元青花云龙纹玉壶春瓶：拍品尺寸：高：28cm，口径：8.9cm，底径：8cm，腹部宽14cm。拍品来源：早期北美西方人家族 旧藏器。说明: 元，景德镇窑，此玉壶春瓶为元代流行的器型，口部外敞平展，束颈，垂腹重心较低，颈、腹间过渡圆滑流畅，低圈足略向外撇，器型稳重。釉色莹润透明，通体青花云龙纹饰，所绘云龙带有元代典型特有的风格，环蟠器腹，昂首怒视，张口，露舌，圆目，身躯修长，龙爪锋利。绘画用笔粗犷流畅，生动传神。圈足、底部时代特征明显。 参考资料：元代瓷器制造最有代表性的成就是釉下彩技术的广泛应用。所谓釉下彩技术，是在瓷胎上先画出纹饰图案，再施上一层无色透明釉，然后经高温烧制。其优点一是由于可以直接在瓷器上进行绘画，利于创作者的艺术发挥；二是绘上去的图案永不褪色。元代在技术和原料两方面取得了突破，于是创造了以青花和釉里红为代表的新品种。 所谓青花，就是在绘画时使用加入氧化钴成分的颜料，烧成后呈现蓝色花纹的釉下彩瓷器。由于使用钴料，所以具有着色力强、色彩鲜艳的特征，而且在烧制过程中，窑内的气氛变化对其影响较小，烧成可能性较大，并且呈色稳定。由于青花瓷器的色彩符合蒙古统治者和来自西亚、中亚的伊斯兰国家的喜好，所以得以在元代迅速发展，不但在国内广泛流行，而且也成为最受欢迎的外销瓷品种之一。 釉下彩技术，是在器物坯材上先用釉料绘出花纹，再上一层无色透明釉，然后高温烧制。彩色釉被覆盖在一层透明釉之下，故称为釉下彩或釉里彩。若在第一次所施釉中加入钴（Co）的成分，烧成的瓷器呈蓝青色，称为青花瓷，这种工艺在唐宋已使用，但不普遍。到了元代，则大量烧制青花瓷器，因釉料中含钴量的多少不等，加之火候亦有差异，故烧成品的颜色有深有浅。玉壶春瓶的器形前代就有，元代继续流行，但颈部缩短，腹部突出，圈足亦变矮以致近似于平底，增加了稳重感。---------------------------------------------------------------------------------------- Yuan blue and white cloud dragon pattern Yu-hu-chun vase: Lot size: height: 28cm, caliber: 8.9cm, bottom diameter: 8cm, belly width 14cm. Lot source: Early North American Westerners family. Description: Yuan, Jingdezhen kiln, this jade pot spring bottle is popular in the Yuan Dynasty, the mouth is open and flat, the neck and neck are lower, the center of gravity is lower, the transition between the neck and the abdomen is smooth and smooth, and the low circle is slightly outward. The model is stable. The glaze is velvety and transparent, and the whole body is decorated with blue and white dragons. The painted dragon has the unique style of the Yuan Dynasty. It is surrounded by abdomen, glaring at the head, mouth, tongue, round eyes, slender body and sharp claws. The painting pen is rough and smooth, vivid and vivid. The characteristics of the circle foot and the bottom age are obvious. References: The most representative achievement of Yuan Dynasty porcelain manufacturing is the wide application of underglaze technology. The so-called underglaze color technique is to first draw a decorative pattern on the porcelain tire, and then apply a layer of colorless transparent glaze, and then fire it at a high temperature. One of the advantages is that it can be directly painted on porcelain, which is conducive to the artist's artistic performance; the second is that the painted pattern will never fade. In the Yuan Dynasty, breakthroughs were made in both technology and raw materials, and a new variety represented by blue and white glaze was created. The so-called blue-and-white flower is a glazed porcelain with a blue pattern after firing. Because of the use of cobalt material, it has the characteristics of strong coloring power and bright color, and in the process of firing, the change of the atmosphere in the kiln has less influence on it, and the possibility of firing is large, and the color is stable. Since the color of blue and white porcelain conforms to the preferences of Mongolian rulers and Islamic countries from West Asia and Central Asia, it has developed rapidly in the Yuan Dynasty, not only widely popular in China, but also become one of the most popular export porcelain varieties. Under the glaze color technology, the glaze is first painted on the material material, and then a layer of colorless transparent glaze is applied, and then fired at a high temperature. The colored glaze is covered under a layer of transparent glaze, so it is called underglaze or glaze. If the cobalt (Co) component is added to the first glaze, the fired porcelain is blue-blue, called blue-and-white porcelain. This process has been used in Tang and Song Dynasties, but it is not common. In the Yuan Dynasty, a large number of blue-and-white porcelains were fired. Because of the amount of cobalt contained in the glaze, and the difference in heat, the color of the finished product was deep and shallow. The shape of the jade pot spring bottle has been in the predecessor, and the Yuan Dynasty continues to be popular, but the neck is shortened, the abdomen is prominent, and the foot is also shortened to resemble a flat bottom, which increases the sense of stability.
