"Afterwards, Dayi discovered and scientifically cleaned up six kiln sites from the Han Dynasty. Not only were the working surfaces, kiln doors, fire chambers, kiln chambers, flues, and kiln covers well preserved, but they had also been scientifically cleaned and the data were complete."

"Therefore, whether judging from Du Fu's poetic description or the actual objects unearthed in Dayi, the Dayi kiln does not exist, and the white porcelain produced is very similar to the famous Xing kiln white porcelain in the Tang Dynasty."

"As early as the Tang Dynasty, the white porcelain utensils produced by Xing Kiln in Hebei Province were 'used by everyone in the world.' This shows that not only the utensils but also the craftsmanship should be popularized."

"And besides Du Fu, there are actually poets who also wrote poems praising the white porcelain tea bowls produced in Dayi, Sichuan."

"Oh? Really?" Mr. Zhang couldn't help asking: "Who?"

"Bai Juyi." Zhou Zhi said: "There is a poem by Bai Juyi in "Reminiscing about Yang Tongzhou over Tea After Sleeping": The white porcelain pot is very clean, the charcoal of the red stove is blazing. The fragrance of the dust under the foam, the flowers are floating on the fish's eyes."

"And there are two more sentences in the poem: There is a beautiful color when it is served, and the remaining fragrance is swallowed. If you don't see Yang Muchao, who would know this taste."

"The meaning of the poem's title is that Bai Juyi drank tea after waking up, recalling his good friend Yang Tongzhou and the scene of drinking tea with him back then."

"Yang Tongzhou in the title of the poem and Yang Muchao in the text are Yang Rushi, a Jinshi in Yuanhe. He served as Minister of the Ministry of Works, Governor of Tongzhou, Minister of the Ministry of War, etc., and was Minister of the Ministry of Civil Affairs at the time of his death."

"Bai Juyi was his sister-in-law, and there were many poems and poems sung between them. Yang Rushi once served as the governor of Dongchuan, so he learned the tea ceremony in the capital of Shu. In addition to this poem that mentions white porcelain bowls, Bai Juyi once

The lady wrote two poems to congratulate Yang Rushi and his wife. One of them also mentioned tea: the gold flower and silver bowls are reserved for the king, and the paintings and Luo clothes are all made by the sister-in-law. After finding Qian Lou as her sister-in-law, she may send tea from Shu.

"

"So it is conceivable that Yang Rushi at that time sent a lot of Shu tea to Bai Juyi, performed a tea ceremony with him using a white porcelain bowl, and tasted the fragrant tea of ​​Shu together, and Bai Juyi left a deep impression on him.

The porcelain bowl is most likely from central Sichuan."

So far, everything Zhou Zhi has said is a well-founded fact, and everyone has to nod.

Lao Chai said: "In fact, one of the most famous legends about porcelain in the Tang Dynasty is that of secret color porcelain."

"Yes." Lao Li said: "As for what color 'secret color' refers to, people used to have different opinions on this. Until April 1987, thirteen pieces of Yue kiln celadon were unearthed from the Tang Dynasty underground palace in Famen Temple, Fufeng County.

In the inventory that records the artifacts offered by the royal family at Famen Temple, this batch of porcelain is indeed recorded as 'Porcelain of a Secret Color'. Only then does everyone know what the secret color porcelain looks like, and it also proves that the legend is not a legend, but a reality."

"Actually, the secret color porcelain is the royal porcelain supplied to the Yue kiln, and the formula of the porcelain medicine is kept secret. Except for two pieces of the secret color porcelain in the underground palace of Famen Temple, which are green and yellow, the rest of the glaze is blue and green, crystal clear and moist, as clear and green as the surface of the lake."

Mr. Sun nodded: "This completely resolves the thousand-year-old controversy about whether secret color porcelain originated in the Tang Dynasty or the Five Dynasties."

"Also, the article 'No white porcelain in Dayi' was from the Peninsula Morning News. It is not an authoritative academic publication. It was also reported many years ago and has been overturned by later unearthed cultural relics and the latest research.

It can no longer be counted." Lao Wang said angrily: "The key is that this article comes from a publication in Liaodong. This clearly means that they want to say that their Liaobai porcelain is a category of porcelain that has historical data and physical evidence. Although the source

Xing Kiln is still worthy of pride."

