High temperature transmutation star glazed ceramic glaze and preparation technology of high temperature transmutation star glazed ceramic

Abstract

The invention relates to the field of ceramic products and manufacturing processes, in particular to a high temperature transmutation star glazed ceramic glaze and a preparation technology of high temperature transmutation star glazed ceramic. The invention is characterized in that the glaze comprises the following ingredients (by weight): 35-40 parts of feldspar, 5-8 parts of kaolin, 2-5 parts oflimestone, 10-15 parts of talc, 15-20 parts of quartz, 5-8 parts of bone ash and 5-8 parts of industrial iron red powder. The high temperature transmutation star glazed ceramic produced by using thehigh temperature transmutation star glazed ceramic glaze is different from traditional transmutation glaze as follows: the black base is completely covered with golden color, etc. on the surface suchthat the ceramic is archaized but not ancient, is creative on the basis of forefathers, is gold-like and silver-like, is a very magic and varied porcelain, and has unique artistic beauty and spiritualfeeling; the glaze has high viscosity at high temperature, and is easy to form bubbles during firing, which helps enrich iron and precipitate crystals; and spots are evenly spread on the glaze.

Description

technical field [0001] The invention relates to the field of ceramic products and manufacturing techniques, in particular to a high-temperature kiln-changing Tianxing glaze ceramic glaze material and a high-temperature kiln-changing Tianxing glaze ceramic preparation process. Background technique [0002] Kiln-changing glaze, as the name suggests, is an unexpected glaze color effect in the firing process of utensils. Because the kiln contains a variety of coloring elements, through oxidation or reduction, the porcelain may show unexpected glaze color effects after it comes out of the kiln. Because the appearance of the kiln-changed glaze is accidental, the shape is special, and people do not know its principle. They only know that it is obtained from the change of the roasting process in the kiln, so it is called "kiln-changed glaze". Unpredictable, unique. Black-glazed porcelain is a kind of kiln-changed glaze, also known as Tianmu glazed porcelain, and its decoration is ...

AI Technical Summary

Problems solved by technology

There are some deficiencies in the traditional Tianmu glaze formula and firing process, such as gold or silver dots appearing on the glaze surface, but due to the use of iron-containing minerals as Fe in traditional glazes 2 o 3 The main source of , its content is not easy to control, resulting in the effect of Tianmu glaze is not easy to show, when Fe 2 o 3 When Fe is too small, oil droplets cannot be formed. 2 o 3 When it is too high, iron spot rust will be formed; during the firing process, the heating time is too fast (generally within 1-1.5 hours to the firing temperature), and the holding time is too short (generally 20-40 minutes), resulting in The glaze surface is uneven and the crystals are irregular; the traditional Tianmu glaze has a black base as the main color, with few embellishments and rich colors; the thickness of the glaze layer is uneven, resulting in uneven size of oil droplets; the high temperature viscosity is not enough, it is not easy to form air bubbles, and then affect the crystal.
