Technological process for decoration and repair of paint with five colors under glaze

Abstract

The invention relates to a technological process for decoration and repair of paint with five colors under glaze. The technological method comprises the steps of: preparation of pigments, decorative drawing, decorative picture repair as well as glazing and firing, namely, according to the step of preparing the frankincense oil pigments, mixing and blending inorganic pigments and frankincense oil according to a weight proportion of 4: 1, grinding for 2 hours, and diluting the prepared frankincense oil pigment by using camphor oil; then carrying out decorative drawing and picture repair; and conveying drawn and repaired porcelain to a shuttle kiln at 200 DEG C to be dried, taking the porcelain out after being dried, applying high-temperature glaze onto the porcelain, then conveying the porcelain into the shuttle kiln again, firing the porcelain to 1000 DEG C by using oxidizing flame, then firing the porcelain by using reducing flame, and naturally cooling to the finished product, wherein the firing temperature under the reducing flame is 138 DEG C, and the whole firing process is 6 hours. The technological process is breakthrough and technological supplement of the five-color painted traditional process under glaze; the limitation of the five-color painted traditional process under glaze is remedied; the technological expression technique is promoted; and craft ceramics with five colors under glaze with a brand-new artistic effect can be achieved by reducing the defective percentage.

Description

technical field [0001] The invention relates to a process method for decoration and repair of underglaze multicolored oil paint, which is a technique for decorating and drawing high temperature underglaze multicolored porcelain and repairing underglaze multicolored porcelain with unsatisfactory color and artistic effect method. Background technique [0002] At present, the underglaze five-color craftsmanship in the ceramic industry basically follows the traditional double-hook Fenshui technique and the underglaze biscuit drawing process, which is to draw patterns on the ceramic body and then glaze and fire. The existing underglaze five-color traditional craft There are limitations, that is, the representation technique is single, and it is impossible to make breakthroughs and innovations in artistic effects; there are also defects that cannot be repaired after the porcelain is fired, and can only be treated as defective products or sold at low prices.
