                Do you know saggers?


                Firing saggers into ceramics can not only increase firing load, but also prevent the products from sticking and increase the yield, but also have certain thermal conductivity and thermal stability, which can guarantee the quality of ceramics. Saggers vary in shape according to the wares. China's dragon hill culture period fired eggshell black pottery, has used a special sagger. Two saggers, the earliest known saggers, have been collected from the yangjiazi site of zhucheng city, shandong province, and fired into dragon mountain culture eggshell pottery. Saggers, found in later generations, are mainly used for holding porcelain, and have been found in xiang kiln in sui dynasty.


                Saggers are saggers of various specifications made of refractory clay and fired at high temperature. Various ceramic slabs must be loaded into saggers before being fired in kiln.


                Saggers are composed of casing wall (also known as casing ring) and casing bottom. The process of making the wall of the box is roughly as follows: first, take several pieces of specially made bamboo slices, pass through them with thin rope along the thickness direction of the bamboo slices, then place them vertically, close the two ends into a ring cylinder, fix the inner end with an iron circle, and tie the outer end with a rope. Then apply the mud to the outer wall of the cylinder. When the mud is applied to a certain thickness, dip the cloth in the water and wipe the outer wall flat. After finishing, remove the inner iron ring of the ring cylinder, shrink the ring cylinder from the inner surface, then wipe out the inner wall and reshape. When the casing wall is finished, move it to another place to air. The process of making the bottom of the stem is roughly as follows: first, take a special iron ring whose diameter is equal to or slightly larger than the outer diameter of the wall of the box, step on the mud in the box with your feet, and make the mud in the box evenly fill all parts of the circle. Then put a lump of mud in the center of the box and pat it tight. After the bottom of the box is made, let it cool a little. When the wall and bottom of the box are moderately dry, dip the wall edge of the box into the pulp, sit it on the bottom of the box, and then trim and level the adhesion.


                Saggers are composed of straight wall and oblique wall. The method of making straight wall is roughly the same as that of making small box wall. The method of making inclined wall is similar to that of porcelain billet drawing. However, due to the coarse mud particles in the box, it is necessary to carry water during finishing and shaping. After the straight wall and the inclined wall are made, they are bonded together with the box pulp. The bonding method is basically the same as that of sagger.


                The finished pot billet belongs to the green billet (commonly known as the soil box), and the soil box cannot be used for porcelain firing billet. Only after the soil box is plated (that is, roasted) into a ring box (cooked box), can it be used for porcelain firing billet.


                Saggers used in the production of industrial refractories include mullite, corundum mullite, alumina and so on.
