If the smoothness of the inner surface of the sagger is increased in the process of firing the ceramic artwork, and the sagger is glazed on the inner surface to be subjected to kiln transformation together with the ceramic artwork, the sagger is beneficial to embodying the artistic value. If the sagger is fired as an artwork, the sagger can be used as the artwork, and can be sold and used together with the artwork fired together with the artwork under the same environment, so that the firing cost is obviously reduced due to the fact that one more artwork is added, but the sagger is required to be replaced by materials, the strength of the sagger at high temperature is further reduced, but the sagger made of the materials cannot be overlapped due to low strength, the sagger can also be fired in the ceramic firing process, the original effect of the sagger cannot be lost, the utilization rate of the sagger can be improved, and the cost is further saved; meanwhile, in the process of burning the ceramic artwork by using the firewood and the coal, how to distinguish the works from the coal is sometimes difficult to distinguish, but the situation that the ceramic artwork is burnt by using the firewood or the coal can be easily judged by observing a trace left on the outer surface of the saggar when the saggar is burnt, so that whether the ceramic artwork is burnt by using the firewood or the coal can be verified by selling the saggar which is burnt together with the ceramic artwork together, the ceramic artwork and the saggar containing the ceramic artwork are burnt together with the same glaze, the saggar artwork can be burnt when the ceramic artwork is burnt, and the products which are subjected to the same kiln change when the saggar artwork is marked by using the kiln change method can be used for distinguishing the works from the works which are burnt by using the firewood and the coal.

1. In order to improve the fire resistance of the saggar, modern scientific technology is rapidly developed in recent years, so that the application field of the kaolin is wider, shadows of the kaolin are formed everywhere, a large amount of kaolin is used as a new material in some high and new technical fields, and the reason that the invention adopts the kadsura kaolin instead of other kaolin is as follows: viscosity thixotropy: viscosity is a characteristic of the fluid's internal resistance to relative flow due to internal friction and is typically measured by a rotational viscometer, using a rotational speed in a kaolin slurry containing 70% solids. The thixotropy refers to the property that the slurry which is thickened into gel and does not flow any more is changed into fluid after being stressed, and is gradually thickened into an original state after being static. Viscosity and thixotropy are related to the mineral composition, particle size and cation type in kaolin, so that the use of the kadsura kaolin in sagger making processes is preferred because of its greater viscosity and thixotropy than other kaolins. The drying property also belongs to one of the characteristics of the kadsura root-knot kaolin, and the drying property refers to the properties of the kaolin pug in the drying process, including drying shrinkage, drying strength, drying sensitivity and the like. In the sagger firing process, the sagger blank is easy to deform or crack due to excessive drying shrinkage. The dry strength refers to the breaking strength of the mud after drying to constant weight. Drying sensitivity refers to the ease with which a tendency to deform and crack may develop when the green body is dried. High sensitivity and easy deformation and cracking in the drying process. The purple cajeput kaolin is very suitable for being used on the saggars, and the properties of drying shrinkage, drying strength and drying sensitivity of the purple cajeput kaolin can meet the requirements of the saggars. Firing shrinkage: the firing shrinkage is a property of shrinkage of a product caused by a series of physicochemical changes (dehydration, decomposition, mullite formation, formation of a glass phase by melting of a fusible impurity, filling of voids between particles, etc.) occurring in a dried kaolin material during firing, and is classified into linear shrinkage and bulk shrinkage. As with the drying shrinkage, the firing shrinkage is too large, which easily causes cracking of the green body. The bakelite pitch kaolin is not large in sintering shrinkage in a sagger process, so that a green body is not easy to crack. The sagger drying strength can also meet the strength requirement of overlapping and stacking all saggers.
2. The quartz is used as a barren raw material, the refractoriness of the saggar can be improved, blank drying can be accelerated in a saggar blank, drying shrinkage and deformation are reduced, the chemical affinity of the quartz is strong at high temperature, the quartz can be combined with other various oxides, the liquid phase viscosity is high at high temperature, and the blank combining capacity can be improved. If a large amount of quartz is mixed in the sagger blank during roasting, the sagger blank undergoes crystal form conversion (three sides → hexagonal), so that the volume expansion and the reverse shrinkage of the sagger blank are generated, and particularly, the sagger blank is combined with the padauk kaolin and the clay to make up gaps between the padauk kaolin and the clay.
3. The white feldspar is a barren raw material like quartz, so that drying shrinkage and deformation can be reduced, the white feldspar is used as a flux substance, the firing temperature of a ceramic product can be reduced, the feldspar has the capacity of melting other substances after being heated to more than 1100 ℃ to form a glass state substance, and particles of kaolin and other porcelain clay can be promoted to be diffused and permeated with each other, so that the generation and the development of mullite crystals of the sagger body are accelerated, the white feldspar is filled among crystal particles after being melted into the glass state, the porosity is remarkably reduced, the gaps are reduced, the sagger body is compact, and the mechanical strength and the electrical performance of the sagger product can be improved. The present invention adopts natural mineral material, white feldspar as main solvent, quartz as cosolvent and alkali stone with high aluminum content to obtain proper Si/Al ratio and raise the yield of sagger.
4. The edible alkali is in the raw materials of the saggar, has low content, and mainly plays a role in flattening and smoothing the surface of the saggar.
5. The clay is a main source of alumina in the sagger blank composition, is a main dependence on the fire resistance of the sagger blank, is rich in plasticity, is used for generating binding capacity to some non-plasticity (feldspar, quartz and the like) in the sagger blank, avoids the defects of deformation and cracking of the sagger blank in the drying process, generates strength, and simultaneously has very fine clay particles, while the particles of non-plasticity raw materials are thick and are mixed to obtain the sagger blank structure with very high stacking density.
The sagger is beneficial to embodying of artistic forms due to the advantages of the raw materials, the glaze of the ceramic blank is similar to that of the inner surface of the sagger in glaze color, the glaze color of the surface of the fired ceramic is similar to that of the inner surface of the sagger, the anti-counterfeiting effect is achieved, the sagger can continue to contain the ceramic and can exist in an independent artwork form, the value of the sagger is improved, the process cost is reduced, and the effect of saving resources is achieved.
