Is there a market for high-end teapot shops in Zhengzhou now? Where should I choose? Please give me a suggestion!

Recently, the report on the problem of purple sand products has aroused strong concern from all walks of life, and the hot discussion on the quality of purple sand products can be seen in all streets and alleys. For a time, the word "purple sand" became a key word that swept the country. Just when people were ignorant, curious and suspicious about the quality of purple sand, a dialogue between purple sand masters and enthusiasts was held in Beijing Xinbaoli Building on June 1 day to answer questions and solve many misunderstandings caused by unprofessional narration.

At the same time, through interviews, people from all walks of life have said that at present, we must first solve the problem of popularization of purple sand knowledge, and secondly, we must see the mainstream development of the entire purple sand industry, and we cannot generalize because of some individual phenomena. People from all walks of life agree that the overall development momentum of purple sand industry will continue to rise, and in the upcoming new round of spring auction, purple sand art will achieve new success in the market.

"It is alarmist to say that the chemical kettle"

At present, the so-called Yixing teapot is a "chemical teapot", and consumers are worried that some teapots with chemical raw materials will cause harm to human body. Shi, president of Yixing Ceramic Industry Association, stressed that purple sand itself contains many chemical elements, and there is no such thing as a "chemical teapot". "If someone says this, it is alarmist."

Shi pointed out that the value of Yixing purple sand products and works lies not only in the raw materials, but also in the style and concept of the producers. For those masterpieces with strong artistic expression, the high grade and purity of the materials of their works can be completely guaranteed. At present, people who love Yixing purple sand are very extensive. In order to meet the needs of customers at different levels and make purple sand products and works, such as purple sand pots, bright in color, it is necessary to add an appropriate amount of oxides. Personally, he thinks it is ok, but it cannot exceed the standard and is harmless to human body. However, in order to attract consumers, it is absolutely wrong and not allowed for some merchants to make old teapots with shoe polish. This is a shameful act of deceiving consumers and damaging the purple sand market to some extent.

Shi said that in order to ensure the source of Yixing purple sand market, Yixing Municipal Party Committee and Municipal Government has taken measures to supervise the processing of purple sand raw materials, trace the source of market end products, investigate and deal with dishonest business practices, and resolutely safeguard consumers' rights and interests. At the same time, actively cultivate large credit markets and credit merchants to win the trust of consumers. As industry associations, they will also guide practitioners to enhance self-discipline through a series of activities and further polish Yixing Zisha business cards.

"Zisha raw materials can't distinguish authenticity"

Du Jianghua explained the misleading problems in some reports at present:

■ The minerals contained in purple sand cannot be preserved.

Du Jianghua pointed out that the pot seller was quoted in the relevant report: "Raw purple clay contains many minerals, so making tea with purple clay pot can keep you healthy." This is obviously misleading and exaggerates the efficacy of purple sand-the teapot is just an instrument or container for making tea, and the minerals it contains can't be eaten. The characteristic of purple sand is that "the original sand can be used to make the color and fragrance of real tea". Good tea and water can keep you healthy. In other words, a good pot can be enjoyable, pleasant and beneficial to the body and mind, thus nourishing the heart and body.

■ Metal elements with high melting point in the pot are insoluble in tea.

Du Jianghua pointed out that it is a bit rash to describe a pot containing cobalt and other metal oxides in mud as a toxic teapot in relevant reports. He said that these metal elements have high melting points, so that they can withstand the firing temperature of purple sand 1200 degrees. After high temperature firing, they have become a part of the matrix. How can we dissolve them into tea that Baidu can't? If these "metal elements" can't be dissolved in tea, how can they enter the human body? How can it be toxic and harmful to people if it does not enter the human body? In fact, cobalt oxide is used in the production of blue and white porcelain. Transparent glaze has nickel and white glaze has lead. If these metals can enter the body, then all these glazed ceramic products are not toxic.

■ The color matching between purple clay and metal oxides has existed in the Ming Dynasty.

Du Jianghua said that the earliest records of "matching soil" in the history of purple sand were Chen Zhongmei and Shen Junyong during the Wanli period of the Ming Dynasty. They are from Wuyuan, Jiangxi Province, and were originally engaged in the porcelain industry in Jingdezhen. Porcelain production in the Tang Dynasty used cobalt imported from Persia, and Jingdezhen had the best blue and white porcelain in the Yuan Dynasty. Chen Zhongmei and Shen Junyong have mastered the application of "pigment" in the production of porcelain industry, and then applied it to the production of Yixing purple sand, which has made more color changes in Yixing purple sand production, which should be said to enrich and improve the creation of purple sand. As early as 15 BC to 14 BC, there were utensils made of "green Jin Lan cobalt material" in Egypt and West Asia. China also imported cobalt from Persia in the Tang Dynasty, and later used its own cobalt materials, which are still used in porcelain production.

