Embodiment 1

[0023] A Junru powder green glaze, which is prepared from the following raw materials in parts by weight: 45-55 feldspar, 13-17 quartz, 13-17 calcite, 1.4-1.6 iron ore, 0.8-1.2 bone ash, silicic acid Zirconium 3-5, tin oxide 1.5-2.5, talc 2.5-3.5, white feldspar 8-12.

[0024] In the formula, yellow feldspar and white feldspar are used as feldspar raw materials, and their metal content is different. They are mainly used as solvents, and the metal ions contained in them can also help color; The main raw material is mainly used for dissolution aid. Talc mainly provides magnesium ions, which can improve the glaze. The iron oxide content in iron ore is more than 70%, which is used to provide iron element for color development. In this formula, bone ash and zirconium silicate can significantly enhance the opacity effect of glaze. Tin oxide, as a chemical additive, contributes to the improvement of the color and the stability of the glaze quality. In the present invention, except...

Embodiment 2

[0034] A Junru powder green glaze, which is prepared from the following raw materials in parts by weight: 50 feldspar, 15 quartz, 15 calcite, 1.5 iron ore, 1 bone ash, 4 zirconium silicate, 2 tin oxide, 3 talc, albino 10.

[0035] The specific preparation method is as follows:

[0036] (1) Mix the above raw materials, ball mill, and pass through 250 sieves to obtain glaze slurry;

[0037] (2) Apply glaze on the biscuit fired carcass by dipping glaze, spraying glaze and other methods; the thickness of glaze is 0.7-1.0mm;

[0038] (3) Firing in an electric mixed firing kiln (such as the product provided by patent CN201510695873.3), which is specifically divided into the following stages:

[0039] ① Oxidation stage: adopt the electric firing method to raise the temperature from room temperature to 1000 ℃ at a constant speed within 6 hours;

[0040] ②Heavy reduction stage: adopt electric and gas mixed combustion method (on the basis of electric heating, liquefied petroleum gas ...

Embodiment 3

[0045] A Junru powder green glaze, which is prepared from the following raw materials in parts by weight: 54 feldspar, 17 quartz, 14 calcite, 1.4 iron ore, 0.9 bone ash, 4.5 zirconium silicate, 1.5 tin oxide, 2.5 talc, White feldspar9.

[0046] The specific preparation method is as follows:

[0047] (1) Mix the above raw materials, ball mill, and pass through 250 sieves to obtain glaze slurry;

[0048] (2) Apply glaze on the biscuit fired carcass by dipping glaze, spraying glaze and other methods; the thickness of glaze is 0.7-1.0mm;

[0049] (3) Firing in an electric mixed firing kiln (such as the product provided by patent CN201510695873.3), which is specifically divided into the following stages:

[0050] ① Oxidation stage: use electric firing method to rise from room temperature to 1000 ℃ at a constant speed in 6.5 hours;

[0051] ②Heavy reduction stage: adopt electric and gas mixed combustion method (on the basis of electric heating, liquefied petroleum gas is introduced...

Abstract

The invention discloses Jun and Ru light greenish-blue glaze. The Jun and Ru light greenish-blue glaze is prepared from raw materials including, by weight, 45-55 parts of melilite, 13-17 parts of quartz, 13-17 parts of calcite, 1.4-1.6 parts of iron ore, 0.8-1.2 parts of bone ash, 3-5 parts of zirconium silicate, 1.5-2.5 parts of tin oxide, 2.5-3.5 parts of talc and 8-12 parts of feldspar. The Junand Ru light greenish-blue glaze has the advantages that formulas and firing processes are optimized, accordingly the fired Jun and Ru light greenish-blue glaze is light greenish-blue and elegant, isbright and smooth just like jade, is free of cracking, is excellent in milky property just like Jun porcelain, and further has the characteristics similar to pure glaze surfaces and exquisite and soft glaze quality of Ru porcelain; the Jun and Ru light greenish-blue glaze is high in yield and suitable to be used for popularizing and applying practical porcelain, and the optimal yield of the Jun and Ru light greenish-blue glaze can reach 90% at least.

Description

technical field [0001] The invention belongs to the technical field of Jun porcelain production, and in particular relates to a Junru powder green glaze. Background technique [0002] The five famous kilns in China are: Jun Kiln, Ru Kiln, Guan Kiln, Ding Kiln and Ge Kiln. [0003] Among them, the Jun kiln is a unique national treasure porcelain in Shenhou Town, Yuzhou City, Henan Province. The opalescent state of the Jun glaze and the phenomenon of kiln transformation are the two appearance characteristics that constitute the artistic beauty of Jun porcelain. The opalescence state refers to the beautiful azure semi-opacity state of Jun kiln glaze like green agate or opal, which not only makes Jun glaze produce a series of blue from light to dark, but also endows it with a subtle luster and elegant Texture, reducing the coquettish floating light caused by glaze vitrification. The phenomenon of kiln change means that Jun glaze melts and flows at high temperature, and the opa...
