Reduction fired zhuni appears black, even darker than wuhui zini. The clay has the same properties as zhuni fired in oxidation firing, but appears black instead of red\/orange.\u003c\/p\u003e\n\u003cp\u003eFiring a teapot in a low-oxygen environment is called “wuhui” 焐灰 which can be loosely translated as “smother with ash to fire.” The teapot is stuffed with dry rice straw, placed in a clay box and surrounded with more rice straw before being covered. When it is fired in this way, the straw uses the oxygen when it burns to ash, reducing the oxygen in the clay box while the teapot is being fired. This creates the reduced oxygen environment that gives the clay its black appearance.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.mudandleaves.com\/teatime-blog\/what-is-heini-wuhui-and-black-yixing-teapots\" target=\"_blank\"\u003eYou can read our blog entry here to learn more about the reaction that occurs in a reduction environment to give the clay this appearance in our blog post here.\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eZhuni Dahongpao is a special grade of zhuni named for its deep red-orange hue. The small amount of zhuni dahongpao ore (unprocessed clay) was handpicked by Lin Hanpeng from zhuni mined from Xiaomeiyao in Yixing. \u003c\/p\u003e\n\u003cp\u003eThis is an yixing teapot made from a rare type of zhuni clay known as Zhuni Dahongpao. The ratio of dahongpao ore to regular zhuni ore is said to be 1:100, or 1kg of zhuni dahongpao ore for every 100kg of zhuni ore. Dahongpao zhuni has a greater amount of Fe2O3 iron oxide than regular zhuni giving it a deeper red-orange hue. It also contains a lower percentage of Al2O3 aluminum oxide than regular zhuni, making it more difficult to fire without breaking. The range of temperature for firing dahongpao zhuni successfully is very narrow. It also has a higher shrink rate than regular zhuni, sometimes shrinking as much as 40%.\u003cbr\u003eYou can read more \u003ca href=\"https:\/\/www.mudandleaves.com\/teatime-blog\/the-3-kinds-of-dahongpao-clay\"\u003eabout Zhuni Dahongpao here\u003c\/a\u003e, and more \u003ca href=\"https:\/\/www.mudandleaves.com\/teatime-blog\/yixing-zhuni-part-1\"\u003eabout zhuni clay here.\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eThis pot is known as \"half-handmade\" as the sculptor uses a molding tool to shape the body, and uses his hands for the handle, spout, holes, and smoothing out the body. In fact, no machine was used in it's shaping as the use of the tool is entirely manual.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePreparation Before Use\u003c\/strong\u003e\u003cbr\u003eYixing Teapots should be prepared before using the first time. This is called \"opening the pot\". It removes the dust from firing the teapot.\u003cbr\u003eWe recommend rinsing the teapot under warm water two or three times, then filling the teapot with boiling water and emptying it out two to three times. After this the teapot is ready for use.\u003c\/p\u003e","brand":"MudandLeaves","offers":[{"title":"Default Title","offer_id":49048533500123,"sku":null,"price":229.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0539\/0768\/5574\/files\/DSC09866.jpg?v=1785437946","url":"https:\/\/mudandleaves.com\/products\/heini-wuhui-zhuni-dahongpao-limao-yixing-teapot-%e7%84%90%e7%81%b0%e6%9c%b1%e6%b3%a5%e5%a4%a7%e7%ba%a2%e8%a2%8d%e7%ac%a0%e5%b8%bd-115ml","provider":"MudandLeaves","version":"1.0","type":"link"}
