Purple sand mines are increasingly scarce, so many manufacturers will use purple sand substitutes when making purple sand liners, mainly including:
1, mud and chemical raw materials.
2, ordinary stone powder plus additives.
3. Color matching production of purple sand secondary ore.
The above-mentioned situation that the self-explosion purple sand liner of an electrical appliance manufacturer in Guangdong was replaced by purple sand can be explained as follows: in the related terms of "purple sand", "purple sand pot" and "purple casserole", some people declared that "I think according to the national standards, the purple sand products on the market now belong to a large family of purple sand pottery, and the quality can only be said to be uneven. Many purple sand tea sets in Yixing are excellent purple sand products, such as "Beauty" and "Jiuyang" in the market. However, some products have rough technology, high water absorption and poor quality. " It is the black hand of "Beauty Theory", "Jiuyang" and "Yili", trying to block the long mouth on the Internet, not only not wanting to bear the fault responsibility, but also wanting shattered glass to deceive unsuspecting consumers and readers. Five-color stone ointment: paste-like things are called ointment when they are condensed together. It is very sticky in nature, and it is good for fixing the stove and the lid is also dual-purpose. The annotation proves that purple sand comes from five-color stone grease. Shi Ming's essence is like stone and sticky, hence the name five fingers. There are different types of bluestone grease, yellow stone grease, black stone grease, white stone grease and red stone grease, which are collectively called "five colors and five fats". Halloysitum rubrum is the most commonly used medicine, white stone is rarely used, and bluestone, Huangshi and Blackstone are not used as medicine. Beware of the so-called market bluestone oil, also known as "green mud", which requires the state to formulate monitoring content and quality standards.
If you make red grease, grind it into powder, fly it with fresh water for more than three degrees, and dry it. Even the original high-quality red fat (purple sand) should be "pumped (not) three times and dried", which is enough to prove that a manufacturer has a well-founded foundation for soaking purple sand in vinegar to detoxify. How can fake natural purple sand such as Midea, Jiuyang and Yili be put off?
Smell: All five oils are sweet, flat and nontoxic.
Don't record that five-color stone resin was born in Sunshine Valley of Nanshan. He also said: there is stone grease, living in mountains and seas (now called green mud) Yellowstone National Park's fat Kobresia Mountains are as colored as little warblers. Blackstone gives birth to Yingchuan Yangcheng. White stone fat gives birth to the yin of Mount Tai. Halloysitum rubrum is produced in the shade of Jinan, Sheyang and Taishan. Spend all your time.
Hongjing said that today's customs only use red stones and white stones. Good quality comes from Wu Jun (now Jiangsu). There are also people from Wuling, Jianping and Yiyang. I don't know which county Yiyang is from. It looks like a lonely brain, red and lovely. Resurrection by mining. The remaining tricolor stone grease has no proper function. But Blackstone grease can be used for painting.
It is said that Yiyang is China and produces peach stones, not stone fat. The white stone comes out of Ciyang Mountain today, which is better than the rest. Halloysitum rubrum is produced in Lushi County, Zezhou lingchuan county, Luxiang County, Cizhou County and Yizhou Mountain Area, and it is better to be fresh and greasy. I haven't heard of Erzhi Taishan. It used to belong to Suzhou and Yuhang Mountain, but it's not accepted today. (The reason why Fan Li went boating in Legend Lake with the stone in the teapot shows that there are not many purple sand resources in Jiangsu at this time, and mining is no longer allowed. )
It is said that both Baishizhi and Hongshizhi are from Luzhou, not far from Cizhou.
According to Compendium of Materia Medica, purple sand mines are distributed not only in Yixing, but also in Luzhou, Yishan and Yiyang. Due to the differences in understanding between ancient and modern characters, many modern people don't know the relationship between five-color stone grease and purple sand, which gives many unscrupulous manufacturers room for deliberate speculation. As for the medicinal efficacy of five-color stone oil, dialectically speaking, individual differences vary from person to person, so we should follow the doctor's advice and don't blindly follow the trend to cause overheating, so that illegal manufacturers can take advantage of it.
