Double firing manufacturing method of under-glaze decoration ceramic

Abstract

The invention provides a manufacturing method for an under-glaze decoration pottery and porcelain twice fired, which has the steps that: firstly, an unburnt earthenware body fired by high temperature is made; secondly, low temperature over-glaze decoration paint is used to carry out painting decoration on the unburnt earthenware body, and the paint is adhered on the unburnt earthenware body; thirdly, the unburnt earthenware body after decorated by the painting is sent into a low temperature decorating kiln to carry out low temperature baking, and the paint on the unburnt earthenware body and the unburnt earthenware body are combined together; fourthly, transparent glaze is painted on the unburnt earthenware body after baked by the low temperature; fifthly, the unburnt earthenware body after painted by the transparent glaze is sent into a high temperature kiln to be fired by high temperature, and the under-glaze decoration pottery and porcelain is made. The pottery and porcelain manufactured by the method solves the problem that the picture wears after the under-glaze decoration pottery and porcelain is used for a long time. After fired in high temperature, the paint and glaze are tightly blent, the effect similar to rain drop glaze appears in the place where the paint is thick, artistic quality is strong, decoration effect is good, and esthetics is increased.

Description

technical field [0001] The invention provides a ceramic production method. Background technique [0002] At present, in the production of high-grade daily-use porcelain, most of them adopt the technical method of second firing and decal decoration of in-glaze color and over-glaze color. The main production process of in-glaze ceramics is to draw patterns on mud blanks, spray glaze, and then put them into kilns for high-temperature firing. The overglaze color is made by firing white glaze porcelain first, decals are applied on the white glaze, and then baked in a kiln at a temperature of 600°C-900°C. The disadvantage is that the picture will be worn after a long time of use. And this decal decoration picture effect is straight-forward, lacks artistry. [0003] There is also an underglaze color process method, which is to add color and cover glaze on the green body, biscuit body or glaze body, and fire it at a high temperature of about 1340 ℃ once, so that the color material...
