Hot tinting method on copper surface

Abstract

The invention relates to a hot tinting approach on the surface of bronze. By applying different chemistry raw material formulas and according to thinking of designers, the approach applies various chemistry materials to generate the chemical change on the heated copper surface with different copper content at the different temperature; the needy colors showed by the copper surface are controlled depending on the heating time and form various patterns. The clear color blocking material is used to block the colored copper surface. The color and the pattern are bleeded from the inside of the metal, thus, being sparkling and crystal-clear, jade-like, rich and natural in color and strong in teansparency. Therefore, the expressive force, attractiveness and collection value of the copper works or copper sculpture are greatly improved.

Description

technical field

[0001] The invention relates to a modern copper surface thermal coloring technology, in particular to thermally coloring the surface of a copper sculpture to make it present rich and bright colors. Background technique

[0002] Most of the traditional or ancient bronze coloring methods use cold coloring or natural coloring. The method is to put the copper piece outdoors or bury it in the soil, and add some formula to make it slowly change color on the surface. As disclosed in Chinese Invention Patent Application No. 200510038256.2, a water-soluble paint, water-based color paste, pigment and filler are mixed with water to color the bronze ware, so that it presents the color and luster of the ancient bronze ware. The copper parts processed in this way have simple color types, the size and range of color expression cannot be as desired, and the color surface is rough and extremely unstable. At present, people generally use cold coloring for the surface treatme...