The so-called exchange of resources for dollars is even more ridiculous. "Why don't we leave the best products to our own people?" It is really heartbreaking that some unscrupulous traders trick consumers into buying inferior so-called teapots. The kind of "suggestions and appeals" that evade responsibility: CCTV reporters, as non-professionals, jump to conclusions without consulting industry experts and the national quality inspection department, which will cause people to panic! China is a big producer and exporter of ceramics, and the ceramic industry is also a traditional labor-intensive industry in China. The "Zisha Gate" incident happened twice in less than 20 days, which was a fatal blow to the industry. "Cry more pale and rash. Some people in China should not enjoy their own high-quality products. China people don't have this spending power?
Toyota, Honda, Hewlett-Packard, etc. I am stingy with foreigners (they have never recalled the quality products of China consumers), but I have never been stingy with my own people and kept the best things for myself. If there is a problem, recall it. This "Zisha Gate" incident has harmed our own people. It is not as good as a Taiwan-funded enterprise "Foxconn" to explain to consumers. Following HP's "Sudan Red", "Melamine" and "Flash Screen Door", another "Zisha Door" incident with heavy hidden rules and collective fraud broke out in the purple sand industry.
China's feed and aquaculture industry also has deep "hidden rules". For example, after the "Sudan Red" incident, Japan, the United States, Europe and other developed countries have taken natural astaxanthin as a natural health additive or natural astaxanthin as a natural food colorant. Because natural astaxanthin is the strongest antioxidant in nature, it is widely used in food, health care products and cosmetics. However, natural astaxanthin is rarely used in feed and aquaculture in China, and most of them do not use natural astaxanthin at all or are replaced by cheap spirulina. According to insiders, spirulina is used to replace astaxanthin in order to reduce the cost to the maximum extent, and chlorophyll and β -carotene in spirulina are used to achieve the coloring effect. What's more, it deceives consumers with synthetic astaxanthin. Among them, the industry standard of "feed and aquaculture" is even more confusing, and the "synthesis gate" of this industry is provided by seven natural astaxanthin companies in the world and Jingzhou Natural Astaxanthin Co., Ltd., the first in China.
It is reported that the "National Standard for Zisha Pottery" jointly issued by AQSIQ and China National Standardization Administration Committee does not specify the composition of Zisha Pottery, but only explains the technical requirements of Zisha Pottery. Bao Zhiqiang, a master of arts and crafts in China who participated in the formulation of the national standard of purple sand pottery, confirmed that the national standard of purple sand pottery stipulated the water absorption rate, thermal stability, allowable limit of lead and cadmium dissolution and the error value of caliber height. This standard is applicable to purple clay with fine texture, high iron content, rich trace elements necessary for human body and improved water quality. Hard and breathable unglazed purple sand pottery inlaid by hand knocking actually does not include grouting, mechanical molding and water quality.
It remains to be seen whether there are more "hidden rules" in the industry that we need to explore and discover the truth.

On June 17 and June 18, China Household Electrical Appliances Association and China Ceramic Association held seminars on the production and application of household electrical appliances ceramics. On June 2 1, official website, the above-mentioned association, announced the results of enterprise sampling inspection and expert appraisal, and the two associations issued a joint statement: experts attending the meeting agreed that purple sand belongs to pottery, purple sand is a "safer inorganic material", and purple sand mineral materials in other regions can also produce purple sand products, but the cultural connotation of Yixing purple sand is the most prominent.
From the weekly quality report of CCTV on May 23rd, nearly a month after the "Zisha Gate" incident that caused an uproar in the society, this authoritative department finally came to a conclusion.
Expert five points: purple sand is safe and nontoxic.
