繼曝出「美的紫砂煲造假」事件後，中央電視台《每周質量報告》再次將調查延伸至紫砂壺，發現市面上充斥著用化工原料調色的「化工壺」，還有人利用職稱弄虛作假，製作「代工壺」。當地一些經營「化工壺」的人都不用它喝茶，一名店主說，「化工壺」含有化工原料，有一定毒性。

中央電視台《每周質量報告》稱，因政府實施「禁礦令」，宜興原礦紫砂越來越少，於是一些煉泥廠開始摻雜使假，大量使用浙江、安徽等外地礦料或者普通陶土，通過添加化工原料或陶瓷色料進行調色，加工生產所謂的原礦紫砂泥。宜興一家紫砂壺加工點的老闆承認，黃龍山的礦早已封掉，他們用的泥巴有的來自浙江有的是來自安徽。

據專家介紹，原礦紫砂，就是採用形成於幾億年前的純天然紫砂礦料加工而成，不添加其他任何物質。但央視記者走訪被譽為「中國陶都」、紫砂陶器發源地的宜興市丁蜀鎮陶瓷城、雙橋村和尹家村等地見到，各種礦料在院子裏堆成一座座小山。其中一家練泥廠的生產車間，一名工人將一些紅色的粉末倒入水中攪拌、混合。據介紹，紅色粉末稱為「鐵紅」，全稱「氧化鐵紅」，又叫「鐵紅粉」，是一種工業原料，被廣泛用於塗料、橡膠、人造石等生產領域。

該工人承認，「鐵紅粉」一般用來加工「紅泥」，廠裏加工「紅泥」所用的原料較差，為模倣原礦紫砂，只好添加一些「鐵紅粉」增色。該練泥廠還添加「錳粉」、「(氧化)鉻綠」等化工原料來生產「紫泥」和「綠泥」。

一些廠甚至用更特殊的「黑色素」生產所謂的紫砂泥。「黑色素」即一種陶瓷色料，用其進行紫砂調色比一般化工原料好。主要成分包括鉻、鐵、鈷、錳、鎳等。

一名工廠負責人稱，市面上大部分「看上去很黑的紫砂壺」，都是用他生產的「紫砂泥」。

宜興的生產商和銷售商，都知道「紫砂調色」這一個公開的秘密。當地人均稱這種添加化工原料的紫砂壺為「化工壺」，經營此壺的人都不用它喝茶。一名店主說，「化工壺」含有化工原料，有一定毒性。

央視記者隨機購買15件紫砂壺和紫砂杯送到上海材料研究所檢測中心進行檢測。檢測項目主要針對記者調查時發現人為添加的鋇、錳、鈷、鉻等幾種重金屬元素。經過檢測，15件紫砂茶具，除兩件原礦紫砂茶具之外，其餘13件樣品重金屬溶出量都出現異常。專家指，長期攝入鋇、錳、鈷、鉻等金屬離子，就會危及人體健康。

《每周質量報告》還揭露，在紫砂壺銷售上，沒有職稱的人自封「助理工藝美術師」；有的人甚至刻多套印章，找人「代工」製作紫砂壺，然後刻上自己的印章賺取差價。

Detected harmful metals expert refers to long-term intake of health-threatening "stain" Yixing pernicious influence market 

Following the event of "America's purple pot fraud is exposed, the CCTV" Weekly Quality Report "again the investigation extended to the teapot, found that the market is full of color with chemical raw materials chemical pot, as well as the use of titles fraud, the production of foundry pot. Local management "chemical pot" people do not have to drink tea, one owner said, "Chemical maker contain chemical raw materials, have a certain toxicity. 
CCTV "Weekly Quality Report", due to the Government to implement the ban mine Order, Yixing Yixing ore less, so some mixing cement plants began to be adulterated, extensive use of Zhejiang, Anhui and other mineral aggregate in the field or common clay, by the addition of chemical raw materials or ceramic pigment color, processing and production of the so-called ore of purple clay. A Teapot in Yixing processing point boss admitted, Huanglong Mountain mine has long been sealing them with the mud and some from Zhejiang and some are from Anhui. 
According to experts, the ore Yixing, is to use the processing of pure natural purple clay mineral aggregate formed in the hundreds of millions of years ago made, do not add any other substances. CCTV reporter visited known as the "China Ceramic Capital", the birthplace of Yixing pottery the Yixing City dingshuzhen, Ceramic City, Shuangqiao Village and Yin Village and other places to see, a variety of mineral aggregate pile of a hill in the yard. Which a training workshop of the production of cement plants, a worker will be some red powder into the water, stirred, mixed. According to reports, the red powder called "Iron Red, full name of the red iron oxide, also known as" Iron Pink "is a kind of industrial raw materials are widely used in paints, rubber, artificial stone production areas. 
Recognition of the worker "Iron Pink" is generally used to process red mud, poor factory processing the raw material of "red mud", had to add some "Iron Pink" enriched imitate ore Yixing. The pug factory also added manganese (oxidation) and chrome green "and other chemical raw materials to produce the purple and green mud. 
Some plants even more special melanin production of the so-called purple clay."Melanin", a ceramic pigments, with its purple clay color than the average chemical raw materials. The main ingredients include chromium, iron, cobalt, manganese, and nickel. 
The factory of a responsible person, the market most of the "look black teapot, with his production of" purple clay ". 
The Yixing manufacturers and vendors, and all know the "purple color" This is an open secret. The local per capita of this teapot add a chemical raw material for chemical pot operating this pot of people do not have to drink tea. One owner said, "Chemical maker contain chemical raw materials, have a certain toxicity. 
CCTV reporter randomly buy 15 teapot and Yixing Cup to Shanghai Research Institute of Materials for testing. Test items for news investigation found that artificially added several heavy metal elements such as barium, manganese, cobalt, chromium. After testing, the 15 Yixing tea, in addition to the two ore Yixing tea, leaching of heavy metals in the remaining 13 samples are abnormal. The experts, the long-term intake of barium, manganese, cobalt, chromium and other metal ions, it will endanger human health. 
"Weekly Quality Report" also revealed that the teapot sales, titles self-appointed "assistant and crafts"; several sets of stamps, and some people even carved to look for "OEM" production Teapot, and then engraved own the seal make the difference.
