The difference between Jun kiln and Ru kiln porcelain is obvious in many aspects.
For example, the firing temperature of Ru porcelain is 1200°C.
Furthermore, the water absorption rate of Ru porcelain carcass is relatively low, which is completely different from Jun porcelain.
From this point, it can be seen that the difference in firing temperature is huge, as can be imagined.
Also, when the temperature of Jun porcelain reaches 1200 degrees, the temperature will rise more slowly.
Fourth, the firing process is different.
Due to the high firing temperature of Jun porcelain, special attention must be paid to its firing and prevention of deformation.
The bottom part is often treated with a thin glaze of sesame paste with a lower concentration.
Since the body of Ru porcelain has low water absorption and is not easy to deform, craftsmen often apply glaze to the body, and then use pins to burn it.
This item is also a fundamental difference.
Fifth, the glaze bubbles in the glaze layer of Ru porcelain and Jun porcelain are different.
I hope my friends can use a magnifying glass (preferably 80x) to observe carefully and understand this.
The glaze bubbles in Jun porcelain glaze are densely packed, scattered and have some rhymes;
The glaze bubbles in the glaze of your porcelain are sparse and have a vague feeling.
The saying "Jun and Ru are indistinguishable" is not difficult for real insiders to distinguish.
Although the raw materials used at the kiln entrance are basically the same, the processes are roughly similar.
Even craftsmen from the two places learn from each other.
What's more, some kilns fired both Jun porcelain and Ru porcelain, showing a unique phenomenon of me in you and you in me.
During the excavation and investigation of ancient kiln sites at that time, it was found that a large number of fragments of azure, sky blue and red-spotted glaze handed down from ancient times were found in the kiln sites in Yu County and Linru.
This is the origin of the saying "Jun and Ru are inseparable" that is widely circulated in the collecting community.
In fact, Jun porcelain and Ru porcelain, as two famous porcelain types in Henan, have many differences in terms of glaze composition and firing process:
What I just mentioned is that the chemical elements of the glaze are different. In fact, the thickness of the glaze is also different.
Jun porcelain generally has a thicker glaze, while Ru porcelain has a thinner glaze.
The firing process is also different.
Jun porcelain is generally covered with glaze on the inside and outside of the base, while the exposed feet are sesame color (brown-yellow).
The base of Ru porcelain such as plates, bowls, tripods and other utensils is covered with glaze, which is like wrapping the base with glaze and burning the inner base with pins.
When firing, apart from the temperature difference, the biggest difference is in the quality of the embryo.
Different fetuses have different densities.
Jun porcelain's bubbles are dense, while Ru porcelain's bubbles are sparse.
Therefore, the so-called "Jun and Ru are indistinguishable" generally refers to ancient porcelain.
Because at that time, there was not much difference in the colors of the fired products.
Today's Jun porcelain and Ru porcelain can be identified based on the richness and changes in glaze color.
As for glaze colors such as azure, sky blue, and moon white, if you are a little more careful, you will also find obvious differences.
After careful study, there are many differences between Jun kiln and Ru kiln.
There were five famous kilns in the Song Dynasty, including Ru Guan Ge Jun Ding, but among them, Guan Kiln and Ge Kiln in the Northern Song Dynasty, no clear kiln sites have been found so far.
Even experts who specialize in this area of knowledge still cannot give you an accurate answer.
And the legendary firewood kiln is extremely rare and has not been passed down - so before talking about Jun kiln and Ru kiln, we have to mention the firewood kiln.
Firewood kiln does not refer to a kiln made of firewood, but because the second emperor of the Later Zhou Dynasty was named Chai Rong.
One day, the heavy rain stopped, and the sky was as clear as a green. Zhou Shizong saw the color as very good.
So he told the kiln official: "I like the color of the sky after the rain very much. Go and make one for me quickly. If you can't make it, it will click for you!"
After the rain, the sky is clear and the clouds are discolored. This color represents the future.
Later it was speculated that it was fired. Ouyang Xiu once described Chai kiln like this: Chai's kiln has a color like the sky and a sound like a chime. It is rare in the world. Those who get fragments use gold ornaments as utensils.
The closest thing to the azure color of the wood kiln is the Ru kiln. In order to achieve the height of the firing process recorded in the records, the Ruzhou kiln was established in the Northern Song Dynasty.
Cao Zhao of the Ming Dynasty described it this way in "Ge Gu Yao Lun": "Ru kiln wares came out of the north and were fired in the Song Dynasty. They are light blue in color and have crab claw patterns. Those without patterns are especially good. The earthy veins are charming and thin.
It’s even rarer.”
The rest is easy to understand, but what does "Tu Mei Zi Mei" mean?
This means that the surface of the porcelain has a very high gloss and smoothness, and is as moist as a layer of oil brushed on it.
The characteristic of Jun kiln is its gorgeous and eye-catching colors.
"Earthworm mud patterns" are common on the bowl body, and some of them are red in color, which is unique in the world.
In the Song Dynasty, which was dominated by elegant aesthetics, it can be said to be unique.
In order to produce different glaze colors during firing, Jun kiln will put copper, iron and other metals into the porcelain to produce a chemical flame color reaction.
When strange colors appear, ancient people were superstitious and believed that they must be caused by monsters. They usually smashed them to drive away the monsters, so the ones handed down are very precious.
Although porcelain is very beautiful, don’t imagine that you can pick up any leak at the entrance of the five major kilns.
Don't do stupid things like take out all your belongings and buy a bottle.
There are many cases where experts make mistakes, let alone a layman trying his luck.
Don't think about the dream of picking up leaks. People who really like porcelain can choose to buy handicrafts imitated by you.
There are quite a few well-known ones online. When choosing, be sure to choose beautiful and cheap works.
Chen Wenzhe seems to have followed this trend and developed his Yi Niantang.
On this day, Chen Wenzhe, based on market guidance, while making Junci, conveniently made an internet celebrity product - the Ruci Xueyin Cup!
"Poems are like natural flowers, spring orchids and autumn chrysanthemums, each has its own beauty."
In fact, small teacups are like this, with different shapes, and designers will adopt various methods when interpreting beauty.
Chen Wenzhe was very moved by the design of the Xueyin Cup. It has tall legs, freedom and lightness, and eliminates the dull feeling that is common with thick tires. It is compact and stable, but also smart and elegant.
The broad shape strives to embrace every inch of sunshine.
When the agate is put into the glaze, it will naturally change in the kiln.
Under the sun, there are endless changes.
It's like blue and green, it's wonderful.
In particular, the design of the rim is unique and smart, and the curved lines of the cup body are soft and cute, making it full and full to hold, making it particularly elegant when drinking tea.
The snow disappears, the snow disappears, and everything revives. This is the time of spring.
This cup combines the spirit of spring and the perseverance of winter, using the shape of a thick tire to create the spirit of a thin tire.
Meng Chun drinks tea in a cup hidden in the snow, to socialize in spring and winter, when the snow disappears and the grass grows, looking forward to the coming of spring and the rising sun.
Xueyin Cup is a cup type that has been created for the longest time by a master of modern craftsmanship.
It inherits the beauty of the bamboo hat and uses minimalist lines to express poetry and the charm of natural frost and snow.
Taking into account the artistic conception and practicality of the vessel is a test of craftsmanship.
If the body of the vessel is thicker, it will look dull, and if it is thinner, it will look a bit dull. The charm of both thickness and thickness is suitable for it, so that the charm of the vessel can be expressed.
