Abstract

The invention discloses a coloring method for variegated copperware. The coloring method comprises the following steps that the variegated copperware obtained after surface treatment is soaked into acetic acid; and after cleaning, the variegated copperware is placed in coloring liquid, wherein the coloring liquid comprises, by weight, 100 parts of deionized water, 10-20 parts of magnesium nitrate, 5-15 parts of barium chloride, 5-10 parts of sodium selenate and 1-3 parts of potassium molybdate. The coloring method has the advantages that stripes on the variegated copperware are clear, and the color is uniform.

Description

technical field [0001] The invention relates to the field of bornite processing, in particular to a method for coloring bornite utensils.
