My system is not decent

Among high ancient porcelains, such as Ru Kiln, Guan Kiln, Ge Kiln, and Jun Kiln are more difficult to imitate, but other ordinary porcelains are not difficult to imitate.

And as long as it is imitated, it is easy to make it old.

Especially combined with the hand-grinding method, the Gaogu porcelain that Chen Wenzhe is making now is even more similar.

The hand-grinding method is very simple and can consume time and energy. It only needs to grind the porcelain with sweaty hands for several months after it comes out of the kiln until the dazzling "fire" is eliminated.

To put it simply, it is extremely simple, but it requires patience, time-consuming and labor-intensive work, and it must be careful and thoughtful, which is rare now.

The simple method is to use the water grinding method, that is, place the utensils under the continuous flowing water, rub the glaze surface with the flowing water, and eliminate the "fire".

If you want to invest some capital, use the oil grinding method.

First rub it lightly with a pulp mound, and then rub it with a kraft rubber rudder dipped in oil to eliminate fine marks and make the glaze smooth and moist.

In fact, no matter how these techniques are used to polish porcelain, another technique is used, which is mirror grinding.

This is Chen Wenzhe's unique skill, so when he learns other skills, it will be very easy.

But other people can't do it, they need to practice slowly.

And being able to practice is also a kind of happiness.

For example, the South Vietnamese workers in the factory now have no technical content in what they do. .

For example, the chemical corrosion method is used to make the old. At the beginning, Chen Wenzhe used this method to deceive the little devils, and only then did he get his first pot of gold.

Chemical corrosion method is also a more commonly used method, which is divided into acid leaching method, mixed leaching method and oxidation method.

Because the glaze of the ceramic is silicate, it forms a transparent glass-like glaze with a beautiful luster.

Therefore, soaking porcelain with acetic acid, hydrofluoric acid, nitric acid, oxalic acid, etc., which can react with silicates, can cause glaze corrosion, make the glaze dull, and appear turbid, thereby eliminating the "fire".

Some do not soak, and directly wipe the glaze surface repeatedly with a rag dipped in acid, which can also achieve the effect.

The disadvantage of this method is that the acid corrodes the glaze surface too strongly, making the glaze color devitrified, the luster is too dim, and even milky.

The effect produced in this way is very different from the "clam light" that is naturally formed over the years.

Under a high-power magnifying glass, countless small holes that have been corroded by acid can be seen, so it is relatively easy to identify.

However, sometimes in order to pursue speed and profit, and the processed works are not very good, naturally there is no need to bother.

If you want better results, you have to find a way.

In this way, the mixed immersion method came into being.

The mixed leaching method is to mix several solutions together for use, such as leaching with acetic acid and then using tea water, plant ash water, etc.

This will not only eliminate the "flare", but also make various stains, which makes people mistakenly think that it is caused by long-term use.

Glazed pottery and porcelain with high water absorption rate, after acetic acid treatment, the residue is easily absorbed by the carcass.

And after doing this, washing the surface of the utensils with hot water will give off a bitter smell.

For Chen Wenzhe to do it, he must not use these obviously flawed chemicals, but a door-blocking formula, which cannot be easily taught.

Of course, most of the porcelain produced by this ceramic factory is produced by local craftsmen in South Vietnam. This kind of porcelain of your level does not need very good old-fashioned methods.

There are many ways to simply process porcelain, the easier one, the method that maximizes the benefits, is the sure oxidation method.

This is to use the strong oxidant potassium permanganate to oxidize the glaze surface. Except that the surface is slightly red, the rest of the features are consistent with those after the acid leaching method.

Rinse the utensils with water. If potassium permanganate is used too much, the water will turn purple.

Sometimes if you touch some water with your fingers, your fingers will also be dyed purple-brown.

However, after this treatment, if some unique chemical reagents are used, the effect will be better.

For example, the carcass can also achieve an old-fashioned effect through this mixed infiltration method.

Of course, Chen Wenzhe would definitely not spread this method.

He is just step by step, constantly strengthening the technique. The result of this is that if you want to get a perfect antique porcelain, you need to use different techniques and continuously process it, which is very labor-intensive.

If you don't hesitate to spend effort and do something seriously, it is also very particular.

It's just that people nowadays are more eager for quick success, even Chen Wenzhe is no exception, so some stupid methods he knows have never been used.

Of course, it can also be taught here as a secret technique, anyway, Chen Wenzhe himself doesn't need it.

There are various ways to make old, in addition to chemical corrosion, grinding and polishing, as well as smearing oil stains, soil burial and high-pressure cooking.

The method of smearing oil stains is to dip the oil stains in the range hood in the kitchen with a sponge and apply them to the ceramic surface.

Wipe it off after an hour, and repeat the operation several times to make the ceramic glaze matte, and there are no traces of wear. This method is very cheap.

The matting agent matting method is to add a certain proportion of zinc oxide, zirconia and other matting agents to the configured glaze, which can achieve twice the result with half the effort.

Of course, these old-fashioned methods can be identified, just like porcelain with a matting agent, using energy dispersive X-ray fluorescence analysis, as long as the content of some metal oxides in the glaze of the utensils is found to exceed the normal value, it can be concluded that it is modern. Imitation.

These are relatively simple to say, but you must have a skeptical eye before you can use the most aggressive method to identify the authenticity of a piece of porcelain.

If you don't understand anything, no matter how simple these old methods are, you can't identify anything.

Therefore, don't look at the simplicity of some old-fashioned methods, and ordinary people will really be deceived.

With such a simple method, Chen Wenzhe knew too much.

For example, the soil burial method is to bury new porcelain in fine mud, take it out after a few days and wipe it off with a dry cloth. After going back and forth several times, you can see that the glaze has a yellowish old color.

High-pressure cooking is to use tea and a little alkali to cook the porcelain for a long time to remove the floating light.

In recent years, new imitations have been steamed in a pressure cooker, which can also achieve the purpose of making the glaze lose its luster.

The internal system of the bead that Chen Wenzhe got is a civilization inheritance system, which is mainly used to inherit civilization.

But Chen Wenzhe has never passed it on properly once. In the future, he plans to pass on all these skills slowly.

It is absolutely impossible for porcelain making to be passed on to the South Vietnamese. Chen Wenzhe does not intend to pass high imitation porcelain, that is, antique porcelain, to the South Vietnamese, but old-fashioned porcelain can be passed on.

Now it is only passed on to the Chinese people. After working in this factory for a long time, those South Vietnamese workers will naturally learn it.

As for what to do after learning, he can't control it, and he can't control it.

Of course, the old-fashioned techniques passed on must be basic things, such as some secret techniques, Chen Wenzhe would definitely not be able to pass them on easily.
