Our Tibetan stone appreciation is also a tradition, of course, it should be in line with the aesthetics of our excellent traditional national folk culture, not only Tibetan stone.

Stone culture is a comprehensive form of artistic expression, of course, we need to learn more knowledge to enrich the stone culture itself, which can better promote the development of stone culture, we have the responsibility to dedicate to it!

I carefully looked at Mr. Peng Zhongyong's feng shui layout, and compared the results of his random placement of strange stones, I didn't feel ashamed.

Let's just say that the Nine Dragons Bima Stone, the horse's head is facing inward, how can it take off.

Sometimes, playing with stones is like this, if you are not particular, it is easy to show the horse's feet, and you can see how well you play with stones.

The directories listed by Kowloon are basically all now complete, what else has not been considered?

Yes, now the strange stone fraud is serious, and it is inevitable that there will be fraud in Jiulongbi, so it is necessary to list a special chapter on how to identify the fake stone of the picture stone.

Kowloon checked the relevant information, combined with his own experience of appreciating stones, and sorted out some common methods of counterfeiting picture stones.

One of the means of counterfeiting strange stones

Strange stone paintings

Strange stone painting, unprocessed gravel or pebbles, the use of rock has a certain permeability, with chemical dyes directly dyed, this kind of simple, almost pebbles can be universal, the stone is coarse is easier to color, in order to paint to make up for the shortcomings of the original stone.

It is divided into several categories:

1. Direct painting method, paint with pigments with fixing agents, and then coat varnish to prevent fading, with a wide range of contents, mostly dragons, tigers, portraits of leaders, zodiac signs, and realistic images. This kind of color stone and other plane patterns appear more, because the pattern is not easy to imitate nature, most of them are too similar, on the whole it is still relatively easy to see, easier to identify, not too lethal.

For those stones without varnish treatment, the picture can be faded with a fading agent, the color can be lightened by strong cleaning with a detergent, and the color can be worn off and the base color can be exposed by light grinding on the rough stone.

However, for the stone treated with varnish, most people are reluctant to scrape off the varnish layer, so they buy the processed stone without knowing it.

2. Supplementary painting: Draw part of the original color, and keep the original color, it is difficult to find if you don't pay attention.

This kind of stone appears more in plane patterns such as Xiuyu jade tree stone, marble, and multicolored stone.

This type of painting on top of the pattern of the rough stone makes this method of counterfeiting even more confusing.

Sun, moon or animal patterns can often be seen on the surface of river pebbles.

3. Partial painting on natural stone.

It is common to add eyes, mouths, noses, whiskers and the like to animal figures, and add sun, moon, and flowers to landscape paintings, and paint them with paint, which can generally be wiped off with fading agents or strong cleaning.

4. Make text stones.

This category is also based on natural textures, on the basis of which strokes are depicted and modified or added to make it into text.

The strokes and words of this processing are rather stiff or too perfect, and often numbers form a word or phrase.

5. There is another method that is quite clever, and it must have been invented by a person who understands chemistry - rust.

The rust method is to use the reddish-brown color of rust and the fixative to make a simulated image, which has a special sense of vicissitudes and room for flickering.

The second method of counterfeiting strange stones

Chemical fading

The chemical fading method is mainly used in the appropriate parts of the homogeneous rock, usually with strong acids and strong alkalis to remove the color of the relevant metal ions, and the stone color is faded to create a picture content that needs to be patterned.

Most of the stones that can be chemically faded are fine sandstone that can be easily discolored.

Chemical fading has produced a lot of sun and moon stones, which have been flooded.

But the patterns made with this method, often the edges are blurred, and some can vaguely see the original colors and textures, and now most of them are easy to identify, so the number is also less, and what can be seen in individual posts "Dragon", "Phoenix" and other mascots.

Typical manufacturing processes are as follows:

1. Dark rock fading: first determine the rock properties, generally choose dark rocks with uniform hues (sandstone and limestone in sedimentary rocks), and then design graphics, such as dragons, horses, pigs, etc., and then use a solution with corrosiveness and the ability to complex metal ions to make the rock in the graphic part fade to a light to white effect.

Luoyang's sun stone moon stone, many of the bright "sun" and "moon" on it are burned with chemical reagents.

2. Oxalic acid iron removal method: This is a method that can eliminate rust by using oxalic acid and other mixtures, and the counterfeit can be identified from obvious rust traces.

Oxalic acid, dilute hydrochloric acid and other acidic solutions can be used to remove rust or fade rust

3. Filter paper dipping method: simple and easy, the effect is the same.

The so-called filter paper is the absorbent paper commonly used for filtration in laboratory testing, and the effect of three layers is better.

Cut the filter paper into the shape you need, but unfortunately most people cut it into a dragon and phoenix or something, and you can see it at a glance.

Then stick the three-layer filter paper on the appropriate position of the stone, and use the brush to stick the concentrated acid to drop onto the paper you cut, so that the paper is soaked, in order to achieve the desired effect, the acid can be replenished once after the paper is dry, and it will be made after 24 hours.

The third method of counterfeiting strange stones

Barbecue, smoked, soaked

Barbecue smoked natural strange stone is on the stone surface with an inert substance to paste the pattern, and then the stone is smoked with fireworks, steamed with water and fire, to achieve the purpose of artificial coloring treatment, this kind of stone to modeling stone and picture stone for more, and looks particularly vivid and perfect, lifelike, is its disadvantages.

The methods are also varied:

1) Dipping with medicinal solution: Counterfeiters use similar batik skills, first apply a layer of wax on the surface of the stone to set aside for painting, and then use chemicals to wash off the wax, and a piece of "picture stone" with a similar pattern or font will be deceived by people at a high price.

2) Wet cloth smoking: use the wet cloth with a cut pattern first and stick it on the soft stone, and the place that is not pasted with a wet cloth should be dyed with color, so that it can be eaten after heating, and then it can be heated and smoked.

3) Asphalt cooking: choose smooth and flat pebbles, draw the required figures with wax on the stone surface, and then put the painted stones in the asphalt and boil them for 30 minutes, take out the boiled stones and cool them naturally, and then peel them off, so as to show the wax painted figures, and the color will be deepened where there is no wax painting, generally light black or dark yellow. This kind of processing method has a strong contrast of color difference, leaving both patterns and flaws.

4) Paraffin soft dipping: The method is similar, paraffin wax is smeared, only the color needs to be soaked, the contrast of the picture can be determined according to the soaking time, and the pattern of the picture can be determined according to the shape of the stone, so it is more flexible.

5) Coloring and steaming: This is simple, dye the stone surface with color, leave the desired pattern, and heat and steam, which can only be steamed, not boiled or baked.
