Modern imitation of Yuan blue and white, the glaze color is mainly for the third kind of Privy glaze, this kind of imitation can be seen in Jingzhen.
However, it cannot achieve the essence of the Yuan Dynasty. Its manifestations are: first, the fluidity of the glaze is too strong, resulting in the glaze layer being too thin.
The second is that the glossiness is too strong, and the third is that the color is unnatural upon closer inspection.
The characteristics of Yuan blue and white porcelain in these three aspects are all unique, which can be used as the most important basis for us to understand the characteristics of Yuan blue and white porcelain, and it is also its rigid point without loopholes.
If you have mastered the above three aspects, you will actually have a good idea of Yuan blue and white porcelain.
Especially in practice, we must first look at these three characteristics, and then look at other characteristics.
For example, flint red, painting style, shape, bubbles, etc.
Of course, theoretically speaking, as long as you look at one thing correctly, it is right.
For example, if it is indeed Suma Liqing pigment, then this piece of porcelain must attract great attention, because ancient pigments do not exist in modern times.
Otherwise, you just don’t understand. Don’t jump to conclusions easily when you don’t understand.
Technology is advancing, and modern people's imitation craftsmanship, driven by money, is progressing rapidly.
Let’s not talk about others, let’s talk about Chen Wenzhe. Now without the motivation of money, he is also racking his brains to imitate Yuan Qinghua.
There is a view in the modern antique shop that as long as you can think of defects, or as long as there are clear characteristics of ancient famous kiln porcelain, modern people will one day imitate it, and it will not take too long.
Even if it cannot be imitated using ancient techniques, modern techniques can certainly be used to achieve the same effect.
Also, although the unique characteristics of Yuan blue and white porcelain cannot be imitated, not all of these characteristics can be fully expressed in every artifact.
Due to differences in production and kiln mouths at that time, there are differences between Yuan blue and white porcelain.
The characteristics of some artifacts are fully expressed.
Some utensils are weak in performance.
If the performance is sufficient, the enamel, pigment, soil, painting, modeling, etc. will all be satisfactory.
Those who show insufficient performance often lack certain characteristics and are puzzling.
However, you can't always say that this kind of antique that lacks some unique characteristics is not Yuan blue and white.
For example: the agglomeration spots are not obvious, the beading phenomenon is not obvious, the flint red phenomenon is not obvious, the makang soil tire is not obvious, the hand-made tire is not obvious, etc.
Of course, some Yuan blue and white flowers are misunderstood because they use domestic materials or returned green materials.
Generally, their characteristics are not well understood, so that these porcelains with insufficient performance cannot be confirmed in time, or even receive a cold reception.
However, the genuine product is the genuine product. As the understanding of Yuan Qinghua deepens, various kinds of Yuan Qinghua gradually appear.
At this time, it is no longer as difficult to imitate Yuan blue and white flowers as before.
However, it is still very difficult to imitate high-quality Yuan blue and white. Unless you are a master antique craftsman, it is still difficult to successfully imitate.
Modern people can always successfully imitate antique porcelain if they invest a relatively large amount of money or if the state takes the lead, and Yuan blue and white is no exception.
But when he came to Chen Wenzhe, he only considered the essence and did not consider making things old.
If old age is included, then he needs to study more.
The production of a piece of antique porcelain, such as the blue and white hair color, painting, pattern, shape, signature, flint red, etc., is quite similar to the old porcelain, and it is almost like the real thing. In addition to making it according to the ancient porcelain when firing, it also needs to complete many other aspects.
Fewer steps.
The first is wear and tear. As long as there is porcelain in the world, there is no porcelain that is not worn. No matter how well protected it is, there will be scratches and wear over time. This is a unique characteristic given by time.
Of course, Chen Wenzhe does not need to make it old, so he does not need to deliberately wear a new imitation porcelain into an old one.
However, the old part is also a stumbling block for imitating Yuan blue and white.
Like wear and tear, naturally it is not used.
Of course, if you really want to do it, use a fine grinding wheel to smooth out the rough areas.
It is mainly about the bottom of the tire. At the same time, place the porcelain on the ground and roll it back and forth, and gently tap it with a hard tool to break out the cracks.
If necessary, you can also use a glass cutter to score chicken claw patterns on the inside and outside of the bottle.
The antique porcelain produced in this way is more like the real Yuan blue and white.
If it reaches this level, it is inevitable to make the glaze surface old.
For example, when peeling off glaze, it is best to peel off the glaze on the edge. Use the tip of the assorted file to pry out a gap first, and then continue to extend it.
In addition, some other features need to be done well, such as modern imitation flint red.
Although not all Yuan blue and white flowers have flint red, most of the truly high-quality Yuan blue and white flowers have flint red.
Therefore, if you want to imitate Yuan blue and white, you must burn flint red.
The second is the problem of bubbles. During firing, you need to use a sharp tool to pop the large bubbles on the glaze surface.
Generally speaking, the glaze layer on the bottom of the utensil is thicker and easier to handle.
There are wear, peeling, and flint red, and the bubbles are also consistent with the characteristics of Yuan blue and white.
It is relatively simple to make it distressed, that is, removing the flames and other processes.
If you are not afraid of trouble, you can mix half and half hydrofluoric acid with water and use a brush to evenly apply it to the surface of the object.
Brush from bottom to top. Where the glaze layer is thick, the painting time can be longer, and where the glaze layer is thin, the painting time can be shorter.
Generally, after half a minute to about a minute of painting, rinse it with water immediately to prevent the glaze surface from being too corroded and dull if the time is too long.
If it feels too bright, apply some salad oil on the surface to make it as moist as jade.
Modern imitation of Yuan blue and white still requires coloring.
The purpose is to give people the feeling that it is worn out and that if anything is dirty, it has gone into the cracks of the porcelain.
Use potassium permanganate solution, mixed with a little brown sugar, and apply it all over the body of the device, focusing on the bottom foot, and wipe it with a dry cloth after about 48 hours.
Almost all the exposed areas and openings are purple-brown to varying degrees.
If you feel that the color of the sole is too dark, you can scrub it with washing powder and polish it with fine sandpaper to make the sole appear slightly white, like a glutinous rice tire, which will give people a visual error.
Finally, the bottom is aged, that is, rusted.
Apply a small amount of 502 glue on the shrunken glaze, exposed tire areas and areas where you want to rust the surface, and pat on yellow mud. The yellow mud is preferably grave soil with a small amount of old lime in it.
You can also put a few iron nails on a certain part of the utensil and sprinkle some salt.
After a week, the rust on the porcelain surface cannot be scraped off with a knife, and it is difficult to remove it with hydrochloric acid.
The last step is to give it a bit of an old feel.
Throw some crumbs of sweets at the bottom of the utensil to attract insects, build spider webs, sprinkle cockroach droppings, and cover it with dust.
Chen Wenzhe has not used these old-fashioned methods for a long time.
This time he was reviewing old stories to learn new things, because he was really curious about Wu San and his friends' methods.
"It's just a small trick to make it look old, but it shouldn't go astray. Just try to imitate the craftsmanship!"
After studying porcelain making for such a long time, Chen Wenzhe already knew how to imitate Yuan blue and white.
The preliminary preparation is nothing more than using modern commercial circulation channels to obtain suitable or similar suma liqing materials.
Chen Wenzhe doesn't need to worry about this. In fact, in modern society, there are many more people who want to produce this kind of high-end cobalt material than he does. As long as he is willing to spend money, he can sell what he wants.
