Multicolor penetrating coloring process of colorful copper

Abstract

The invention discloses a multicolor penetrating coloring process of colorful copper. The multicolor penetrating coloring process comprises the following steps of: heating a copper surface, removing steam, and then continuously heating the copper surface; spraying ferric nitrate uniformly on the copper surface by fire and a spray gun alternatively to achieve an expected effect; continuously heating parts designed to be green on the copper surface, repeating heating for a plurality of times until the required temperature is achieved on the parts designed to be green, and coating the parts to be green with a copper nitrate solution by a writing brush; and when the parts are green as required, spraying 2-3 layers of ferric nitrate solution on the entire surface after the temperature of copper is slightly reduced. At the moment, the copper surface takes on the color of brown with green which is blended with yellow and black. The coloring process provided by the invention can overcome the defects of the prior art, is convenient, has a good coloring effect and is capable of keeping the colors bright for a long time, and thus the colors of an entire sculpture are transparent, harmonic and rich.
