Problems solved by technology

[0003] In recent years, some scholars have studied the imitation technology of Yaozhou kiln Tianqing glaze, but the glaze color of the imitation is far from the real product of Yaozhou porcelain.
Small workshops use glaze stones as glaze raw materials to produce azure glazes with relatively good color. However, glaze stones are complex in composition and the output is small, so they cannot be used for large-scale production.
Due to the immature firing process of Yaozhou kiln sky blue glaze, people's understanding of it can only stay on ancient porcelain

Embodiment 1

[0014] Step 1: Mix 58% potassium feldspar, 22% quartz, 14% calcite, 5% Suzhou soil, and 1% talc to form a mixture by mass percentage;

[0015] Step 2: adding mass ratio to the mixture prepared in the above step 1 is 3.5% zinc oxide, 1% ferric oxide, 0.8% sodium methylcellulose and 0.3% sodium polyphosphate and mix evenly, Put it in a mortar and grind it to 250 mesh, and prepare the glaze slurry with a specific gravity of 1.80g / cm3;

[0016] Step 3: Apply the glaze slurry evenly on the bisque-fired ceramic body. The thickness of the glaze layer is controlled at 0.8mm. Place the ceramic body in a shuttle kiln for firing. When the firing temperature does not reach 1100°C, the shuttle The shuttle kiln is an oxidizing atmosphere, and the air excess coefficient at this time is greater than 1. When the firing temperature reaches 1100 ° C, carbon monoxide gas is introduced into the shuttle kiln to make the kiln in a reducing atmosphere, and the temperature is raised under the reducing...

Embodiment 2

[0018] Step 1: Mix 63% potassium feldspar, 21% quartz, 12% calcite, 1% Suzhou soil, and 3% talc to form a mixture by mass percentage;

[0019] Step 2: adding mass ratio to the mixture prepared in the above step 1 is 5% zinc oxide, 1.5% ferric oxide, 0.8% sodium methylcellulose and 0.3% sodium polyphosphate and mix evenly, Put it in a mortar and grind it to 250 mesh, and prepare the glaze slurry with a specific gravity of 1.70g / cm3;

[0020] Step 3: Apply the glaze slurry evenly on the bisque-fired ceramic body. The thickness of the glaze layer is controlled at 1.0mm. Place the ceramic body in a shuttle kiln for firing. When the firing temperature does not reach 1100°C, the shuttle The shuttle kiln is an oxidizing atmosphere, and the air excess coefficient at this time is greater than 1. When the firing temperature reaches 1100 ° C, carbon monoxide gas is introduced into the shuttle kiln to make the kiln in a reducing atmosphere, and the temperature is raised under the reducing...

Embodiment 3

[0022] Step 1: Mix 59% potassium feldspar, 18% quartz, 17% calcite, 2% Suzhou soil, and 4% talc to form a mixture by mass percentage;

[0023] Step 2: adding mass ratio to the mixture prepared in the above step 1 is 2% zinc oxide, 2% ferric oxide, 0.8% sodium methylcellulose and 0.3% sodium polyphosphate and mix evenly, Put it in a mortar and grind it to 250 mesh, and prepare the glaze slurry with a specific gravity of 1.75g / cm 3 ;

[0024] Step 3: Apply the glaze slurry evenly on the bisque-fired ceramic body, the thickness of the glaze layer is controlled at 0.7mm, place the ceramic body in a shuttle kiln for firing, and when the firing temperature does not reach 1100°C, the shuttle The shuttle kiln is an oxidizing atmosphere, and the air excess coefficient at this time is greater than 1. When the firing temperature reaches 1100 ° C, carbon monoxide gas is introduced into the shuttle kiln to make the kiln in a reducing atmosphere, and the temperature is raised under the red...

Abstract

The invention relates to an imitation technology method for celeste glaze of Yaozhou porcelain. The imitation technology method comprises the steps: using potash feldspar, quartz, clay, calcite, Suzhou clay and talc as main raw materials and using ferric oxide as a colorant; mixing the raw materials and the colorant with zinc oxide, sodium methylcellulose and sodium polyphosphate to prepare glaze slip; uniformly applying the glaze slip on a ceramic green body after biscuit firing, and firing the ceramic green body with a glazing color close to an ancient celeste glaze. The physical performance, the chemical composition and the microstructure of the celeste glaze fired according to the imitating technological method are all close to those of the ancient celeste glaze, and a good firing effect is achieved; when the imitation technology method is used to fire the celeste glaze of Yaozhou porcelain, the raw materials are basically generalized, the production cost can be lowered, and a mature preparation process is provided to the industrial production of the celeste glaze of Yaozhou porcelain in future; the imitation technology method has the characteristic of cost and energy saving.

Description

technical field [0001] The invention relates to the technical field of preparation of ceramic materials, in particular to a method for imitating the azure glaze of Yaozhou kiln. Background technique [0002] Yaozhou kiln is a famous kiln in Chinese history. Among the two major celadon kilns in the north and south of my country, it is known as the crown of carved celadon and the representative of celadon in northern China. In the Five Dynasties, celadon was mainly fired, and azure and light azure glazes were created, which pioneered the firing of azure porcelain in China. The azure glaze color is produced through the development process of the tone from blue to light. The enamel has good transparency and has cracks. It is the most elegant glaze color among the celadon wares fired in this kiln. [0003] In recent years, some scholars have studied the imitation technology of Yaozhou kiln Tianqing glaze, but the glaze color of the imitation is far from the real product of Yaozh...