■ There are quality differences in raw materials of purple sand, which cannot be distinguished by "authenticity".

In view of the so-called "the most authentic raw material mine of purple sand has long been closed, and there are many low-grade purple sand mud extracted from" fake purple sand "similar to purple sand mud", Du Jianghua pointed out that it is generally believed that the purple sand mud hidden in Huanglong Mountain in Dingshu Town is the best and most authentic, which is not wrong. And the surrounding geography and landform are very close to the mountain structure, and the relevant mine sources cannot be ruled out, so why can't it be used for the production of daily tea sets? This may be different from the origin of Huanglong Mountain in quality, but this is only a quality difference and cannot be distinguished by "true and false purple sand".

■ The production of ceramic raw materials factory is inseparable from "chemical raw materials"

According to Du Jianghua, a ceramic raw material factory of iron oxide, manganese oxide and other metal oxides that appeared in relevant reports in Yixing has been closed down for rectification. But we have to clarify right and wrong first, and others will explain more if they don't say it. In fact, all ceramic raw materials and glazes are inseparable from these metal oxides. If ceramic products are really harmful to people, compared with glazed products, the influence of purple sand is the smallest.

"Some unprofessional people said unprofessional things."

On the morning of June 2nd, Gu Shaopei, a master of arts and crafts in China, who just finished his lecture on Zisha in Beijing, immediately returned to Yixing for a meeting to promote the popularization of Zisha culture. Under the current situation that people "talk about the color change of purple sand", he said that "some unprofessional people said unprofessional things", which caused people's misunderstanding. It is imperative to popularize basic knowledge and formulate product quality standards.

In an interview with reporters, Gu Shaopei pointed out that he didn't agree with the current theories of "chemical products" and "chemical raw materials" of purple sand products, because the raw materials of purple sand itself contain a variety of metal elements, which is also the reason why purple sand is colored, but we still call it "purple sand mud" instead of "chemical mud".

Gu Shaopei said that some people are unprofessional, especially those who do business. For example, in TV reports, some merchants said that the teapot mixed with cobalt oxide was poisonous, and they didn't even need to drink tea. Gu Shaopei stressed that these pot sellers didn't understand, let alone make it clear to others. As a result, the influence was very bad. At the same time, some products in the shops involved in CCTV's report on purple sand products, in the eyes of professionals, are the wrong temperature or some decorative coating materials have problems.

Gu Shaopei said that in purple sand mud, some things can be added, some things can't be added, and some things can be added, but there is no reasonable formula or regulation for adding more and less. Therefore, in this regard, I very much hope that the relevant departments can establish a system that can be monitored. For example, in his purple sand factory, in terms of raw materials, there is a special person to manage the formula and a special person to manage the chemical raw materials, all of which are produced under monitoring. At the same time, ordinary purple sand products and purple sand works of art have different grades in raw materials, each with its own standards, and cannot be generalized. So now we need to formulate standards, quality standards.

At the same time, regarding the so-called "purple sand is extremely scarce" in the current market hype, Gu Shaopei said that from the Ming Dynasty to the present, the clay we used only accounted for a fraction of the reserves, and the resources were no problem. The key problem is that it is non-renewable. The purpose of mine closure is for more reasonable development and utilization.

Gu Shaopei emphasized earnestly that purple sand is a long-term topic, and we should not simply expose some negative situations, but do more professional knowledge reports. There should be positive publicity and increase publicity. It is hoped that the media will focus on the big interests and play a positive role in promoting the development of the purple sand industry.

"You can't cover the whole industry with individual junk products."

Xu Yanchun pointed out that exposure is a warning to the current situation and reminds practitioners to strengthen self-discipline. But we can't catch garbage all day to cover the whole purple sand industry and cover up the mainstream. She said that the publicity of the content and celebrity representative works that represent the mainstream of our purple sand culture is still insufficient. She very much agrees with Gu Shaopei's point of view: At present, the mainstream of purple sand industry is that craftsmen want to do their own things well and use the best raw materials in their works to achieve more perfect results.

Xu Yanchun said that we should face up to the difference between ordinary products and artworks. Artists will take every material they use very seriously. From ancient times to the present, purple sand craftsmen will use their works first and then let them enter the market. As an industrial production, it is mercenary. So if there are any problems with industrial products, the regulatory authorities should establish a mechanism to regulate management. Yuan Linzhang Yao Qianghou Xiao Wei
