Northern Song Dynasty andSouthern Song DynastyPorcelainThere is a clear difference in the lap foot at the bottom. Fired in the early and middle Northern Song DynastyPorcelain, the lap foot at the bottom shows a trend of getting shorter and shorter. This high hoop foot design not only increasesPorcelainstability, but also easy for users to access. And in the late Northern Song Dynasty andSouthern Song DynastyDuring the period, the hoop feet of porcelain were mostly solid and flat-bottomed. This design makes:PorcelainIt is more stable and reduces the difficulty of firing.
Expansion: Lap foot is more than thatPorcelainThe bottom structure, stillPorcelainAn important part of the production process. InPorcelainDuring the firing process, the craftsmen need to place the semi-finished product on a turntable and scrape off the excess glaze along the hoop with their hands or tools. In this way,PorcelainThe bottom is smoother and easier to create delicate ornaments.
Northern Song DynastyPorcelainwithSouthern Song DynastyPorcelainThere are also obvious differences in the engraving process. Northern Song DynastyPorcelainThe scribing process is generally inferiorSouthern Song DynastyPeriodPorcelain。toLongquan kilnPorcelainFor example, the Northern Song DynastyLongquan kilnPorcelainThe ornamentation on it is mostly lotus petalsPlum blossoms, water waves and other kinds of ornamentation, the lines are thicker, and the process is relatively simple. And here it isSouthern Song DynastyPeriodLongquan kilnPorcelain, the ornamental carving is more delicate and exquisite. These works incorporate the best of celadon technology in form, decoration and technique, which is why they produce such exquisite works.
Extensions:PorcelainThe ornamentation on it is not only decorative, but also represents the society of the timeCultureand an embodiment of aesthetic concepts. The difference in ornamentation not only reflects the changes of the times and people's aesthetic preferences, but also reflects the innovation and improvement of craftsmanship of craftsmen. PorcelainThe ornamentation on can beNaturecan also be a story of characters, each of which carries a piece of history andCultureof memory.
Northern Song DynastyPorcelainwithSouthern Song DynastyPorcelainThere is also a difference on the bottom tyre. Northern Song DynastyPorcelainThe bottom tire is heavierPorcelainThe inner walls are also thicker. In contrast,Southern Song DynastyPeriodPorcelainThe carcass is thinner, but the carcass is a little rougher. This may have been due to the raw materials and firing technology of the time.
Expansion: The bottom tire of porcelain is more than thatPorcelaininfrastructure, but also directly impactedPorcelainoverall quality. The thickness and texture of the bottom tire are determinedPorcelainsturdiness and hand comfort. A good bottom tire can makePorcelainIt is more durable and can improvePorcelainornamental value.
Northern Song Dynasty andSouthern Song DynastyofPorcelainThere are also differences in the production process. In the early Northern Song Dynasty, craftsmen used the back-firing method for firing, that is, the porcelain embryo was put into a sagger for firing. In the middle of the Northern Song Dynasty, people began to use a firing method called "overburning". This method requires placing the porcelain embryo in a sagger, and many pieces can be fired at oncePorcelain。However, before firing, the glaze on the rim of the mouth needs to be scraped off in advance. In this way,PorcelainThe rim of the mouth is exposed, often wrapped in metal to disguise this disadvantage.
Extensions:PorcelainThe firing process isPorcelainA unique feature, tooPorcelainA key link in the production. The temperature control during the firing process, the ratio of the glaze and the firing time all have a significant impact on the quality of the finished product. Craftsmen need to be basedPorcelainThe type and design requirements are precisely mastered to ensure the technical details of firingPorcelainThe quality is excellent.
Northern Song Dynasty andSouthern Song DynastyofPorcelainThere are also certain differences at the bottom, which are mainly reflected in the use of support nails. Northern Song DynastyPorcelainExceptRu kilnIn addition, most of them are fired with gaskets or mat cakes. WhileSouthern Song DynastyofPorcelain, most of them will be equipped with a nail at the bottom. PorcelainIt is more common to have more nails at the bottom, and this is most likely the caseSouthern Song Dynastyperiod of firingPorcelain
Extension: What is the role of the studs?In fact, the nail is an important tool in the firing process. InPorcelainDuring the firing process, the craftsmen need to place the porcelain embryo on the nail to avoid the firing processPorcelainDeformed, deformed, or collapsed. The use of the nails is not only convenientPorcelainThe firing can also be guaranteedPorcelainStability during firing.
Through the above five elements, we can distinguish the Northern Song Dynasty and the Northern Song Dynasty relatively clearlySouthern Song DynastyPorcelain。Northern Song DynastyPorcelainThe bottom of the ring foot is higher, the carving process is relatively simple, the bottom tire is heavier, and the back firing method is adoptedWhileSouthern Song DynastyPorcelainThe bottom of the ring foot is low, the carving process is delicate, the bottom tire is light and thin, and it is fired by the overfiring method, and there are often nails. These differences not only reflect the technical characteristics of different periods, but also reflect the social and social conditions of the timeCultureof the vicissitudes.
