The mullite stoneware is divided into small utensils and large utensils. Today, Xiao Bian takes us to understand the compositional structure of the skeletons. I hope that the introduction of the Xiaobian can help us understand more about the mullet.

The small device consists of a wall (also known as a dome) and a base. The process of making a wall is roughly as follows: first take a number of special bamboo pieces, use a string to pass through the direction of the thickness of the bamboo, and then put it upside down, and put the two ends together to form a circular cylinder, and the inside is fixed with an iron circle. The outside is tied with a rope. Then apply the clay on the outer wall of the cylinder. When it is applied to a certain thickness, wipe the outside with a cloth and then use a piece of iron to shape and reshape it. After finishing, remove the iron ring inside the barrel, remove the barrel from the inner surface, then smooth the inner wall and shape. After the wall is well-made, move it to his place to dry it. The process of making the terrestrial 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 concrete wall, and place the mud in the enemy's circle with the foot, so that the mud can evenly fill in all parts of the circle. Then put a ball of mud in the center and tap it tightly. When the wall and the bottom of the raft are properly dried, the raft shall be smashed and placed on top of the raft, whereafter the joint will be flattened.

The large system consists of straight walls and inclined walls. The method of making a straight wall is roughly the same as that of making a wall. The method of manufacturing the slanted wall is similar to that of the porcelain green body, but because the niobium mud particles are relatively coarse, it is necessary to carry out the water work during the plastic repair. After the straight wall and the inclined wall are made, they are adhered to each other with a mortar. The method of bonding is basically the same as the adhesive method of small devices. The prepared blank is still a green body (commonly known as soil rake). The soil rake can not be used for burning porcelain. It is only necessary to plate (ie, roast) the soil ridges into a ring of enamel, and then use it to burn the porcelain. Billet.

The mullite stoneware is divided into small utensils and large utensils. The above is the introduction of the mullite stoneware. I hope that the introduction of the Xiaobian can help us to understand the mullite stone more comprehensively.
