Metal utensils are among the oldest in China, made from materials such as gold, silver, copper, iron, and tin. Before Qin Shi Huang unified China, bronze vessels were already widely used, both for alcohol and for holding tea or water. As tea became a beverage, tea ware gradually separated from other types of utensils. Around the Northern and Southern Dynasties, China saw the emergence of silver and gold tea ware. During the Sui and Tang dynasties, the production of silver and gold utensils reached its peak. From the Song Dynasty onwards, opinions on metal tea ware were mixed. After the Yuan Dynasty, especially starting from the Ming Dynasty, with innovations in tea varieties, changes in tea-drinking methods, and the rise of ceramic tea ware, metal tea ware, including those made of silver, gradually disappeared. Particularly, tea ware made of tin, iron, and lead was believed to alter the taste of tea, leading to their rare usage. Silver and gold tea ware can be classified by material: those made of silver are called silver tea ware, while those made of gold are called gold tea ware. Silverware decorated with gold foil or gilded is referred to as gilded tea ware. Due…

There are many "obviously fake" imitations and traps in the Purple Clay market. Many enthusiasts often ask us to authenticate various teapots. Here are a few types of teapots that you may have come across. Be very careful. Injection-molded teapots Pure Purple Clay cannot be used to make injection-molded teapots, so during the process of making these, a lot of glass water is added to the clay. The clay is placed in a ball mill for 48 hours, turning it into a very fine slurry. The slurry is then poured into molds, left for 1-2 minutes, taken out, dried, and processed into teapots. One person can produce 300-500 injection-molded teapots in a day. The glass water does not evaporate at high temperatures but seeps directly into the Purple Clay. Glass water contains water, alcohol, ethylene glycol, corrosion inhibitors, and sometimes methanol, formaldehyde, and glycol. Methanol is highly toxic to the human nervous and blood systems, causing toxic reactions when ingested, inhaled, or absorbed through the skin. Methanol vapor can damage the respiratory mucosa and vision. To deal with such fakes, first, do not be misled by low prices of a few dollars or tens of dollars, buying cheap teapots with…

What is 316 Stainless Steel? 316 stainless steel is an austenitic stainless steel containing molybdenum, which gives it superior corrosion resistance and high-temperature strength compared to other types of stainless steel. 316 stainless steel is commonly used in medical devices, food processing equipment, chemical containers, and other fields where material requirements are high. It contains 2-3% molybdenum, which enables it to maintain excellent corrosion resistance even at high temperatures. Advantages of 316 Stainless Steel Water Cups Water cups made from 316 stainless steel have many advantages that make them an ideal choice for brewing tea: (Image source: network, delete upon request) Strong Corrosion Resistance: The corrosion resistance of 316 stainless steel is very good, effectively preventing the corrosive effect of acidic substances in tea on the cup. Safe and Non-toxic: 316 stainless steel is harmless to the human body and does not release harmful substances, making it very suitable for brewing tea and storing drinking water. Easy to Clean: The smooth surface of 316 stainless steel makes it difficult for tea stains and bacteria to adhere, making cleaning very convenient.
