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.