At the seminar on the production and application of ceramics for household appliances, the opinions of experts were unified as follows: 1. Ceramics are the treasures of traditional culture in China. Specifically divided into pottery and porcelain, purple sand is a kind of pottery, purple sand is a safer and more hygienic inorganic material; Second, iron oxide, manganese oxide, zinc oxide and other materials can be added to the purple mud liner after molding, because crystals will be formed after being fired at a high temperature of 1 100 degrees, and this crystal has good chemical stability. It is insoluble in water or weak acids. Non-toxic, harmless, safe and hygienic; Third, according to the national standard of fine ceramic cookers, the purple clay pot products produced by Midea, Jiuyang, Supor and Yili are safe and non-toxic; Fourth, the 2008 edition of the national standard Zisha Pottery (GB/T 108 16—2008) has an authoritative definition of what Zisha Pottery is: "It is made of special clay with fine texture and high iron content, with reddish brown color, hard texture and good air permeability". Zisha Mine is not unique to Yixing, Jiangsu Province, and has relatively rich reserves in China. Purple sand mineral materials in other areas can also produce purple sand products that meet the standards, but the cultural heritage of Yixing purple sand is irreplaceable; 5. Pottery is a kind of ceramic surface decorated with cosmetic soil, which is a common process method in ceramics and can produce products with excellent performance. If the carcass of the product is not reddish brown, it is not appropriate to call it "purple sand" only with cosmetic soil as decoration.
In addition, the experts at the meeting put forward three suggestions: first, they called on enterprises to operate in good faith and conduct lead and cadmium dissolution tests in strict accordance with the requirements of national standards when producing such products; Second, enterprises should strengthen the popularization of purple sand culture; Three, the news media can consult experts in advance when reporting.
The "Zisha Gate" was revealed to the world.
Since "Zisha Gate" is a false alarm, whether it is "Zisha Fake" or "Zisha Poison", the truth of the "Zisha Gate" incident is a simple question: the direction of public opinion seems to be biased: in fact, according to Article 5 of the joint statement and appraisal result of China Ceramic Association and China Household Electrical Appliances Association, if the product matrix is not reddish brown, it is called "if it is only decorative cosmetic soil". This is also the first time that the authoritative department responded positively to CCTV's Weekly Quality Report, exposing the problem that the color of purple clay pots produced by Midea Electric was "inconsistent" after the purple clay pots produced by Huaihua, Hunan Province were exposed. However, due to the panic of consumers and the extension of individual media, all enterprises in the whole industry have been affected, including products produced by Jiuyang, Yili, Supor and Sanyuan. All of them were passively removed from the counter, and the enterprises producing teapot and teapot stopped working, and a large number of workers faced layoffs. Just as some "hardcore" old experts engaged in purple sand research pointed out bitterly: "Because of a company's dishonest behavior, a stick killed the whole industry, which is almost a disaster that China purple sand culture has developed for thousands of years!" .
Perhaps because of a series of food problems such as melamine, people have become particularly sensitive to food safety. They confuse the safety of "food" with the safety of "food containers". Some people even say that the "Zisha Gate" incident is "melamine" in the home appliance industry, which is a bit alarmist. In fact, some experts have long questioned whether the "Zishamen" incident will become a major injustice in the history of quality inspection.
In fact, a simple truth is that since the country has a set of industry standards and quality inspection standards, if it is toxic and harmful, the quality inspection department and the industrial and commercial department have already made a punishment judgment. In fact, so far, according to media reports, the AQSIQ or SAIC, which is really qualified to speak, has not determined which enterprise is fraudulent or has quality problems.
Previously, because this incident has been inconclusive, consumers are worried about large-scale "poisoning" and have flocked to shopping malls to return goods, claim compensation and complain. The authoritative interpretation of this incident by China Ceramics Association and China Household Electrical Appliances Association, the most authoritative institutions in China to identify purple sand pottery, finally made the "Zisha Gate" incident that lasted for nearly a month come to the bottom.
According to an insider, the so-called "teapot" of Midea, Jiuyang and Yili mentioned above was not refunded, returned or paid according to the contract, but was all returned to the manufacturer by the dealer and put on the market for "red teapot".
Although the "Zisha Gate" incident only won the sympathy of the society under the indignant complaints of the media and consumers, it did not get the full support of the relevant government. With the passage of time and the "cyber killer" covering up the truth everywhere, the "river crab" of the media has gradually been forgotten. There is no doubt about the nature of fake natural purple sand in red mud mines such as Midea, Jiuyang and Yili. However, there is still a long way to safeguard consumers' right to know about the "Zishamen" incident without the relevant state management authorities to standardize and implement industry standards.
