Abstract

The invention relates to brown-field milky-white blue-spot glaze. The brown-field milky-white blue-spot glaze is prepared from ground glaze and spot glaze, wherein the ground glaze is prepared from the following components by weight percent: 50 to 60 percent of clay, 30 to 35 percent of feldspar and 10 to 15 percent of quartz; and the spot glaze is prepared from the following components by weight percent: 30 to 35 percent of quartz, 28 to 35 percent of melilite, 15 to 25 percent of calcite, 3 to 6 percent of fluorite, 2 to 4 percent of wood ash, 1 to 3 percent of bone meal, and 5 to 7 percent of zinc oxide. The invention also discloses colored glaze porcelain prepared by utilizing the brown-field milky-white blue-spot glaze. The brown-field milky-white blue-spot glaze disclosed by the invention is novel ceramic split-phase milky-light color glaze, a glaze layer is thick, colors produced by the glaze after being discharged from a kiln has specific variation unpredictable for people, gives people a force and dynamic impression and gives people firm and positive stimulation. The artistic charming is applicable to the beauty of the nature, no artificial pretension is made, and magnificence and solemnity are displayed in the thickness and moisture. The artistic effect of a device is effectively improved. The brown-field milky-white blue-spot glaze has high appreciation and collection value.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a brown-ground milky-white blue-spotted glaze and a process for preparing flower-glazed porcelain using the same. Background technique [0002] Lushan flower porcelain is named after the deep ground, milky white and blue spot three-color flower glaze porcelain produced in Lushan (now under Pingdingshan City, Henan Province) in the Tang Dynasty. In the Tang Dynasty, there were many kilns producing pottery and porcelain throughout the country, but the more famous kilns for producing porcelain mainly produced celadon and white porcelain. "South Green and North White" became the mainstream product of the Tang Dynasty porcelain industry. The three-color glazed porcelain with deep ground, milky white and blue spots produced in Lushan, Henan Province changed the situation that there were only blue and white single-color glazed porcelain at that time, and a new multi-colored glazed por...