"This is called stepping on us and standing out!"

"There is no need to incriminate this." Mr. Zhang waved his hand: "According to Zhuzi's statement, we can almost prove that there have been porcelain kilns for firing white porcelain in Dayi since the Tang Dynasty, right?"

Everyone nodded.

"However, the kiln entrance has not been confirmed so far." Zhou Zhi said: "But at least the porcelain is there. Even if the porcelain shards and porcelain unearthed before cannot be dated, this disk can actually prove its existence.

"

"You mean the words 'Tianbao Yongchang' here?"

"Yes, although there are countless supporting evidences, the four-character brown-green glaze inscription 'Tianbao Yongchang' on the inner edge of the circle at the bottom of the bowl is the most important proof."

"Tianbao is the reign name of Tianbao, Yongchang..." Mr. Zhang suddenly exclaimed: "In addition to being auspicious, Yongchang is also what Mo just mentioned. The kiln mouth with the white porcelain kiln king statue unearthed in Dongguanchang - Yongchang kiln!"

"Yes, experts believe that only the ceramic production in Sichuan and the Japanese archipelago shows the characteristics of a porcelain technology absorption area. Almost all porcelain production technologies and typical types of porcelain in various places can be referenced and inherited in the two places. Although Yongchang Kiln is a Song Dynasty kiln

site, but its inheritance is still the same, absorbing the characteristics of the northern and southern schools. The glaze color and embryo production method are more inherited from jdz, and the horseshoe-shaped kiln as well as the printing and carving styles are similar to the northern Ding kiln. "

"Chengdu Qingyang Palace Kiln, Liulichang Kiln, Qionglai Wayaoshan Kiln, Chongzhou Tianfu Kiln, etc. all produce white porcelain, and Pengzhou Cifeng Kiln mainly produces white porcelain, with a

Two layers of fine white layer are used as cosmetic clay to cover up the roughness of the original body and make the surface of the porcelain whiter and smoother."

"In addition to makeup clay, double colors, three colors, underglaze colors, etc. are all reflected in Sichuan porcelain, and the unique high-temperature underglaze composite colors and Qiong three colors of Qiong kiln are enough to leave a mark in the history of ancient Chinese ceramics.

It flourished in the Southern Dynasties and did not decline until the end of the Song Dynasty."

"As for the three-color and composite colors, there is no doubt that they are the three-color technology inherited from the Tang Dynasty. Therefore, the craftsmanship in Sichuan is similar to that in the Tang Dynasty and the Central Plains."

"Indeed." Mr. Sun nodded: "If you don't say this porcelain is from Dayi kiln, I will classify it as white porcelain from Xing kiln in the late Tang Dynasty."

"By the Tang Dynasty, the ceramic industry had made great progress, and many important technical achievements had been achieved. The output and quality of ceramics had been greatly improved."

"Due to the advancement and improvement of the entire porcelain industry, a large number of porcelain kilns appeared. In the end, the Yue kiln in the south for firing celadon and the Xing kiln in the north for white porcelain were the most highly regarded, forming the 'Southern Qing and North White'

This situation deeply affected the entire history of China's porcelain manufacturing."

"Lu Yu once made a very insightful evaluation in The Book of Tea: 'Xing porcelain is like silver, Yue porcelain is like jade; Xing porcelain is like snow, Yue porcelain is like ice'. Pi Rixiu wrote in "Tea Ou Poems":'

Both Xing kiln and Yue people can make porcelain. It is as round as the moon and light as the soul of the cloud.'"

Zhou Zhi added: "After the mid-Tang Dynasty, porcelain has been greatly popularized. Li Zhao said in "National History Supplement", 'Neiqiu white porcelain ou and Duanxi purple stone inkstone are used by everyone in the world.'"

"Later generations described the porcelain of Yue kiln and Xing kiln, and there are two witty sayings: 'ancient mirror is broken' and 'tender lotus contains dew'."

"'Ancient mirror's broken body' is easy to understand. It refers to the cyan color of bronze. After the broken body, the copper color inside is exposed, which is either purple or yellow. It describes the glaze color and body color of celadon in the Tang and Song Dynasties."

"The 'Nen Hehan Lu' is the glaze color and body color of Xing kiln white porcelain. Because the tire repair process is not pure enough, fine brush marks are left on the body, just like the veins on the lotus leaf petals; and
