The firing of the iron red gold ring glaze is extremely complicated, and it is closely related to the blank formula, glaze formula and preparation process
The existing iron-based kiln-changed glaze is fired into porcelain. The glaze surface is either small or connected into a large piece of safflower. The size of the safflower is uncontrollable, the shape is single, the saturation of red and black is small, and the artistic value is not high. Low yield

Abstract
The invention relates to the field of glaze and ceramic preparation processes. The iron oxide red gold ring glaze is characterized in that a raw material formula of the glaze comprises the following components in parts by weight: 42-46 parts of feldspar, 8-10 parts of kaolin, 6-7 parts of limestone, 5-8 parts of talcum powder, 12-14 parts of quartz, 10-14 parts of bone ash, 13-17 parts of industrial iron oxide red powder and 7-9 parts of glaze loess. The iron red gold ring glaze and the preparation process of the iron red gold ring glaze ceramic provided by the invention have the following beneficial effects: the fired glaze surface has three characteristics of black base, safflower and gold ring; the glaze safflower is large and controllable in size; the color saturation of the black matrix and the safflower is high; the carthamus tinctorius outer gold ring is clear and visible in thickness.
Description
technical field [0001] The invention relates to the field of preparation technology of glazes and ceramics, in particular to a preparation technology of iron red gold circle glaze and iron red gold circle glaze ceramics. Background technique [0002] The iron-based kiln variable glaze is as famous as Jianzhan, oil drop and other precious glazes. It was once lost. With the unremitting efforts of ceramic people, it was restored in the 1970s. At that time, it caused a sensation in the entire ceramic industry. There are very few people using the golden ring glaze, mainly because it is extremely difficult to fire, so there are few people who try it. The firing of the iron red gold ring glaze is extremely complicated, and it is closely related to the blank formula, glaze formula and preparation process. The existing iron-based kiln-changed glaze is fired into porcelain. The glaze surface is either small or connected into a large piece of safflower. The size of the safflower is un...
