These celadon pottery tea mugs exhibit the traditional inlaid cloud and crane design with the attractive jade blue glaze that bestowed Goryeo (918-1392) celadon with a worldwide reputation. Each of these fine celadon mugs with accompanying lids contains a ceramic tea strainer to help users enjoy tea brewed directly from tea leafs. The floating cloud and freely flying crane designs representing eternity, combined with the color of autumn sky, gives the viewer the sensation of looking at a piece of heaven.
