Embodiment 1

[0018] Example 1 The preparation method of a jade Ru porcelain bowl (caliber 15cm, height 7cm, foot diameter 6.5cm):

[0019] (1) Green body preparation: check, select and rinse kaolin raw materials (including SiO 2 72%, Al 2 o 3 21%, CaO 0.4%, MgO 0.3%, K 2 O 5%, Na 2 O 0.5%, MnO 0.04%, and Fe 2 o 3 Content2 content <0.3%, the same below), after being crushed, it will be ground in a ball mill, and after iron removal, it will be filtered, smelted, stale, and hand-drawn to form a green body;

[0020] (2) Preparation of plain tire: put the green body into the kiln and burn it for 3 hours at 800°C to 900°C (it takes 40 minutes before 500°C, and then the temperature can be raised evenly), after cooling, it leaves the kiln to obtain the plain tire;

[0021] (3) Glaze preparation: take aphanitic quartz and calcinate it at 1250-1300°C for 7 hours, and then crush it into particles suitable for ball milling for later use; take bone ash and roast it at 850-950°C for 2 hours, and...

Embodiment 2

[0023] Example 2 The preparation method of a jade Ru porcelain water cup (diameter 8cm, height 10cm) is basically the same as Example 1, the difference is:

[0024] ①Glaze preparation: take aphanitic quartz and calcinate at 1250-1300°C for 6 hours, then crush it into particles suitable for ball milling for later use, and take bone ash at 850-950°C for 2.5 hours, then crush it into granules suitable for ball milling for later use , and take feldspar, calcite and soda stone respectively, and then crush them according to the glaze ratio (60% feldspar, 20% calcite, 12% aphanitic quartz, 4% soda stone, 2% ashes, and 2% plant ash). The ingredients are mixed and then put into a ball mill for grinding, after passing through a 250-mesh sieve, iron is removed, and glaze is applied on the above-mentioned plain tire;

[0025] ② Firing: Put the plain body into the kiln after glazing, oxidize and evaporate at 300°C-600°C for 1.5 hours (during which the temperature rises at a constant speed)...

Embodiment 3

[0027] Example 3 The preparation method of a jade Ru porcelain vase (bottom foot diameter 12.5cm, height 36cm) is basically the same as Example 1, except that:

[0028] ①Glaze preparation: take cryptocrystalline quartz and calcinate at 1250-1300°C for 8 hours, then crush it into particles suitable for ball milling for later use, and take bone ash at 850-950°C for 2.5 hours, then crush it into granules suitable for ball milling for later use , and take feldspar, calcite, soda stone to break, and then according to the glaze ratio (feldspar 72%, calcite 10%, aphanitic quartz 7%, soda stone 3%, bone ash 4%, plant ash 4%) The ingredients are mixed and ground into a ball mill, and iron is removed after passing through a 180-mesh sieve, and glaze is applied on the above-mentioned plain tire;

[0029] ② Firing: Put the plain body into the kiln after glazing, oxidize and evaporate at 300°C-600°C for 2.5 hours (the temperature rises at a constant speed during the period), and then oxidi...

Abstract

The invention relates to a jade-like Ru porcelain and a preparation method thereof. The jade-like Ru porcelain comprises a body and a glaze, wherein the preparation raw material of the body is of kaolin, and the preparation raw materials of the glaze comprises the following components in percentage by weight: 55%-80% of feldspar, 10%-25% of calcite, 5%-15% of cryptocrystalline quartz, 2%-10% of alkaline stone, 1%-8% of bone ash and 1%-8% of plant ash. According to the jade-like Ru porcelain disclosed by the invention, the Ru porcelain glaze with jade quality is combined with the body with thejade quality, a traditional Ru porcelain firing process is adopted for enabling the porcelain body to show the jade-like translucent state, color and luster are elegant, pale and graceful, a brand new visual impact and an artistic effect can be further generated, and the millenary Ru porcelain can further realize the historic breakthrough. A new species is added in the family of the Ru porcelain,the cultural connotation of the Ru porcelain is enriched, and the added value and the market share of Ru porcelain products are further improved.
