My system is not decent

Chapter 983
After looking around, Chen Wenzhe felt happy when he saw Lie Xin, his hands itched a little.

Of course, he will not do simple glazing, that is, removing light and coating, which do not have much technical content.

When he saw a blue-and-white plate with cloud and dragon patterns that was used as a specimen for teaching, he thought that there is only one way for this kind of thing to appear here, and that is sea fishing porcelain.

Therefore, when Chen Wenzhe saw this large plate, the first thing Chen Wenzhe thought of was to make rust.

Making water rust can not only be used on salvaged porcelain, but also on ancient porcelain.

If it didn't fall into the water, there is very little water rust on the porcelain after Ming and Qing Dynasties. The main target of water rust is the unearthed ceramics from this age.

There are many methods, but Chen Wenzhe has never done it before.

For example, the spreading method, which is to use a brush to dip an appropriate amount of diluted nitro varnish, and apply a thin layer on the parts that need to be rusted.

If the water rust appears to be sagging, the material liquid can be saturated to form a mark.

When it is not dry, spread talcum powder or other body pigment powder on it, and after drying, just remove the floating powder.

These methods all use more or less chemical raw materials, and there are many methods, and there is another method that is more effective and can also get rid of soil rust at the same time, that is, the double decomposition method.

Apply a layer of sodium silicate aqueous solution on the parts that need to be rusted, and brush the surface of the coating with 5% dilute hydrochloric acid after the coating is dry.

When hydrochloric acid meets sodium silicate, a double decomposition reaction will occur to produce white salt substances.

Afterwards, rinse the rusted part with clean water to remove unreacted chemicals and excess salt.

When doing water rust, you can also add other pigments appropriately, or sprinkle a little loess, and do it at the same time as the rust.

Of course, although it looks similar on the surface, you can tell the authenticity by scraping it with a knife.

However, a piece of porcelain looks mottled, with rust and rust on it. Who would scrape it with a knife?
What I just said is relatively simple, especially to make soil rust, there are more methods.

The simplest method is the soil burial method. The imitation pottery is buried in loess rich in groundwater. After being buried for several months, it is taken out to dry and repeated several times to form soil rust.

The effect is especially good if buried in the old site of ancient pottery firing or in ancient tombs.

The disadvantage of this method is that the soil rust is not formed in a short period of time, and it is not tightly combined with the pottery. It will fall off when it is lightly scraped with a fingernail or a knife blade, but this phenomenon will never occur in real soil rust.

A slightly troublesome way to make soil rust is the heating method.

Heat the pottery, and then mix the soil from the old pottery sites or tombs with alum and apply it repeatedly while it is hot.

This goes on and on until the color is the same as unearthed.

This method also has the disadvantage of not being tightly bonded. In addition, if it is washed with alkaline boiling water, the rust will all fall off.

Then there is the mud method, which is more powerful, and there are secret recipes in it.

To put it simply, put the soil in a special Chinese medicine, boil it for 20 hours, and then apply the obtained mud on the surface of the ceramic.

The soil rust treated in this way is very similar to the unearthed soil rust, and it is closely combined with the ceramic, even if it is scraped with a sharp blade, it is not easy to fall off.

In addition to this method, there are several methods of soil rusting, all of which are relatively simple, but each has its own disadvantages.

Like the clay method, first mix ceramic glass glue and soil into a viscous shape, apply it on the surface of the ceramic, and then heat and beat the burning newspaper on the surface of the ceramic.

The rust produced is closely combined with the pottery, and the black paper ash will penetrate deep into the soil, making the traces of time even more apparent.

Because of the existence of glass glue, it will emit the smell of glass glue burning when encountering high temperature.

The coloring method is to apply shellac paint twice on the surface of the pottery, then mix the mineral pigment with the shellac paint, soak the pottery to make the base color, and then apply bletilla striata juice on the surface to make soil rust.

Once the pottery made by this method is put into hot water, the traces of forgery can be seen at a glance.

As for repairers and splicers, the soil rust at the joints will not condense with the original, and it is not difficult to see through it after careful identification.

Chen Wenzhe first learned how to make old things and how to do them.

When you see a cultural relic, you only need to study it to see if there are any signs of aging, and you will know whether it is real or not.

Of course, the most powerful technique for making old things is clam light.

This kind of thing is Baoguang, and it looks really beautiful when it is done.

Without this layer of clam light, porcelain looks nothing like it.

But making "clam light" is not so simple.

If you have money and conditions, it is relatively easy to make clam light. For example, you can use advanced vacuum coating method to make "clam light".

This method is similar to the metal coating on the lens of optical glasses.

As long as two metals with different properties are alternately plated on the glaze, when the coating reaches a certain thickness, a beautiful "clam light" will appear.

Or use "electro-optical water" to make "clam light", which is simpler and easier than the vacuum coating method.

Because the resistance value of artificial "clam light" is different from that of natural "clam light", it can be identified by using a surface resistance instrument.

Under the guidance of Chen Wenzhe, the ceramics factory soon got on the right track, and many works were produced every day.

Among them, the best ones are teapots, tea pots, plates, dishes, etc. Among them, large plates and porcelain vases are the most produced.

The large plate is mainly different in decoration, and various decorations are generally full of works.

As for porcelain vases, there are more, such as vases, vases, gourd vases, etc., all of which are produced in South Vietnam, and Chen Wenzhe can be regarded as doing as the Romans do.

It's just that there are not many porcelain-making machines in Chen Wenzhe's factory, almost all of them are made by hand, so in the market here, they are considered high-end products.

In addition, the fired porcelain also needs to go through an antique process, commonly known as old-fashioned, so that the price of antique porcelain products will be more expensive.

Now South Vietnam's economy is developing well, and the antique market is also booming driven by foreign tourists.

Chen Wenzhe got the ceramics factory and played an important role in it.

No matter where the antique market is, where can there be fewer fakes?
Selling antique porcelain honestly is the art of selling.

To be dishonest and to sell it as an antique is to deceive people by being old.

Anyway, Chen Wenzhe's products are all antique porcelain, with clearly marked prices, and no deception.

As for how to deal with being taken away, he doesn't care.

It is based on this concept that the works of his ceramic factory caused a great sensation as soon as they appeared on the market.

The difference between new porcelain and antique porcelain can be seen by anyone.

Therefore, as soon as Chen Wenzhe's factory opened, the business was booming.

There are quite a few people who know how to make porcelain in South Vietnam, and even many factories have grown bigger.

But as old as they are, they are really brothers.
