Abstract

The invention belongs to the technical field of preparation of jun porcelain glaze, and particularly relates to copper-based golden red glaze and a preparation method thereof.The copper-based golden red glaze is prepared from, by weight, 48%-50% of melilite, 16%-20% of white feldspar, 16%-18% of calcite, 8%-10% of quartz, 2%-4% of copper ore, 2%-4% of ZnO, 0.5%-1.5% of SnO2 and 0.4%-0.6% of CuO; the preparation method of the copper-based golden red glaze comprises the following steps: (1) burdening: weighing various raw materials according to the proportion; (2) preparing glaze slip: adding various raw materials into a ball mill, and adding water for ball milling to obtain the glaze slip; (3) glazing: uniformly stirring the glaze slip, and putting a green body which is subjected to biscuit firing and has a clean surface into the glaze slip for glaze dipping; and (4) firing: firing the glazed green body in a kiln. The prepared copper-based golden red glaze is full in glaze color, good in glossiness, high in artistic ornamental value, high in glaze surface hardness, free of cracks, high in yield, low in raw material price and simple in preparation process, large-scale production can be achieved, and the commercial value of the copper-based golden red glaze is improved.

Description

technical field [0001] The invention belongs to the technical field of preparation of Jun porcelain glaze, and in particular relates to a copper-based golden red glaze and a preparation method thereof. Background technique [0002] Golden red glaze is what we commonly call carmine red glaze. It is a low-temperature red glaze made by applying gold-containing red glaze on the fired thin-bodied white porcelain. It uses gold as a colorant and is baked in a furnace at low temperature. , because this kind of red color is like rouge, with a slightly pink tone, it is customary to call it carmine. Gold is used as the coloring agent in the preparation of gold-red glaze by the traditional method. Due to the high price of raw material gold, this increases the production cost of gold-red glaze, which limits its commercial value to a certain extent, and the preparation process is not easy to control. , the yield is low, thereby reducing its artistic appreciation; therefore, in order to o...
