On this basis, in the Yuan Dynasty in Jingdezhen, a type of iron-painted underglaze porcelain similar to blue-and-white porcelain appeared. In "Chemical Composition and Technological Characteristics of Northern Song Dynasty Brown Colored Porcelain Pillows in Hutian Kiln in Jingdezhen", the sample photos shown by the author limit its further development and application to a certain extent

Embodiment 1

[0015] The first step: the weight percent of the brown color color material formula is: ocher 65%, glass powder 25%, and calcite 10%; the chemical composition weight percent of the ocher, glass powder, and calcite is shown in the table above.

[0016] The second step: Weigh and mix the raw materials according to the requirements of the colorant formula, and put them into the ball milling equipment for 20 minutes with the weight ratio of material: ball: water of 1:2:0.8.

[0017] Step 3: In the high-temperature electric furnace, use 1.5 hours to raise the temperature slowly, so that the temperature in the furnace reaches 400°C, and fully remove the moisture contained in the product; then raise the temperature to 1350°C for 5 hours, and keep it for 2 hours, so that the raw materials are fully melted, Effectively synthesize the required color materials; finally cool naturally with the furnace.

[0018] Step 4: After the synthesized paint color is cooled, put it into a ball mill w...

Embodiment 2

[0023] The first step: the percentage by weight of the brown color material formula is: ocher 40%, glass powder 10%, calcite 15%, borax 35%; For industrial purity.

[0024] The second step: Weigh and mix the raw materials according to the requirements of the color material formula, and put them into the ball milling equipment for 40 minutes with the weight ratio of material: ball: water of 1:2:1.0.

[0025] Step 3: In a high-temperature electric furnace, heat up slowly for 3 hours, so that the temperature in the furnace reaches 550°C, and fully remove the moisture contained in the product; then heat up to 1150°C for 3 hours, and keep it warm for 1 hour, so that the raw materials are fully melted , Effectively synthesize the required color material; finally cool down naturally with the furnace.

[0026] Step 4: After the synthesized painted color material is cooled, put it into a ball mill with a weight ratio of material: ball: water of 1:2:1.0 and mill it for 10 hours. %.

Embodiment 3

[0031] The first step: the percentage by weight of the brown color material formula is: ocher 50%, glass powder 15%, calcite 25%, borax 10%; For industrial purity.

[0032] The second step: Weigh and mix the raw materials according to the requirements of the colorant formula, and put them into the ball milling equipment for 30 minutes with the weight ratio of material: ball: water of 1:2:0.9.

[0033] Step 3: In a high-temperature electric furnace, use a slow fire for 2 hours to raise the temperature so that the temperature in the furnace reaches 500°C to fully remove the moisture contained in the product; then raise the temperature to 1200°C for 4 hours and keep it warm for 1.5 hours to fully melt the raw materials. Effectively synthesize the required color materials; finally cool naturally with the furnace.

[0034] Step 4: After the synthesized painted color material is cooled, put it into a ball mill with a weight ratio of material: ball: water of 1:2:0.9 and mill it for ...

Abstract

The invention relates to a preparation method of a brown overglazed color material. The brown overglazed color material is prepared from the raw materials including, by weight percentage, 40-70% of ochre, 10-30% of glass powder, 10-30% of calcite and 0-40% of borax through processes of preparation, ball milling, drying, calcination, crushing, rinsing, drying and screening. By adjusting the composition, the brown overglazed color material can be applied to primary firing during high-temperature overglazed coloring as well as secondary firing of high-temperature fired white overglazed coloring without being affected by firing atmosphere, thereby achieving high color presenting stability and good color depth with primitive simplicity and elegance; colored patterns are rich in primitive simplicity, lines are clear, fine and smooth without scattering, and coloring pigments penetrate deep into glaze to well bond with the glaze, avoid wearing and present excellent artistic performance. Besides, the brown overglazed color material fills in the gap of lack of brown overglazed color materials in traditional coloring materials and further has a broad application prospect.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials (ceramics), and in particular relates to a preparation method of brown color material on glaze. Background technique [0002] Applying brown stippling decoration on ceramics is a kind of painting decoration technique that appeared earlier in ancient ceramics in my country. It appeared as early as before the Eastern Han Dynasty. Among the ceramics unearthed from the Qingzhusi kiln site in Xiangyin County, Hunan Province, there are brown glazed glazes of the Eastern Han Dynasty. The Wuzhou kiln also found a three-legged ampoule of Eastern Han Dynasty green glaze stippling with green and yellow glaze applied to the whole body. By the Western Jin Dynasty, this kind of blue-glazed brown stippling porcelain had gradually developed from the south of the Yangtze River to all southern regions. In Hongzhou Kiln in Fengcheng, Jiangxi, a Western Jin celadon-glazed stippling porcelain with brown ...
