钧窑天蓝釉三足炉，北宋—金，高3.75英寸，口径2.75英寸。炉圆口，折沿，直颈，鼓腹，底下承以三足，整器线条简洁有力，规整庄重。施天蓝色釉，外壁满釉，渗出铜红色窑变。口部边缘釉薄处黄棕色胎质清晰可见，底部露足，可见釉层肥厚莹润。钧窑烧造做工考究的陈设用瓷，如花盆、花盆托、鼓钉洗、出戟尊等。这类陈设用瓷在清宫中多有收藏，被称为传世钧瓷。除此之外，钧窑也生产碗、盘、瓶、炉等日用品，产品多施天蓝色釉。 This Jun ware censer is well azure glazed with rose-bengal plaque. Bubbles can be seen from internal surface of the bottom, and the glaze barely covers three feet that hold the censer. The external glaze shows crazed sign. The most striking and distinctive Jun wares use blue to purple glaze colours, sometimes suffused with white, made with straw ash in the glaze. They often show "splashes" of purple on blue, sometimes appearing as though random, though they are usually planned. A different group are "streaked" purple on blue, the Chinese describing the streaks as "worm-tracks". This is a high-prestige stoneware which was greatly admired and often imitated in later periods. But colours range from a light greenish-brown through green to blue and purple. The shapes are mostly simple, except for the official wares, and other decoration is normally limited to the glaze effects. Most often, the "unofficial" wares are wheel-thrown, but the official ones moulded. Demensions are: 3 3/4 inches tall X 2 3/4 inches wide.
