祭紅釉是景德鎮的陶工在明宣德時期創燒的著名紅釉品種，色似初凝的雞血，深沉安定，瑩潤均勻，釉中無龜裂紋理，因祭紅器作祭祀郊壇之用，故名。祭紅始創于明永樂、宣德年間。在古時皇室常以它作祭器，人們在配制祭紅釉料時，往往將黃金、珊瑚、瑪瑙、玉石等珍貴之物摻入釉料中，真可謂不惜工本。即使這樣，也往往燒制不出好的成品。由于祭紅釉瓷器歷來難燒，因此它比其它色釉更為名貴。河南的鈞瓷有“十窯九不成”的說法，表明紅釉是一種極難掌握的燒成技術。而景德鎮的祭紅比鈞紅還要難燒得多，按民間的說法，叫“千窯一寶”，也就是上百爐的窯火中，才能得到一、兩件祭紅。
The red glaze is a famous red glaze variety created by the pottery workers in Jingdezhen during the Ming Xuande period. The color is like the initial chicken blood, deep and stable, even and smooth, and there is no crack texture in the glaze. Sacrifice red began in Ming Yongle, Xuande years. In ancient times, the royal family often used it as a sacrificial device, people in the preparation of red glaze, often gold, coral, agate, jade and other precious things into the glaze, really at the cost of work. Even so, often can not burn out good finished products. Because red glaze porcelain has always been difficult to burn, it is more expensive than other colored glaze. Henan Jun porcelain has a "ten kilns nine fail" statement, indicating red Glaze is a very difficult to master firing technology. And Jingdezhen's sacrifice red than Junhong is much more difficult to burn, according to the folk saying, called "thousand kilns and one treasure ", that is, hundreds of kiln fire, can get one or two offerings of red.
祭紅的特點之一是沒有裂紋，熱穩定性較好，不但能夠裝飾陳設瓷，而 且還能裝飾餐具，茶具、酒具等坯體很薄的日用瓷。祭紅的這一特點，就使它在配方和化學組成要求祭紅釉的膨脹系數比較小。堿金屬鉀、鈉的氧化物在釉料中含量的多少是使銅呈現紅色的主要因素，所以祭紅釉料中這樣膨脹系數大的氧化物較少。氧化鉀和氧化鈉的膨脹系數較大，在釉料中的含量達到一定數量，就會使釉的膨脹系數增大而出現裂紋，含量再多就會出現更多的裂紋，成為紋片釉。紋片釉如鈞紅和郎窯紅遍身布滿裂紋，制品極易破碎，故此，采用加厚坯胎的方法來防止制品破裂。
One of the characteristics of sacrifice red is that there are no cracks, good thermal stability, not only can decorate the porcelain, but also can decorate tableware, tea sets, wine utensils and other billet very thin daily porcelain. This characteristic of sacrificial red makes it smaller in formula and chemical composition. The content of alkali metal potassium and sodium oxide in glaze is the main factor to make copper appear red, so the oxide with large expansion coefficient in red glaze is less. If the expansion coefficient of potassium oxide and sodium oxide is large, the content of glaze will increase and crack, and more cracks will occur Stripe, become stripe glaze. Striped glaze such as Junhong and Langyao red body covered with cracks, products are easy to break, therefore, the method of thickening billet to prevent product rupture.
祭紅的特點之二是釉面不流。因為釉面不流，故而不脫口，口項與底壩才能出現美麗的燈草邊；因為釉面不流，故而壩子不粘墊餅，不需要磨壩子，故而坯胎可以較薄。也因為釉面不流，說明釉料的熔融和玻化程度不夠；可以認為，祭紅釉在它坯體成熟溫度時，沒有得到充分熔融，它的特點與燒成條件使它不能達到像玻璃一樣的均一組織，而是玻璃質與晶體的混合體。
The second characteristic of sacrifice red is that glaze does not flow. Because the glaze does not flow, so it is not easy, the mouth item and the bottom dam can appear the beautiful lamp grass edge; because the glaze does not flow, therefore the dam does not stick to the cushion cake, does not need to grind the dam, therefore the billet can be thinner. Because the glaze does not flow, it shows that the melting and vitrification degree of glaze is not enough; it can be considered that the red glaze is not fully melted at the mature temperature of its billet, and its characteristics and firing conditions make it unable to achieve homogeneous tissue like glass. It is a mixture of vitreous and crystal.
此件藏品祭紅釉留白龍紋八菱瓶，高：42.6cm，口徑：11.5cm，底徑：13.7cm其釉面紅不刺目，鮮而不過，釉面不流，裂紋不出， 釉色深沉，釉面光潤，釉中無龜裂紋理，不甚透明，不流釉，不脫口，不開片。眾所周知的就是郎窯紅比鈞紅成品率低，而祭紅比郎窯紅的成品率就更低，更難燒，因此祭紅釉的價值也更高，市面上也更罕見，如果你有幸遇見，一定要抓住機會收藏。
This collection of red glaze white dragon grain Baling bottle, high :42.6 cm, caliber :11.5 cm, bottom diameter :13.7 cm its glaze red not glaring, fresh but, glaze does not flow, crack, glaze color deep, glaze smooth, glaze without crack texture, not very transparent, do not flow glaze, do not open. It is well known that Lang kiln red is lower than Jun red finished product rate, and sacrifice red than Lang kiln red finished product rate is lower, more difficult to burn, so the value of red glaze is higher, the market is also more rare, if you are lucky to meet, Be sure to seize the opportunity to collect.
