At the same time, the first health environmental protection purple sand product store listing ceremony was held by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China. The release of the "National Standard for Zisha Pottery" by the China National Standardization Administration will be implemented on June 1. The new standard specifies the technical requirements for the purple sander. Except for technical content requirements such as the water absorption rate, thermal stability, color of the finished product, etc. The strict limits are imposed on the allowable limits of the heavy metal lead and cadmium dissolution of harmful substances in the zisha pottery products.

The cadmium elution volume was increased from 0.3 mg/L to 0.50 in the original standard. Mg/L. China Indoor Environment Monitoring Committee issued a warning on health, safety and prevention of purple sand products.

Song Guangsheng, director of the China Indoor Environment Monitoring Working Committee, analyzed: The new standard has increased the control requirements for harmful substances of the purple sand pottery products, further defined the defining standards of the purple clay pottery raw materials, the technical standards for the production of purple sand pottery, and the technical requirements for the characteristics of the purple sand pottery products. The standards are more advanced, scientific, rational, and practical. After the implementation of the new standard, on the one hand, it will promote the technical progress and industrial development of China's Zisha pottery industry. On the other hand, it can provide a basis for consumers to choose safe and healthy basis for the use of zisha pottery products.

Zisha pottery is a classification of ceramics, a wide range of categories, but the highest reputation with the teapot, is a perfect combination of practicality and art, has always been loved by literati. Zisha pots are traditional Chinese crafts, and they are known as the “Literati Sanya” by ancients. In recent years, with the rapid development of the economy, the improvement of the quality of people's lives, and the rise of the collectors' fever, the only Chinese zisha that combines practicality, viewing, and collection has attracted more and more attention. The value of the purple sand pot is mainly reflected in the following three aspects:

First of all, China Zisha has a unique mud, the texture of the purple sand produced is delicate and tender, good permeability, and strong plasticity. Purple sand has good air permeability, but it does not leak water. Using a transparent, non-leaking pot of purple sand will have anti-corrosion effect, especially in the summer. It was found that using teapots in teapots, tea in winter is not cool, and teas in tea in summer are not. With its brown color, aroma, taste and taste.

Second, the teapot is a practical tea drinking appliance, and it is also a valuable artwork. Zisha tea sets are concise, generous, simple and elegant. With its use of tea, the longer the age of use, the more glorious the color of the body of the pot, the bubble tea will be even more mellow aromatic, even if the boiling water into the empty pot, there will be a light tea fragrance. However, the beauty of the teapot lies in its integration of arts such as modeling, painting, poetry, calligraphy, and seal carving with its unique clay materials and unique molding techniques.

Third, as a collection, Zisha Hu has a long history in China. The transaction price of high-end purple sand art is also constantly refreshing. On September 28, 2008, at the Zisha Minghu auction hosted by Shenyang Tea City, a “Yixing kiln, black lacquer, lacquer, lacquer, jar, jewellery and other pots” that was used by imperial courts during the Qianlong period was successfully auctioned at a price of 1.55 million yuan. At the auction held at the end of 2008, a teapot made by Gu Jingzhou, a famous contemporary teapot master, has already captured more than 3 million yuan.

Today, there are many counterfeit teapots on the market. The industry is called garbage pots. Due to the increasingly scarce shortage of raw materials for purple sand, some businesses will add chemicals to the purple clay to change the color, or use paint or even shoe polish. Brushing on the surface, on the one hand, drinking this potted tea with added chemical raw materials will harm the health of the body, and on the other hand, it will cause a crisis of confidence in the quality of the teapot.

China's Indoor Environment Monitoring Committee Song Guangsheng reminded consumers that because the purple sand pot and purple sand products are used by people for leisure and tea drinking, the dishes such as the purple clay stew pots and pans are closely related to people's dietary safety. The publication and implementation of the new national standard for Zisha pottery, especially the new standard, has improved the control of lead and cadmium in the harmful substances of the Zisha pottery, and provided consumers with health, safety, and environmental protection.

The damage to human health caused by counterfeit teapots and rubbish pots is mainly caused by the pollution of heavy metals such as lead and cadmium: the surface is brushed with chemical pollution.

When selecting the teapot, the first is to look at the color, not too bright, and the counterfeit and unconventional Zisha pot is thicker in color than the pot, especially bright. The second is to look at the water absorption of pots. Watering with boiling water and fast water absorption proves that the clay pot of the teapot is better because the most important feature of the purple clay mud is air permeability. The third is to see the price. Under normal circumstances, the price is 80 yuan. The following purple sand pot should pay attention to the quality. Consumers are advised to ask for inspection reports on harmful substances when purchasing zisha pottery and other products. Consumers should pay attention to harmful substances when buying and using zisha pottery and other food-type zisha pottery products. At the same time, they should choose to prevent rubbish pots and counterfeit products. And harm to human health caused by shoddy products.

The China Indoor Environment Monitoring Working Committee began the promotion and testing of the sanitary and environmental protection purple sand pottery products on June 1 and conducted free testing activities for harmful substances in the Zisha pots for 100 consumers in the Beijing area.

On May 30th, the China Indoor Environmental Monitoring Committee and the National Indoor Environmental Quality Inspection Center held a press conference and on-site inspection and consultation activities at the Yuquanying Flower Exhibition Hall in Beijing. At the same time, the first domestic health and environmental protection purple sand product, Laoyu Zisha Store was listed on the market. .
