祭红釉是景德镇的陶工在明宣德时期创烧的著名红釉品种,色似初凝的鸡血,深沉安定,莹润均匀,釉中无龟裂纹理,因祭红器作祭祀郊坛之用,故名。

霁红釉天球瓶

精品推荐—霁红釉天球瓶

天球瓶是一种瓷器造型,创烧于明代永乐、宣德年间的景德镇窑,青花天球瓶、粉彩天球瓶、紫釉天球瓶、郎窑红天球瓶、五彩天球瓶。永乐朝开始成为观赏式瓶,宣德年间较为流行。瓶形为小口、直颈、丰肩、假圈足、砂底微凹。

祭红的特点之一是没有裂纹,热稳定性较好,不但能够装饰陈设瓷,而且还能装饰餐具,茶具、酒具等坯体很薄的日用瓷。祭红的这一特点,就使它在配方和化学组成要求祭红釉的膨胀系数比较小。碱金属钾、钠的氧化物在釉料中含量的多少是使铜呈现红色的主要因素,所以祭红釉料中这样膨胀系数大的氧化物较少。氧化钾氧化钠的膨胀系数较大,在釉料中的含量达到一定数量,就会使釉的膨胀系数增大而出现裂纹,含量再多就会出现更多的裂纹,成为纹片釉。纹片釉如钧红郎窑红遍身布满裂纹,制品极易破碎,故此,采用加厚坯胎的方法来防止制品破裂。历史以来,铜红釉的制品(包括钧红、郎窑红、玫瑰紫、宋均花釉以及各种窑变花釉),除祭红和美人醉外,它们的坯体都很厚,十分笨重,只适宜装饰厚胎的陈设瓷。正如前面所讲,由于祭红不允许有裂纹出现,就限制了有利于铜红呈色而膨胀系数较大的氧化钾和氧化钠的含量,相应就增加了不利于铜红呈色而膨胀系数小的其它氧化物的含量。故此,配制美丽的祭红釉就显得比钧红、郎窑红多了一个相互矛盾的难题。

祭红的特点之二是釉面不流。因为釉面不流,故而不脱口,口项与底坝才能出现美丽的灯草边;因为釉面不流,故而坝子不粘垫饼,不需要磨坝子,故而坯胎可以较薄。也因为釉面不流,说明釉料的熔融和玻化程度不够;可以认为,祭红釉在它坯体成熟温度时,没有得到充分熔融,它的特点与烧成条件使它不能达到像玻璃一样的均一组织,而是玻璃质与晶体的混合体。有人用偏光显微镜在无上偏光镜(分析镜)的情况下,进行薄片观察所证实。观察发现釉层中有大小不等的气泡,除此之外,未见异物,即使放大900倍也未发现可见的晶体存在。据文献介绍,有人对铜红玻璃进行了研究,摸索出了铜红玻璃呈色的规律,认为铜红呈色机理是玻璃熔体化学热力学与过饱和熔体相分离的动力学问题。铜红釉与钢红玻璃的呈色机理应该是一致的,呈色条件也应该相似。要形成最佳的铜红釉,它不但与釉科的组成有关而且还要求充分的还原气氛,适当的窑内压力和使釉料充分熔融与玻化的烧成温度。这几个条件都能充分的满足,就能制得最佳的铜红釉制晶。因要求祭红不流,故此烧成温度比钧红郎窑红低45℃至50℃,熔融和玻化程度,也不如钧红和郎窑红。故此,祭红比钧红,郎窑红又多出一个困难因素。

这件霁红釉天球瓶,为鸡血红,釉色有如初凝的鸡血,表面浮雕龙云纹,金釉装饰,富贵华丽,这在古代任何红釉都是比不了的,故而深受宫廷所喜爱,历来为红瓷之最,整个天球瓶无磕无残,品相完美,具有极高的收藏价值。

英文翻译:Sacrificial red glaze is a famous red glaze created by potters in Jingdezhen during the Xuande period of the Ming Dynasty. It is similar in color to chicken blood at the beginning of coagulation, deep and stable, smooth and uniform, and there is no cracking texture in the glaze. It is named because the sacrificial red ware is used for sacrificing to the suburb altar.

