Embodiment 1

[0012] Embodiment 1, a kind of gold and jade porcelain, the raw material composition of its blank according to parts by weight: 25 parts of albite, 15 parts of quartz, 45 parts of kaolin, 7 parts of barium carbonate, 2 parts of sodium tripolyphosphate, 3 parts of yttrium oxide The raw materials of the glaze are composed of 70 parts of frit glaze, 7 parts of potassium feldspar and 13 parts of kaolin according to the weight parts.

[0013] Among them, the chemical composition of albite is: 19.47% alumina, 69.28% silica, 0.09% iron oxide, 0.05% titanium oxide, 0.7% calcium oxide, 0.52% magnesium oxide, 0.5% potassium oxide, 8.47% sodium oxide , 0.92% margin. The chemical composition of kaolin is: 35.96% alumina, 47.95% silica, 0.22% iron oxide, 0.01% titanium oxide, 0.45% calcium oxide, 0.57% magnesium oxide, 2.17% potassium oxide, 0.2% sodium oxide, 12.47% quantity. The chemical composition of potassium feldspar is: 10.18% alumina, 80.45% silica, 0.03% iron oxide, 0.03% titani...

Embodiment 2

[0015] Embodiment 2, a kind of gold and jade porcelain, the raw material composition of its blank according to parts by weight: 35 parts of albite, 15 parts of quartz, 60 parts of kaolin, 10 parts of barium carbonate, 2 parts of sodium tripolyphosphate, 2 parts of yttrium oxide The raw materials of the glaze are composed of 80 parts of frit glaze, 5 parts of potassium feldspar and 15 parts of kaolin according to the weight parts.

[0016] A method of making gold and jade porcelain: make the blank into a green body, then apply the glaze on the green body, dry it and send it to a kiln for firing. The firing process is as follows: from room temperature to 790°C, it takes 2 hours Continue to heat up to 1250°C for 2 hours; continue to heat up to 1280°C for 3 hours; continue to heat up to 1380°C for 2 hours.

[0017] The prepared gold and jade porcelain was tested by the Fujian Provincial Daily Ceramics Product Quality Supervision and Inspection Center, and the test report is as fol...

Abstract

The invention provides jade porcelain and a making method thereof. The blank of the jade porcelain is composed of the following raw materials in parts by weight: 10-35 parts of sodaclase, 15-30 parts of quartz, 30-60 parts of kaolin, 5-10 parts of barium carbonate, 1-3 parts of sodium tripolyphosphate and 1-5 parts of yttrium oxide; the glaze of the jade porcelain is composed of the following raw materials in parts by weight: 70-80 parts of fritted glaze, 5-10 parts of potassium feldspar and 10-20 parts of kaolin. According to the jade porcelain provided by the invention, the blank, the glaze and the firing process are improved, so that the water absorption of the jade porcelain is not greater than 0.3, the whiteness is high, the thermal shock resistance is good, the lead release is smaller than 0.1, the cadmium release is smaller than 0.1, the quality requirements of the product are satisfied, and the firing temperature and the raw material cost are reduced as well, therefore, the production cost of the product is lowered.

Description

technical field [0001] The invention relates to a daily-use ceramic and a manufacturing method thereof. Background technique [0002] Daily-use ceramics in the prior art generally have many problems such as appearance, poor quality, rough surface features, low whiteness, high lead and cadmium dissolution, high production costs, and low thermal insulation performance. The main reasons are: the blank and glaze formula are not good, the firing process is backward, the price of raw materials and fuel is soaring, and the yield rate is low. Contents of the invention [0003] The purpose of the present invention is to provide a gold jade porcelain with low lead and cadmium dissolution, high whiteness, good thermal shock resistance, low water absorption and low cost and its manufacturing method in view of the deficiencies in the prior art. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] A kind of gold jade porcelain, ...
