Make ceramics easier︱”Mirror Decal Yellow”
Mix finer pottery clay or porcelain clay with water into a slurry and apply it on the pottery or porcelain body. A thin layer of color paste, either white, red or gray, will be left on the surface of the object. This color paste, In ceramic technology, it is called “pottery coat”, also called “cosmetic clay”, “decorative clay”, and “baby glaze”
Cosmetic clay decoration is one of the typical decorative techniques at kiln entrances in northern my country, represented by Xing kiln. It started in the Northern Dynasties. It was originally used to change the color of the carcass and enhance the whiteness and brightness of the porcelain. White was used before glazing. The technique of using makeup soil to protect the fetus was still used until the Song and Yuan Dynasties
The “wedding dress” of pottery: cosmetic clay
Common ceramics are mostly made of clay covered with glaze and fired. However, the clay in the north is rougher, and the feel and appearance are greatly reduced after firing. Therefore, smart ancient pottery craftsmen invented cosmetic clay mud to solve this problem.
▲ Makeup clay + carved decoration
Cosmetic clay mud has a fine texture, uniform color, strong covering power, and high fire resistance. It also has three major functions of concealing, beautifying, and repairing leaks. It ensures your appearance after use.
Concealer: Apply the cosmetic clay slurry evenly on the surface of a body with a rough texture or a dark color. After glazing and firing, the rough body surface becomes smooth and flat, and the color difference is covered, making the glaze surface more beautiful, bright and soft. Gentle
Beautification: Add other glaze colors to the cosmetic clay, apply it to the surface of the body, and then combine it with flower picking and painted 粲 techniques to form a rich and diverse natural mineral decorative effect and enhance the weathering resistance.
Leakage repair: The fine mud can also prevent the green body from absorbing a large amount of glaze and burning cracks, and fill the pores in the green body to make its surface more dense.

With the development of human civilization, porcelain making technology and decoration techniques have continued to mature, and cosmetic clay has gradually fallen out of favor. However, cosmetic soil supports many starting points of ceramic craft civilization. When we praise the achievements of ceramic art, we should not forget the contribution of cosmetic soil.
Today, let us once again pay tribute to tradition and learn the ancient decorative technique of applying clay and flowers↓↓↓
▲ Makeup soil + carving effect of the work
It’s simply not too perfect! Is there any
The big move is here↓↓↓
Material preparation:
● Repaired, 70% dry mud brick
● 1 sponge, 2 carving knives, 1 brush
● High white mud and mineral raw materials such as feldspar and quartz
Production steps:
Step 1: Use a sponge to wipe off the dust on the body
Step 2: Prepare cosmetic soil, and add feldspar, quartz and other raw materials into the high-white mud in a certain proportion (function: to cover up the small holes and variegated colors on the surface of the body to adjust the shrinkage and expansion coefficient of the cosmetic soil, And increase the hardness of the makeup soil)
Step 3: Apply the prepared mud to the body by swamping, dipping, etc.
Step 4: After drying, use a pen to mark the makeup soil, and use a tool to remove the excess white makeup soil to expose the carcass to form a black and white contrast
Step 5: Apply transparent glaze and fire
Notes: The particle fineness of the cosmetic soil should be smaller than the body but larger than the glaze, and the suspension should be good to ensure that it can adhere well to the body before and after firing.
