Embodiment 1

[0021] The preparation method of sapphire yellow glaze ceramics for daily use comprises the following steps:

[0022] (1) Prepare sapphire yellow glaze, according to the following proportions by weight: 62 parts of white clay, 13.8 parts of clay bone, 3.6 parts of Suzhou soil, 12.5 parts of glass powder, 3.6 parts of manganese silicate, 4.5 parts of straw ash; : Ball: water = 1: 1.3: 1.3, the ball milling time is 48 hours, after ball milling, pass through a 250-mesh sieve to get sapphire yellow glaze;

[0023] (2) Apply sapphire yellow glaze to the bisque-fired ceramic body by dipping glaze, and then glaze and fire after drying;

[0024] (3) Glazing is fired with roller kiln oxidizing flame, and the firing cycle is 4.5~5 hours. Rise to 1180°C at a uniform speed within 1.5 hours, then drop to 1000°C within 20-30 minutes, quickly drop to 800°C within 20 minutes, then slowly drop to 600°C within 0.5-1 hour, and finally cool down to room temperature naturally. After firing out o...

Abstract

The invention belongs to the technical filed of ceramic glaze, and specifically relates to a preparation method of a sapphire yellow glazed daily use ceramic. The sapphire yellow glazed daily use ceramic comprises 60 to 65 parts of white clay, 12 to 18 parts of an ore named Tugu, 3 to 5 parts of an ingredient named Suzhoutu, 8 to 12 parts of glass powder, 4 to 8 parts of manganous silicate, and 3 to 5 parts of straw ash. According to the preparation method, a series of special chemical reactions of manganous silicate with the Yixing local raw material Tugu at certain temperature are carried out, the special material straw ash is introduced, and an auxiliary reaction is carried out, so that a glaze sagging layer of the sapphire yellow glazed daily use ceramic is green touched with yellow and semitransparent, texture of a green body can be observed dimly through a glaze layer, a novel ceramic expression form with unique style is obtained, high temperature resistance of the glaze sagging layer is excellent, a wide temperature range is provided for later surface flower paper decoration of the sapphire yellow glazed daily use ceramic, and advantages are excellent.

Description

technical field [0001] The invention relates to the technical field of ceramic glazes, in particular to a preparation method of sapphire yellow glaze daily-use ceramics. Background technique [0002] Traditional glazes for ceramic products are monotonous in color and cannot produce special sapphire yellow glazes. With the further changes in social development and the increasing demand for taste and cultural connotation of daily necessities ceramics, it is urgent to develop a sapphire yellow glaze. , to enrich the color types of ceramic products. Contents of the invention [0003] In order to solve the above problems, the present invention provides a preparation method of sapphire yellow glaze ceramics by adopting a reasonable glaze formula and firing process in order to obtain the appearance effect of sapphire yellow glaze on the surface of the glaze layer. [0004] The preparation method of sapphire yellow glaze ceramics for daily use comprises the following steps: [0...
