Problems solved by technology

[0004] In order to solve the problems that the glaze color and pattern are difficult to control during the firing process of Jun porcelain, and the glaze layer is easy to burst and crack uneven when Jun porcelain comes out of the kiln, the present invention proposes a composite Tang Jun glaze with black background and white spots and uses it to prepare Jun porcelain. In the process of porcelain, the specific glaze color is fired by fixing the formula of the glaze, and the position of the white spot effect is fixed by the way of secondary glazing. At the same time, specific ingredients are added to the formula of the glaze, so that the glaze layer Open slices evenly but not easy to burst

Embodiment 1

[0033] The process of preparing Jun porcelain with black and white white composite Tang Jun glaze includes the following steps:

[0034] Step 1. Firing the plain tire

[0035] Mix 65 parts of kaolin, 20 parts of soda stone, 8 parts of Mujie clay and 7 parts of quartz sand evenly, and stir with water at a mass ratio of 1:1 to obtain a mixture; grind the mixture into a slurry with a ball mill, and finely grind it for 80 minutes. The fineness reaches 250 mesh; the obtained mud is hand-drawn to make a plain tire, and the plain tire is put into a kiln to dry at 860°C for 10 hours, and then cooled to room temperature with the furnace, and the fired plain tire is obtained. ;

[0036] Step 2. Prepare the black base glaze

[0037] Mix 60 parts of feldspar, 5 parts of quartz stone, 12 parts of calcite, 5 parts of iron ore, 5 parts of black medicine and 0.2 part of iron oxide into the ball mill, add water of equal quality to it, and ball mill it into a material with a fineness of 300 m...

Abstract

The invention discloses a black background-white spot composite Tang jun glaze, and a method used for producing jun porcelain with the black background white spot composite Tang jun glaze. According to the method, a ceramic body raw material is subjected to smashing, moulding, and sintering so as to obtain unglazed porcelain bodies; the unglazed porcelain bodies are immersed into a black background glaze slurry for glazing; after airing of the black background glaze slurry on the surfaces of the unglazed porcelain bodies, the surfaces of the unglazed porcelain bodies are coated with a white spot glaze slurry via spot application; after airing, the obtained unglazed porcelain bodies are delivered into a kiln for sintering so as to obtain the black background-white spot composite Tang jun glaze jun porcelain. According to the black background-white spot composite Tang jun glaze and the method, iron element is added into a black priming glaze at a certain ratio; secondary glazing is adopted; the positions of white sport glaze are immobilized; talc powder and bone meal are added into the black background-white spot composite Tang jun glaze at a certain ratio, so that glaze layer crackles are uniform, and cracking is not easily caused. Overglaze color or underglaze color generally adopted in conventional speckle porcelain production is not adopted in the method, so that economic value of jun porcelain is increased via innovation on glazing color and coating; jun porcelain is a featured product of our country, so that the method is used for reflecting advanced technology of China, and social value of jun porcelain is increased.

Description

technical field [0001] The invention relates to the field of ceramic manufacturing, in particular to a composite Tang Jun glaze with black background and white spots and a process for preparing Jun porcelain using the same. Background technique [0002] Jun porcelain originated in the Eastern Han Dynasty. It is one of the five famous kiln porcelains in the Song Dynasty. Famous for its unique kiln transformation art, it has the reputation of "gold is priceless and Jun porcelain is priceless" and "a family is rich, not as good as a piece of Jun porcelain". It is a unique national treasure porcelain in Huangdao Town, Pingdingshan City, Henan Province. Simple shapes, exquisite craftsmanship, complex glaze matching, the magical kiln transformation of "one color in the kiln, and thousands of colors in the kiln", lakes and mountains, clouds and mist, human beings, animals, flowers, birds, insects and fish, etc. The graphic colors and wonderful charm are endlessly changing. The fir...