Tiantian vase is a kind of porcelain shape, created in the Ming Dynasty Yongle, Xuande years of Jingdezhen kiln, blue and white tiantian vase, pastel tiantian vase, purple glaze tiantian vase, Lang kiln red tiantian vase, colorful tiantian vase. The Yongle dynasty began to become ornamental bottles, more popular during the Xuande period. Bottle shape for small mouth, straight neck, full shoulder, false circle foot, sand bottom slightly concave.

One of the characteristics of offering red is that there is no crack, good thermal stability, not only can decorate display porcelain, but also can decorate tableware, tea, wine and other very thin body of daily porcelain. This feature of the red glaze makes it in the formula and chemical composition requirements of the red glaze expansion coefficient is relatively small. The content of alkali metal potassium and sodium oxides in glaze is the main factor that makes copper appear red, so there are fewer oxides with large expansion coefficient in red glaze. The expansion coefficient of potassium oxide and sodium oxide is large, and when the content in the glaze reaches a certain amount, it will increase the expansion coefficient of the glaze and crack, and more content will appear more cracks, becoming a flake glaze. Flake glazes such as Jun red and Lang kiln red are full of cracks all over the body, and the products are easily broken. Therefore, the method of thickening the blank tire is adopted to prevent the products from breaking. Historically, copper red glaze products (including Jun red, Lang kiln red, rose purple, Song Junhua glaze and all kinds of kiln glaze), in addition to offering red and beauty drunk, their body is very thick, very heavy, only suitable for decoration of thick furnishing porcelain. As mentioned above, since no cracks are allowed in the red, the content of potassium oxide and sodium oxide, which are favorable for the color of copper red and have a large expansion coefficient, is limited, and the content of other oxides, which are unfavorable for the color of copper red and have a small expansion coefficient, is correspondingly increased. Therefore, the preparation of beautiful sacrifice red glaze appears to be more than jun red, Lang yao red a contradictory problem.

The second characteristic of offering red is that glaze does not flow. Because the glaze does not flow, so it does not blurt out, the mouth and the bottom dam can appear beautiful lampgrass edge; Because the glaze does not flow, so bazi do not stick to the cake, do not need to grind the bazi, so the blank tire can be thinner. Also because the glaze does not flow, that the melting and vitrification of the glaze is not enough; It can be considered that the red glaze in its body mature temperature, not enough melting, its characteristics and firing conditions so that it can not achieve the same uniform structure as glass, but a mixture of glass and crystal. This has been confirmed by thin section observations under a polarizing microscope with no polarizer (analytical mirror). There were bubbles of different sizes in the glaze layer. Besides, no foreign bodies were observed, and no visible crystals were found even at 900 times magnification. According to the literature, some people have studied the copper-red glass and found out the law of copper-red glass color. It is believed that the mechanism of copper-red color is a dynamic problem of chemical thermodynamics of glass melt and phase separation of supersaturated melt. Copper red glaze and steel red glass color mechanism should be the same, color conditions should be similar. To form the best copper red glaze, it is not only related to the composition of the glaze family but also requires sufficient reducing atmosphere, appropriate kiln pressure and firing temperature to make the glaze melt and vitrification. These conditions can be fully satisfied, can produce the best copper red glaze crystal. Due to the requirement of offering red not flow, so the firing temperature is 45℃ to 50℃ lower than Jun red and Lang kiln red, melting and glass, as jun red and Lang kiln red. Therefore, offering red than jun red, Lang Kiln red and a more difficult factor.

This ji red glaze celestial globe bottle, for the chicken blood red, glaze color as the initial coagulation of the chicken blood, surface relief dragon cloud pattern, gold glaze decoration, riches and honor, which in ancient times any red glaze is better than, so loved by the palace, has always been the most red porcelain, the whole Celestial globe bottle without knock no residue, perfect appearance, has a high collection value.
