宋代怀仁窑油滴盏:拍品尺寸:高度:6cm, 口径:10.8cm。此盏敞口,深腹,腹壁圆弧,折腰。下承小圈足,足墙较宽、旋削规整,造型沉稳大气。胎壁厚实,胎土呈紫红色。外罩黑釉,内壁满釉,外壁施釉至足底部,釉层凝厚。釉面黑褐色,内,外部满身点点银灰色油滴斑,宛若夜空星辰,晶莹可人。此黑釉油滴碗盏器形质朴典雅,釉面莹润见古,初看似粗,细赏精妙,令人回味无限。 油滴斑为宋代建阳窑创烧的黑釉结晶斑纹,釉面散布着许多具有银灰色金属光泽的小圆点,大小不一,形似油滴而得名,宋代亦称之为“鹧鸪斑”。油滴斑的生成是因为釉中含铁量大,烧成时铁的化合物一群群富集,冷却时局部形成过饱和状态,释出赤铁矿和磁铁矿的晶体所致。一般釉厚处油滴较大,釉薄处油滴较小,这是因为釉层厚和粘度大有利于气泡长大,从而使汽泡周围能聚集更多氧化物的缘故。油滴的形成还与烧成温度有关,这种釉的烧成温度范围很窄,一般不超过20℃左右,如果控制不当,就不能得到满意的瓷器。油滴斑结晶釉一般都施于茶盏上。除福建建阳窑,北方地区的定窑、耀州窑、鹤壁窑、临汾窑也发现过油滴釉瓷器标本。此拍品胎体为较深的紫红色,应为北方窑口的产品。古籍记载黑釉油滴碗“盛茶闪金光,盛水闪银光”,饮茶之余,亦极具意趣。 盏也作琖,是一种比碗小的器皿,宋代文献亦称为瓯或碗。宋代在饮茶过程中增添各种仪式,“斗茶”活动日益盛行,这时饮茶已不再是为了满足简单止渴的需求,而是达官显贵、文人雅士甚至贩夫走卒普遍参与的一种社交行为。为衬托白色的茶汤以便观察茶色,达到评判茶品质高下的目的,黑釉的茶盏最为方便,故而黑釉茶盏一直为斗茶者所偏爱。在宋代文献中关于黑釉茶盏的记载颇多—— 苏轼《宋南屏谦师》:“道人绕出南屏山,来试点茶三昧手。勿惊午盏兔毛斑,打出春瓮鹅儿酒。”(北宋?释惠洪《石门文字禅》卷八,《四部丛刊》本,第11页) 赵佶《大观茶论》:“盏色贵青黑,玉毫条达者为上。”(元?陶宗仪《说郛》卷五十二,中国书店,1986年,第677页) 杨万里《诚斋集》:“鹰爪新茶蟹眼汤,松风鸣雪兔毫霜。”(南宋?杨万里《诚斋集》卷二,《四部丛刊》本,第7页) 上述诗文中所述茶盏绝大多数是建窑产品。建窑,即建州窑,位于福建省建阳市水吉镇的后井、池中村一带,唐宋时期隶属建州,故称建窑。建窑创烧于晚唐,繁荣于两宋,是两宋时期生产黑釉茶盏最重要的瓷窑,目前已发现窑址众多。其所烧茶盏在宋代独步天下,甚至可以说对当时所有生产黑釉茶盏的窑场都有较为深远的影响,生产供斗茶之用的茶盏是目前所见品质最高的。 当时,生产黑釉瓷的瓷窑远不止建窑,其他诸如定窑、鹤壁窑、临汾窑、吉州窑都有大量生产。-------------------------------------------Finely Chinese Porcelain Bowl Huairen kiln oil droplet. Huairen kiln oil droplet in Song dynasty: size: height: 6cm, diameter: 10.8cm. This calyx is open, deep abdomen, abdominal wall arcs, bent. Bearing under the small circle foot, foot wall wider, rotary cut neat, modeling composed atmosphere. The walls are thick and the soil is purplish red. Outer cover black glaze, inner wall full glaze, outer wall glaze to the bottom, thick glaze layer. Glazed black brown, inside, outside covered with silver gray oil dripping spots, like stars in the night sky, crystal but people. This black glaze oil drops bowl shape plain elegance, glazed jade-like runjian ancient, at the beginning of the seemingly coarse, fine appreciation of exquisite, memorable infinite. The oil droplet pattern is the black glaze crystal pattern created and fired by jianyang kiln in song dynasty, and the glaze surface is dotted with many small dots with silver gray metallic luster, different sizes, and the shape looks like oil droplet, hence the name, which is also called "partridge pattern" in song dynasty. The formation of oil droplet spots is due to the high iron content in the glaze, and the enrichment of iron compounds in groups when fired, and the formation of oversaturated state when cooled, and the release of hematite and magnetite crystals. Generally, the oil droplets at the thick glaze are larger, while the oil droplets at the thin glaze are smaller. This is because the thick glaze and high viscosity are conducive to the growth of bubbles, so that more oxides can be gathered around the bubbles. The formation of oil droplets is associated with sintering temperature, the glaze firing temperature range is very narrow, generally no more than 20 ℃ or so, if the improper control, can't get a satisfactory porcelain. Oil droplet crystal glaze is generally applied on the tea cup. In addition to jianyang kiln in fujian, oil-drop glazed porcelain specimens have also been found in dingyao kiln, yaozhou kiln, hebi kiln and linfen kiln in northern China. The body of this lot is deep purplish red, which is the product of northern kiln. It is recorded in ancient books that the black glaze oil drop bowl "contains tea with golden light and water with silver light". Besides drinking tea, it is also very interesting. Light also will be 琖, is a kind of bowl of small vessel, the song dynasty literature also called ou or bowl. In the song dynasty, various rituals were added in the process of tea drinking, and "tea fighting" became increasingly popular. At this time, tea drinking was no longer to satisfy the simple thirst demand, but a kind of social behavior generally participated by dignitaries, scholars and even peddlers. In order to set off the white tea soup so as to observe the color of tea and judge the quality of tea, the black-glazed tea cup is the most convenient. Therefore, the black-glazed tea cup has always been favored by tea fighters. There are many records about black glazed tea cups in the literature of song dynasty Su shi "song nanping modest teacher" : "Taoist people around nanping mountain, to pilot the tea samadhi hand. Don't scare the noon lantern rabbit hair spot, play spring urn goose son wine." (shi huihong, northern song dynasty, shimen writing zen, vol. 8, the four books series, p. 11) Ji-ji zhao, "on the great view of tea" : "the color of the wine is expensive, and the jade is green and black." (yuan ? TaoZongYi said Fu volume fifty-two, China bookstore, 1986, p. 677) Yang wanli "cheng zhai ji" : "eagle claw new tea crab eye soup, pine wind sound snow rabbit hair cream. The tea cups mentioned in the above poems are mostly products of kiln construction. Jian-kiln, namely jian-zhou kiln, is located in the area of houjing and chizhong village, shuiji town, jianyang city, fujian province. The kiln was built in the late tang dynasty and flourished in the song dynasty. The tea brewed in it was unique in the song dynasty, and even had a profound influence on all the kilns producing black-glazed tea brewed in that time. The tea brewed for tea fighting was of the highest quality seen at present. At that time, the production of black glaze porcelain kilns far more than building kilns, other kilns such as dingyao, hebi kiln, linfen kiln, jizhou kiln have a large number of production.
