Pure handmade tea set production process

Pure handmade tea set production process
1. Kneading the clay
The purpose of kneading the clay is to empty the bubbles in the clay material and make the clay material more compact. If this process is missing, it is easy for bubbles to appear in the blank, and the blank is easy to break and deform when it is dried and fired
2. Making the blank
The traditional round ware in Jingdezhen is to make a blank roughly corresponding to the final shape of the ware for use in the later printing of the blank.
3. Printing the blank
The finished rough blank can enter the printing process after a certain period of natural shade drying (it must be naturally shade dried under certain humidity and temperature conditions, and cannot be exposed to the sun. The blank must be placed obliquely on the blank board, not upright. If it is placed upright, cracks may occur at the bottom of the blank). Printing the blank is to make the formed round ware uniform after firing. After the blank is naturally dried, the semi-dry blank is placed on the earthenware mold and patted by hand to make the blank round and even.
4. Sharpening the blank
Sharpening the blank is to fine-process the printed blank to make it more smooth and round.
5. Swinging the inner glaze
When making round vessels, if there is no decoration inside the vessel, you need to apply the inner glaze first. The glaze on the outside of the vessel is the second dipping glaze in the later stage. Glaze is a thin layer of glass attached to the surface of the ceramic body, which has similar physical and chemical properties to glass. Glaze is generally made of quartz, feldspar, clay, etc. The methods of ceramic glazing include: spraying, blowing, dipping, pouring, swinging, etc. We use the traditional swinging glaze method for the inner glaze (the glaze inside the vessel) and the bottom glaze (the glaze on the bottom of the vessel), and the dipping glaze method for the outer glaze.
6. Painting the blank
After the inner glaze is washed, the painting process can begin.
The blue and white material used for painting the blank needs to be ground for a long time in advance, and the formula is a secret of each studio. The charm of blue and white porcelain is like the status of freehand ink landscape in Chinese traditional painting. The beauty of blue and white porcelain lies not only in the fine painting skills, but also in the beautiful and delicate layers of the traditional Chinese ink landscape with the texture and dyeing methods, and all of this comes from the process of mixing water.
7. Applying external glaze
The finished porcelain blank needs to undergo a second glazing process. At this time, the bottom foot of the cup has not yet been formed. The glazing method requires the master to have a comprehensive understanding and grasp of the blank, glaze and the expectations of the porcelain. The length of time the porcelain blank is immersed in the glaze directly affects the appearance of the porcelain after firing                                        8. Digging the bottom footAfter the porcelain blank is glazed on the outside, after the glaze surface is naturally dry, the process of digging the bottom foot can be entered. Since we are making glazed-footed objects, we need to leave the outermost circle of the bottom foot blank when digging the bottom foot, and the outer circle must be kept basically consistent, which requires strong control ability and skills
9. Write the bottom style and apply the bottom glaze
10. Install the glazed foot
The glazed foot, in its initial state, is a small round mud cake made on the pottery wheel. After drying, the corresponding shape is again spun on the pottery wheel, corresponding to each cup one by one.
The stilt firing process with glazed feet was first seen in the official kiln firing palace porcelain. The feet of the porcelain vessels fired with glazed feet are fully glazed, which is beautiful and smooth without scratching the surface of the furniture. However, due to the complexity and difficulty of this process, the modern ceramic industry only uses this process to fire precious high-end porcelain.
11. Full kiln, firing kiln
The reasonable distribution of the porcelain blanks to be fired in the kiln body is called a full kiln. When the kiln is full, it is necessary to arrange the blanks reasonably according to the size of the kiln structure and the size of all the blanks to be fired, and leave a reasonable fire channel and flue, otherwise it will affect the atmosphere in the kiln during firing and cause firing failure.
