Sagger for preparing artworks in ceramic firing process and preparation process of sagger

Abstract

The invention relates to a sagger for preparing an artwork in a ceramic firing process and a preparation process of the sagger, wherein the sagger can improve the artistic value of the sagger and change the use purpose of the sagger. The inner surface of the sagger is provided with a glaze layer which is the same as ceramic artworks to be fired. Meanwhile, the sagger is prepared from the followingraw materials in parts by weight: 5 to 15 parts of purple kibushi kaolin, 17 to 25 parts of alkaline stone, 25 to 35 parts of clay, 30 to 40 parts of quartz, 0.1 to 1 part of dietary alkali, 5 to 20parts of white feldspar and 5 to 10 parts of aluminum oxide. Characters or patterns are also drawn or carved on the outer surface of the sagger; in the firing process of the ceramic artwork, firing ofthe sagger artwork is added, the compounding ingredients of the sagger are changed, the surface of the fired sagger is smoother, and the representation of artistic forms is facilitated; a glaze blankof the ceramic and a glaze blank of the sagger are coated with a same glaze, the surface glaze color of the fired ceramic is similar to the inner surface glaze color of the sagger, the anti-counterfeiting effect is achieved, the fired sagger can continue to contain the ceramic and can also exist in an independent artwork form, the value of the sagger is improved, the process cost is reduced, andthus the effect of saving resources is achieved.

Description

technical field [0001] The invention belongs to the technical field of ceramic firing, and in particular relates to a sagger and its preparation which can improve its own artistic value and change the purpose of use in the process of firing ceramics in the process of traditional coal or firewood firing ceramic artworks craft. Background technique [0002] Saggers are used as firing kiln tools in the ceramics and refractory industries. Saggers are used to hold green bodies. Stacking saggers of the same type can increase the density of kilns and the utilization rate of kilns. Secondly, avoid ceramics such as Jun porcelain. Artwork glazed products are in direct contact with the flame, and are polluted by soot and soot, which makes the glaze color of the product black and slag on the glaze surface, resulting in defects such as fire spurs (the glaze surface is rough yellowish brown), ash and slag. In the prior art, saggers are made of refractory materials, and are mostly used in...

AI Technical Summary

Problems solved by technology

In the prior art, saggers are made of refractory materials, and are mostly used in downdraft kilns for ceramic artworks such as firewood and coal-fired Jun porcelain. During the firing process, there is no other use value except for filling the blank, until it is discarded, so the function of the sagger is single, and it is a waste of resources
