Inlaying process of Nixing pottery

Abstract

The invention discloses an inlaying process of Nixing pottery. The inlaying process comprises the following steps: (1) preparing a preform body; (2) preparing a color clay material; (3) preparing mixed slurry: mixing the color clay material and the preform body to obtain a mixture, and charging water in the mixture to obtain the mixed slurry; (4) forming a green body; (5) engraving and inlaying, namely drawing a picture on the green body, wrapping an opening and a part, which is not engraved currently, of the green body with a plastic film, carving out grooves on two side edges along ink marks for the engraving part, smearing a layer of mixed slurry into the grooves, inlaying the color clay material into the grooves, leveling the color clay material, slightly drying the color clay material until the color clay material is concaved, smearing the mixed slurry into the grooves again, then inlaying the color clay material, leveling the color clay material, repeating for 3 to 6 times until the grooves are completely leveled by the color clay material; then tearing off partial plastic film, engraving and inlaying further in the above method until all engraving and inlaying work is completed; and (6) burning the green body. By adopting the inlaying process of Nixing pottery, the mutual absorption of the color clay material and the green body can be realized, the color clay material and the green body are unlikely to drop and crack in the burning process, and the burning success rate is high.

Description

technical field [0001] The invention relates to a manufacturing process of Nixing pottery, in particular to an inlay process of Nixing pottery. Background technique [0002] The process of Nixing pottery mainly includes the following steps: 1) Preparation of blank: the blank is selected from the soil east of the Qinjiang River across the urban area of ​​Qinzhou City, commonly known as Dongni (soft clay, yellow-white in color, containing a small amount of quartz sand) , which plays the role of adjusting plasticity and combination in the production process of Nixing pottery), and the soil in the west of Qinjiang River, commonly known as Xini (containing a small amount of K 2 O, NaO, CaO, MgO, Fe 2 0 3 、TiO 2 , MnO 2 , is a kind of purple mudstone with high iron content, the color is purple red, the surface layer has a small amount of iron dissemination, it is hard clay, and the plasticity and bonding are poor), according to 40-60% of Dongni and Xini 40-60% by weight are m...

Problems solved by technology

Since the surface decoration of Nixing pottery products is mainly carved, and because the surface of Nixing pottery will be oxidized with a layer of gray matter during the firing process, it needs to be polished to show the true color of its kiln transformation, but the colorful colors produced by the kiln transformation will also be in harmony with The decorative patterns carved on the surface are integrated, making the decorative patterns not obvious and difficult to achieve a good decorative effect

Although in recent years, white clay and yellow clay are inlaid on the carved patterns and then fired to achieve the contrast of decorative patterns, due to the shrinkage (expansion coefficient) of the white clay, yellow clay and Nixing pottery embedded on the surface of the body, ) is different, it is easy to fall off or crack during the firing process, and the yield is only about 20%, which seriously affects the decorative effect
