can create a series of picture stones with different themes at will.

For example, the Hundred Birds and Phoenixes series, the Hundred Flowers Series, the Hundred Trees Chaoyang Series, the Sunrise Series, the Sunset Red Series, the Sun, the Moon and the Stars Series, etc., are countless.

Each of these series, whether it is a dozen, a dozen, or a hundred, is a painting.

Each painting is not only an independent natural artwork, but also a member of the treasure trove of painting art.

2. Unified unit of measurement

The size of the stone body of the picture stone is generally smaller than that of humanistic paintings such as Chinese paintings or oil paintings. The size and specifications are different, and the price is obviously inappropriate.

The size of the oil painting is measured in square feet according to international practice.

The size of a Chinese painting is measured in square meters.

The size of the stone in the picture is generally measured in metric centimeters.

Whether it is the imperial unit of oil painting or the Chinese unit of Chinese painting, it can be converted into a metric unit with centimeters as a unified standard.

Humanistic paintings, with the price of centimeters as the unit of measurement, the same or similar to the picture stone and its picture effect of humanistic paintings, this price and the other price also have practical significance.

Suppose it is known that the standard price of the square foot of the painting works of the Ming Dynasty painter Tang Yin is 33 or 30,000 yuan. Knowing that the size of the "Lady Picture" painted by Lei Tong Tang Yin is N square centimeters, you can directly calculate the price of the picture effect of the picture stone.

If the owner of the picture stone finds a humanistic painting work, but does not know the standard price of the painter's work in square feet, but only knows the unit price and size of the painting, or knows the length and width of the painting, he can also calculate the price of square centimeters, and then he can pay this price and the other price.

In Chinese painting, there are paintings and artworks with fans and albums, which are generally not priced in square feet. Its size is comparable to the specifications of the picture stone, once there is a price, the picture effect on the picture stone is similar, and the price can be directly this and the other.

The size of the album in Chinese painting is generally 19cm×31cm, and the size of the fan is generally 17cm×49cm.

Among them, there are also large or small ones, but the difference is 1-3cm.

In 2005, the album of 100 flowers and birds by Ming Dynasty painter Chen Hongshou was sold at auction for 28.6 million yuan;

In the same year, the auction price of the album of 100 open landscapes by modern painter Lu Yanshao was 69.3 million yuan;

In the same year, the Qing Dynasty painter Wu Li's 12-karat landscape album was sold for 26.83 million yuan, which is a rare reference work.

3. Uniform size representation

The size of the picture is a prerequisite for the valuation work, so it is also very important to unify the size of the picture stone.

First of all, it is recommended to use the mathematical area formula to express the size of the picture stone. That is: area = length × width.

Second, the size of the picture stone must be represented by the positioning consciousness of "length, × and width", that is, the numerical representation of "length, × and width", which must be positioned, that is, it must not be written as "wide × long".

Otherwise, editors and readers of news outlets will not be able to accurately figure out which is "long" and which is "wide" from the two numbers multiplied together.

Third, in order to explain the thickness of the stone to the reader, the size can be separately indicated, that is, the thickness of the stone: ××cm.

It must not be written as a mathematical formula (?×?×?) multiplying three numbers, so as not to mistake the reader for the artistic effect of the three-dimensional modeling stone represented by the "volume formula".

Fourth, pick the best and increase the price

The overall image of each picture stone is composed of eight natural conditions, including natural, picture effect, stone shape, stone quality, painting position, color difference, stone surface, and size, which is also called the eight natural expressions and eight value structures of the picture stone itself.

Among them, the picture effect has been priced according to the price of the same or similar humanistic painting works mentioned above in this article, that is, it has already been priced.

The other seven forms of expression, if implemented into the comparison between each picture stone, are somewhat different.

Among them, the excellent ones should increase the price, and the poor ones should not increase the price, should the price be reduced?

Because, the discussion is how to price the picture stone, that is, to unify the project, decompose according to the item, pick the best and increase the price, if the price is not increased, it will be regarded as a price reduction.

If the price of the "bad item" of the picture stone is not increased, but the price is reduced, where does the price reduction come from? Is it from the price of the picture effect? Or is it from the price of other excellent projects? If it is reduced, it should be unreasonable!

Among the seven natural value structures other than the picture stone picture effect:

natural

All picture stones are natural works of art, and "natural" should not be used as a condition for price increases.

However, some of the picture stones sold on the market are made of plastic surgery, some are chemically or artistically processed, and the beauty of the natural picture stones is decorated so that they are neither artificial works of art nor natural works of art, which is nondescript.

Therefore, I had to take the "natural" thematic item as a condition for the price increase, as long as there are no artificial traces of the picture, the price can be increased (polishing the type of picture stone, the picture must also be natural).

Otherwise, not only will the price not be increased, but it will not be included in the price of the picture stone!

Stony

The hardness of the stone is about 7 degrees on the Mohs scale, and the dense and delicate one is the best stone quality, and the price is increased.

For example, basalt, siliceous quartzite, etc.;

Similar to sandstone in sedimentary rocks, phyllite, gneiss in metamorphic rocks, etc., if the texture is rough, the hardness is uneven, and the structure is not dense, the price is not increased or reduced.

Stone shapes and painting positions

The stone shape and the painting position are two forms of artistic expression that complement each other.

If the stone shape is good, the painting position is not good, and the practical meaning of the stone shape is also lost.

Because, the picture stone is the highlight of the picture effect as the main scene and the real place of the value, only the picture is good, the stone shape is good, it is really good, and the price can be increased.

If the stone shape is good, the painting position is not good, and the practical significance of the stone shape is lost, and the price must not be increased.

Stone face

Stone surface refers to the overall surface of the picture stone.

After natural grinding of the flat and smooth stone surface as well, the price is increased.

Splitting stones, which have not been naturally sharpened, are the worst stone surfaces and do not increase the price.

For example, if the stone surface resembles watermelon skin, it is better, and the price will be increased, and if the stone surface resembles pineapple skin and cantaloupe skin, it will be worse, and the price will not be increased.

However, the stone surface is as if it were its physical appearance.

For example, if the stone surface of the painting is as pitted as the surface of the walnut shell, it is a strange picture stone, which is the best stone surface, and the price will be increased.
