A kind of emerald glaze craft ceramic product and its manufacturing process

Abstract

The invention provides jadeite glaze process ceramics and a manufacturing process thereof. The process comprises a green body and ground glaze and colored glaze orderly applied on the surface of the green body; the green body is prepared from the following raw materials in part by weight: 30-40 parts of kaolin, 8-12 parts of potassium feldspar, 3-8 parts of wollastonite, 3-8 parts of sandstone, and 1-3 parts of sodium oxide; the ground glaze is prepared from the following raw materials in parts by weight: 10-18 parts of halloysite, 8-15 parts of china clay, 8-12 parts of perlite, 8-12 parts ofbrucite, 5-10 parts of talcum powder, and 3-8 parts of aluminum oxide; the colored glaze is prepared from mica powder, dickite powder and colorant in weight ratio of 1-3: 1-2: 3-5. The jadeite glazeprocess ceramics manufactured from the raw materials and the process provided by the invention is smooth in glaze surface and delicate in gloss, display the magnificent color and luster like natural jadeite; the radioactivity is low, the thermal stability is good, and the glaze surface cracking is avoided in the burning process.

Description

technical field [0001] The invention belongs to the technical field of daily-use craft ceramics, and in particular relates to a jadeite glaze craft ceramic product and a manufacturing process thereof. Background technique [0002] Since the development of ceramic handicrafts, there are too many designs, colors and varieties. As a superior work and with technological value, it is painted ceramics. The painting and coloring of painted ceramics mostly use low-temperature glaze. Due to the limitation of painting and firing technology, its color and The pattern looks dull, and the jadeite glaze formed after kiln transformation in painted ceramics has delicate colors and bright luster, which looks like jadeite inlaid in it, very beautiful. It is difficult to completely copy and fire the ancient jadeite glazed ceramics due to the increasing decline and the gradual loss of the firing process. The firing rate is not high, so it is necessary to provide a new technology suitable for m...

Problems solved by technology

[0002] Since the development of ceramic handicrafts, there are too many designs, colors and varieties. As a superior work and with technological value, it is painted ceramics. The painting and coloring of painted ceramics mostly use low-temperature glaze. Due to the limitation of painting and firing technology, its color and The pattern looks dull, and the jadeite glaze formed after kiln transformation in painted ceramics has delicate colors and bright luster, which looks like jadeite inlaid in it, very beautiful. It is difficult to completely copy and fire the ancient jadeite glazed ceramics due to the increasing decline and the gradual loss of the firing process. The firing rate is not high, so it is necessary to provide a new technology suitable for modern methods of firing, and the jadeite glaze craft ceramic products used for viewing and playing are often in contact with people, so they need to have the characteristics of low radiation, especially It is a jadeite glaze craft ceramic product with low radiation and good thermal stability, which has very high collection value and market value
