Embodiment 1

[0015] According to the following ratio, the raw materials are mixed and ball-milled and passed through a 250-mesh sieve, and the sieve residue is 0.2%, and glazed on the body after biscuit firing. Before 980°C, use an oxidizing atmosphere, and use a reducing atmosphere above 980°C to raise the temperature to the highest temperature. Heat at 1280°C for 10 minutes, cool to 1120°C and hold for 0.5h, then rapidly cool to 950°C and then slowly cool to room temperature.

[0016] The glaze ratio is:

[0017] Yaoli glaze fruit 28%, purple sandstone 10%, fly ash 10%, white agate 12%, calcined kaolin 19%, dolomite 3%, calcite 4%, feldspar 14%.

[0018] The glaze n(SiO 2 ) / n(Al 2 o 3 ) molar ratio=5.54, n(CaO) / n(MgO) molar ratio=6.18, Fe 2 o 3 Molecular weight = 0.021, the color of the glaze is light blue, and the color of the glaze is lighter.

Embodiment 2

[0020] According to the following raw material ratio, the raw materials are mixed and ball milled and passed through a 250-mesh sieve. The sieve residue is 0.2%. Glaze the green body after biscuit firing. Before 980°C, use an oxidizing atmosphere, and use a reducing atmosphere above 980°C to rise to the highest level. After the temperature point is 1250°C, keep warm for 10 minutes, cool down to 1130°C and keep warm for 0.5h, then rapidly cool to 950°C, and then slowly cool.

[0021] The glaze ratio is:

[0022] Yaoli glaze fruit 20%, purple sandstone 10%, fly ash 7%, white agate 15%, calcined kaolin 14%, dolomite 8%, calcite 6%, feldspar 20%.

[0023] The glaze n(SiO 2 ) / n(Al 2 o 3 ) molar ratio=6.46, n(CaO) / n(MgO) molar ratio=3.35, Fe 2 o 3 The number of moles=0.016, the cyan color of the glaze tone is slightly lighter than that of Example 1, and the blue accentuates.

Embodiment 3

[0025] According to the following raw material ratio, the raw materials are mixed and ball milled and passed through a 250-mesh sieve. The sieve residue is 0.2%. Glaze the green body after biscuit firing. Before 980°C, use an oxidizing atmosphere, and use a reducing atmosphere above 980°C to rise to the highest level. After the temperature point is 1270°C, keep warm for 10 minutes, cool down to 1150°C and keep warm for 0.5h, then rapidly cool to 950°C, and then slowly cool.

[0026] The glaze ratio is:

[0027] Yaoli glaze fruit 35%, purple sandstone 15%, fly ash 12%, white agate 8%, calcined kaolin 12%, dolomite 4%, calcite 2%, feldspar 12%.

[0028] The glaze n(SiO 2 ) / n(Al 2 o 3 ) molar ratio=5.78, n(CaO) / n(MgO) molar ratio=5.32, Fe 2 o 3 The number of moles=0.027, the glaze tone is slightly darker than that of Example 2, and the lightness decreases.

Abstract

The invention discloses a preparation method of green glaze of Ru porcelain. By using Jingdezhen local minerals as main raw materials, the glaze is prepared from the following components in percentage by weight: 20-35% of Yaoli glaze pastes, 9-18% of Jiaoyuanwu purple sands, 7-12% of lime-ash soil, 7-15% of white agate, 10-20% of calcined kaolin, 2-8% of dolomite, 2-6% of calcite and 10-20% of feldspar. Steps of proportioning, ball-milling, sieving, biscuit-glazing and firing are carried out to obtain a product. The product is good in decorative effect and strong in sense of art and has wide application prospects.

Description

technical field [0001] The invention belongs to the field of daily-use ceramics, and in particular relates to a preparation method of Ru porcelain celadon. Background technique [0002] Ru official kiln porcelain in the Song Dynasty is famous for its exquisite selection of glaze materials, fine production, clear glaze color, short firing time, and rare handed down from generation to generation. Guan, Ge, Ding, and Jun), so it has also become the focus of long-term attention of archaeologists and ancient ceramics researchers. In the Southern Song Dynasty, Zhou Hui's "Qingbo Magazine" said in volume five: "When Hui came out of Xinjiang, he saw the setter used in it, and the color was lovely... And it was forbidden to burn in the Ru kiln palace. There was agate powder in it as oil (glaze). It is only for the emperor to choose and retreat, and only then is it possible to sell it, which is especially rare in the near future." It shows the prominent status of Ruguan glaze and the...
