Chapter 44: Jianzhan (1)
When Lan Eucalyptus was tidying up at home on the weekend, he found a beautifully carved wooden box in the cabinet, and Lan Eucalyptus wiped the dust off the lid with a rag, held the box on the desk, and carefully opened the wooden box, only to see a silver rabbit lying in the box.
This silver rabbit is built with a strong metallic texture, and it has a strong sense of embossing, shining silver under the light. The warm and moist jade shadow, like a beautiful woman in the mirror, although difficult to touch, but beautiful and delicious, has a unique aesthetic interest, beautiful and simple.
A simple and elegant "Jianzhan" is to make full use of the glaze material, the inherent potential beauty expressed, it gives people not only the spectacular beauty of nature and the universe, but also the vision and touch can not be perceived, a kind of beauty that can only be felt by the heart. The production process of Jianyao Jianzhan harmoniously unifies the smooth, concise and practical shape, the glaze color and the ingenious unique markings in the treasures of the kiln, so that it undoubtedly stands at the pinnacle of ancient Chinese black glazed porcelain manufacturing and becomes a poetic porcelain altar.
The rabbit is the representative glaze color of the building lamp, divided into silver (including silver blue), blue, brown and other colors, among which the silver rabbit is the rarest. Song Huizong once approved the royal approval: "The color is noble and blue, and the jade is on the top." Among them: "jade hair" refers to the silver rabbit hair.
As the most popular variety of Jianzhan, the rabbit has repeatedly proved its lofty status with archaeological achievements, famous products and historical documents. "Tea Ware Tuzan" even paints one of the twelve tea sets directly as a rabbit teacup, and its iconic status is undoubted.
Why is Rabbit Hair called Rabbit Hair? The reason is that the crystallization pattern of the rabbit is a uniform and fine filamentous vein stripe in the black glaze, which is shaped like the hair of a rabbit, hence the name.
The wavy silver quill in the hand of the blue eucalyptus looks like the ripples on the water surface, twisting and turning, changing with the water, with strong contrast, thick carcass and good heat preservation. In addition, the glaze is as smooth as jade, and the rabbit hair lines radiate outward, which is extremely beautiful. It is an excellent variety of silver quill, which is rare in the market.
Blue eucalyptus remembers that her mother said that among the various glaze colors in the rabbit milligraph, the silver rabbit millimeter markings are the most precious, and the difficulty of firing is also the greatest. In the process of high-temperature firing, the carbon monoxide produced is used as a reducing agent to undergo a complex reduction reaction with the ferric iron in the glaze water, thereby precipitating elemental iron, which rises to the surface of the glaze layer and then bursts and releases with the bubbles generated in the glaze boiling, and then flows down the melted glaze water, thus forming a strip pattern.
However, the spots formed by the bursting of bubbles are very easy to disperse, and the reducing atmosphere in the kiln will quickly convert the trivalent iron into bivalent iron, which will quickly integrate into the glaze and make the markings disappear, so these markings last for a very short time, especially the firing silver markings, if the trivalent iron is too high, the markings will be gray and dirty, if the bivalent iron is too high, the markings will disappear or even disappear.
The hardships of firing the building lamp can be imagined, so the best building lamp is extremely precious. For example, the top silver oil droplets, at a glance, you can get a glimpse of the charm of the silver oil droplets of the Song Dynasty, and the details can also stand up to scrutiny, taking into account the color of the markings (elegant and pure silver), the texture of the markings (strong metallic three-dimensionality), the shape of the markings (rounded and not deformed), the arrangement of the markings (evenly distributed, dense and compact), and the vitrification quality (good vitrification, narrow dry mouth).
