Abstract

A method for producing a colour-in-glaze ceramic features use of speical glaze formula, two-pass decoration and two-pass burning, and includes such steps as making patterned paper with high-temp. ceramic pigment, sticking it on white ceramic blank, high-temp. burning, decorating and baking. The advantages of finished ceramic products are high penetrating effect of pigment into glaze, bright and smooth glaze surface, never decolouring, no lead content, and high quality and artistic effect.

Description

Color ceramic and preparation method thereof in the high temperature jilan glaze

The invention provides color ceramic and preparation method thereof in a kind of high temperature jilan glaze, belong to ceramic-like.

The surface decoration of pottery is an important step of beautifying ceramic, and it directly has influence on the value and the artistic effect of ceramic product.The in-glaze decoration ceramic decoration is to grow up on the basis of under glazed, its general employing pyroceramic pigment decoration adds coloured silk and forms through a decoration firing of 1060-1250 ℃ of high temperature on the white biscuit that becomes porcelain, the glaze of goods softens fusion, the particle of new pigment is penetrated in the glaze, cooling back glaze face closure, pattern just immerses moist, and is fine and smooth sparkling and crystal-clear soft, makes goods have anti-mechanical wear and erosion resistance.In-glaze decoration has also thoroughly solved " lead poisoning " problem of porcelain, and the in-glaze decoration pottery of decorating the back once-firing can not satisfy the requirement of high-grade outlet porcelain again because of shortcomings such as overglaze planeness and color light brightness.Chinese patent by retrieval has one piece and is entitled as " ceramic glaze prize single firing process ", CN1070629A, and the 9-14 volume, different with the present invention.Known to the contriver, still there is not the in-glaze decoration of employing double-firing process at present both at home and abroad, there is not the glaze formula that is exclusively used in color ceramic in the jilan glaze provided by the invention yet.

The purpose of this invention is to provide color ceramic and preparation method thereof in a kind of high temperature jilan glaze, this pottery adopts specific glaze formula, decorate back twice firing acquisition and do not change other technology of existing production, equipment, the raw material of glaze is drawn materials greatly and to be produced more than this area or near-earth, and product has light, smooth, will never change colour and higher-grade, high-quality characteristics.

Concrete technical scheme of the present invention is; Color ceramic in a kind of high temperature jilan glaze is characterized in that: the used glaze formula of this pottery is pressed raw material weight than calculating, by feldspar 32-52%, and quartzy 6-24%, talcum 0-6%, rhombspar 2-10%, clay 30-44%; The chemical ingredients of this glaze is: SiO ₂68-74%, Al ₂O ₃11-15%, Fe ₂O ₃0.1-0.3%, CaO1-2.5%, MgO1.8-2.6%, K ₂O3.8-5.2%, Na ₂O2.8-4%, loss on ignition 1.2-2.8%, its medium clay soil can be: the two total amount of Jiangxi china clay 8-14% and Fujian china clay 20-30% is formed, and other raw material is a household china raw material commonly used, and the place of production is not limit.The making method of color ceramic in a kind of high temperature jilan glaze, it comprises existing production technique of household china and made porcelain base, it is characterized in that:＜1〉will execute the glaze of color ceramic in the high temperature jilan glaze inside and outside the porcelain base, go into kiln high temperature and burn till white biscuit;＜2〉be prefabricated into the porcelain marble paper with the blue ceramic pigment color of high temperature cease raining or snowing;＜3〉marble paper is attached on the white biscuit, goes into kiln high temperature and burn till, firing temperature is 1230 °--1320C;＜4〉again row edge, paint in gold and after other decorates, go into the decoration firing kiln decoration firing and form.Wherein＜1〉and＜4 be existing production temperature.

Method of the present invention is compared with existing in-glaze decoration production technique, and secondary is decorated and twice firing though experienced, and many road high temperature firing process do not change existing production technology substantially; Owing to adopt the applique mode, be again on the ceramic whiteware that the glaze that can cooperate is with it done, can make the marble paper paint be penetrated in the glaze admirably, thereby make goods not have lead poisoning, the glaze light, smooth, no concave-convex is not flat-shaped, bright and lustrous exquisiteness, color is will never change colour to fade, and design on the marble paper and collocation of colour also can be flexible and changeable, the quality product height, of high grade splendid with artistic effect, the raw material of glaze is drawn materials easily.

Technology contents of the present invention, under application side tissue, contriver's repeated tests, obtain a most preferred embodiment and be: glaze formulation is a feldspar 42%, and is quartzy 9%, talcum 5%, rhombspar 4%, Jiangxi Boyang china clay 12%, Fujian china clay 28%; The chemical ingredients of this glaze is: SiO ₂70.06%, Al ₂O ₃14.23%, Fe ₂O ₃0.3%, CaO1.49%, MgO2.43%, K ₂O4.09%, Na ₂O3.64%, loss on ignition 2.51% amounts to 98.75%.Adopt household china now to produce base substrate, body recipe is generally: porcelain stone 60-66%, kaolin 40-34%; Chemical ingredients is: SiO ₂64-70%, Al ₂O ₃20-24%, Fe ₂O ₃0.7-1.2%, CaO0.3-0.6%, MgO0.6-0.9%, K ₂O1.4-1.7%, Na ₂O0.7-0.9%, loss on ignition 4-7%.Adopt method of the present invention, wherein the 1st firing temperature and decoration firing kiln color roasting temperature are existing production temperature, and the 2nd high temperature firing temperature (after referring to applique) is 1280 °-1320 ℃, 40 ℃ of the temperature difference.Color ceramic in the high temperature jilan glaze that above-mentioned prescription and technology make has excellent effect, is the high-grade porcelain of ideal.
