Abstract

The invention discloses a firing technique of blue and white porcelain, which comprises the following steps: 1) a blank is composed of Nixing argil, potash feldspar, quartz, calcined talcum and zirconium silicate; a glaze is composed of lead-free cadmium fusion cake, potash feldspar, calcined talcum, wollastonite and Nixing argil; and a blue material is composed of 10-20 parts of blank, glaze and a cobalt blue material; and 2) making the blank into a billet, trimming, drawing patterns or writing characters on the billet surface by sing the blue material, carrying out glazing treatment, airing, firing in a kiln at 1060-1160 DEG C for 10-15 hours, cooling, and discharging to obtain the finished product. The technique has the advantage of lower firing temperature. The finished blue and white porcelain product has the advantages of high glaze whiteness, bright blue-and-white coloration and clear lines without blooming, and is very delicate.

Description

technical field [0001] The invention relates to a manufacturing process of ceramics, in particular to a firing process of blue and white porcelain. Background technique [0002] Blue and white porcelain, also known as white ground blue and white porcelain, often referred to as blue and white porcelain, is one of the mainstream varieties of Chinese porcelain and belongs to underglaze colored porcelain. Blue-and-white porcelain is made of cobalt ore containing cobalt oxide as raw material. The blue-and-white porcelain body is painted with decorations, and then covered with a layer of transparent glaze. After high-temperature physical and chemical changes, the blue and white are consolidated between the glazes, which are not afraid of acid and alkali corrosion, are not easy to wear, never fade, and never peel off. Traditional blue and white pigments used to paint blue and white porcelain bodies need to be fired at high temperature for 18 to 24 hours before they can appear blue...
