Embodiment 1

[0065] Experimental preparation: The traditional pottery is drawn with commonly used pottery clay, then fired at a high temperature of 1000°C to make pottery, and naturally cooled in a kiln to obtain a green body. Preparation of raw materials for glaze: sort hard raw materials such as feldspar, quartz, and calcite used locally in Yuzhou-coarse crushing (with jaw crusher)-medium fine crushing (wheel mill) for later use; calcined bovine bone and talc for medium fine crushing spare.

[0066] Basic glaze preparation method: in mass percentage, 65% feldspar, 15% quartz, 15% calcite, 5% calcined talc are mixed, add the nano iron oxide of total mass 0.5% additionally (particle diameter is 30 nanometers, and purity is 99.9 %, provided by Shanghai Shuitian Material Technology Co., Ltd.), mixed evenly to obtain a mixed glaze. The basic glaze raw materials are provided by Dasong Guanyao Porcelain Industry Co., Ltd. (see attached table 1).

[0067] According to the mass ratio of mixed g...

Embodiment 2

[0070] 1. Experimental preparation: with embodiment 1.

[0071] 2. In mass percentage, mix 65% feldspar, 15% quartz, 15% calcite, 5% calcined talc, plus 1.0% nano-iron oxide with a total mass of 1.0%, and mix them evenly.

[0072] 3. According to the mass ratio of mixed glaze: ball: water = 1:1.5:0.7, add ball mill, wet ball mill processing, the glaze fineness is over 180 mesh sieve and the balance is less than 0.06wt%, and the water content of the glaze slurry is controlled at 45% by weight. The calcined green body is glazed by dipping the glaze, and the thickness is controlled at about 1mm. After drying, it is fired in a kiln (same as Example 1), and cooled naturally to obtain azure Jun porcelain ( diagram 2-1 ,2-2).

[0073] 4. Summary: The color of the obtained utensils is azure, and the color is uniform. The results of the spectrophotometer show that the color difference (△E value) is only 0.38, which is very close to the Song Jun official kiln porcelain (04Y98) ( Fi...

Embodiment 3

[0075] 1. Experimental preparation: with embodiment 1.

[0076] 2. Mix 65% feldspar, 15% quartz, 15% calcite, 5% calcined talc, and 1.5% nano-iron oxide with a total mass of 1.5% by mass percentage.

[0077] 3. According to the mass ratio of mixed glaze: ball: water = 1:1.5:0.7, add ball mill, wet ball mill processing, the glaze fineness is over 180 mesh sieve and the balance is less than 0.06wt%, and the water content of the glaze slurry is controlled at 45% by weight. The calcined green body is glazed by dipping the glaze, and the thickness is controlled at about 1mm. After drying, it is fired in a kiln (same as in Example 1), cooled naturally to obtain sky blue Jun porcelain ( Figure 3-1 , 3-2).

[0078] 4. Summary: The color of the obtained utensils is sky blue, and the color is uniform. The results of the spectrophotometer show that the color difference (△E value) is only 0.05, which is very close to the Song Jun official kiln porcelain (74S71) ( Figure 3-3 ), especi...

Abstract

The invention relates to a re-sintering method for firing imitated Song Jun official porcelains based on a nano ferric oxide glaze and series of fired imitated Song Jun official porcelains. According to the method, nano ferric oxide is added to a basic glaze and is directly glazed in a form of a basic ingredient of the glaze and then fired, so that the defects that a conventional re-sintered Song Jun official porcelain process is low in yield, complex in sintering process, too bright in color, too straight in color, opacifying effect is not obvious and the like can be overcome; and the purpose that the re-sintered Song Jun official porcelains have the glaze colors of powdery cyan, celeste, azure, grayish blue and the like of series of Song Jun official porcelains can be achieved by controlling the color of a glaze layer by controlling and adjusting the parameters of the mass ratio of the nano ferric oxide in the basic glaze, the firing temperature and the like. In addition, a nano material has the characteristics of being high in diffusion ability in Jun porcelain glaze firing, and beneficial to uniform distribution of a coloring agent in a Jun porcelain glaze layer, so that a sintered Jun porcelain product is uniform in color, the viscosity of the glaze layer in the glaze firing process can be effectively reduced, the defects of air holes and the like on the surface of the glaze porcelain are avoided, and the firing success rate of the Jun porcelain is increased.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a refiring method for firing imitation Song Jun official porcelain based on nano-iron oxide glaze and a series of fired imitation Song Jun official porcelain. Background technique [0002] According to relevant historical records, Jun porcelain was created and fired in the Tang Dynasty, and reached its peak in the Northern Song Dynasty, ranking among the top five famous porcelains in the Song Dynasty. The glaze color of Jun porcelain is unpredictable. It can be said that it is as blue as the blue sky, as white as jade, as red as begonia, as purple as rose, and as lustrous as agate. In particular, the azure glaze color presented by the official kilns of the Song Dynasty has been widely praised by people for its simple and heavy style. The ancients once used "like jade but not jade is better than jade", "after the rain, the sky is clear and the clouds are broken", etc...
