Embodiment 1

[0022] Recipe 1:

[0023] Nepheline orthoclase: 55%,

[0024] Talc: 15%,

[0025] CaCO 3 :15%,

[0026] MgCO 3 :7%,

[0027] Kaolin: 7.5%,

[0028] CuCO 3 : 0.5%.

[0029] According to formula 1, weigh the components and mix them fully into the grinding tank, add water equivalent to 60% of the weight of the dry powder and grind for 5 hours. The particle size has been tested through a 350-mesh sieve, and the residue is about 1g to 3g. Then adjust the ground glaze to a true specific gravity of 42-45, spray or soak it on the pottery, dry it, and then go into the kiln for glaze firing at a temperature of 1185°C-1200°C for 9 hours. After cooling out of the kiln, the ancient green glaze is obtained.

[0030] The prepared ancient green glaze has a delicate and soft glaze surface, rich texture and simple and simple color.

Embodiment 2

[0032] Recipe 2:

[0033] Nepheline orthoclase: 60%,

[0034] Talc: 10%,

[0035] CaCO 3 :15%,

[0036] MgCO 3 :7.5%,

[0037] Kaolin: 7%,

[0038] CuCO 3 : 0.5%.

[0039] According to formula 2, weigh each component and mix them fully into the grinding tank, add water equivalent to 50% of the weight of the dry powder and grind for 12 hours. The particle size has been tested through a 350-mesh sieve, and the residue is about 1g to 3g. Then adjust the ground glaze to a true specific gravity of 42-45, spray or soak it on the pottery, dry it and then go into the kiln for glaze firing at a temperature of 1185°C-1200°C for 10 hours. After cooling out of the kiln, the ancient green glaze is obtained.

[0040] The prepared ancient green glaze has a delicate and soft glaze surface, rich texture and simple and simple color.

Embodiment 3

[0042] Recipe 3:

[0043] Nepheline orthoclase: 65%,

[0044] Talc: 15%,

[0045] CaCO 3 :10%,

[0046] MgCO 3 :4%,

[0047] Kaolin: 5%,

[0048] CuCO 3 :1%.

[0049] According to formula 3, weigh the components and mix them fully into the grinding tank, add water equivalent to 60% of the weight of the dry powder and grind for 10 hours. The particle size has been tested through a 350-mesh sieve, and the residue is about 1g to 3g. Then adjust the ground glaze to a true specific gravity of 42-45, spray or soak it on the pottery, dry it and then go into the kiln for glaze firing at a temperature of 1185°C-1200°C for 10 hours. After cooling out of the kiln, the ancient green glaze is obtained.

[0050] The prepared ancient green glaze has a delicate and soft glaze surface, rich texture and simple and simple color.

Abstract

The invention provides ancient green crackled glaze for ceramic decorations and a preparation method of the ancient green crackled glaze. The ancient green crackled glaze comprises the following components: 50-70 percent of nepheline orthoclase, 10-15 percent of talc, 10-15 percent of CaCO3, 3-8 percent of MgCO3, 4-8 percent of kaolin and 0.5-1.0 percent of CuCO3. The preparation method comprises the following steps of: weighing all the components, then sufficiently mixing the components, adding the mixture to a grinder, adding water which accounts for 50-60 percent of the dry powder, grinding for 5-12 hours, testing the granularity, and screening the ground mixture by using a 350-mesh screen, wherein residues are about 1-3g; and then blending the concentration of the ground glaze to true specific gravity at 42-45 DEG C, spraying or soaking the glaze onto a ceramic product, airing, then feeding the ceramic product into a kiln, carrying out glaze firing at 1185-1200 DEG C for 9-10 hours, finally naturally cooling and discharging the finished product from the kiln. The prepared ancient green crackled glaze is fine and soft in glaze surface, rich in texture and ancient in color and luster.
