Embodiment 1

[0030] The coloring method of embodiment 1 sepia

[0031] 1. Now spray potassium sulfide or ammonium sulfide solution (20g potassium sulfide or ammonium sulfide: 1L water) with a manual watering can from top to bottom to make a background color on the entire copper surface, and the copper surface will immediately reflect the shade Varying gray or black. The greater the concentration of potassium sulfide or ammonium sulfide solution, the darker the color.

[0032] 2. While flushing with water, wipe off the gray and black on the high place with a wiper made of plastic silk (hereinafter referred to as the manual wiper). The expected stereoscopic hierarchy appears.

[0033] 3. Gradually and evenly heat the copper surface until the moisture on the copper surface is removed, then heat it slightly to 100°C-120°C, and then use a pneumatic spray gun or brush to coat a layer of ferric nitrate solution (the ratio is 13g-18g Ferric nitrate: 1L water), then roasted with a slow fire, the...

Embodiment 2

[0035] The coloring method of embodiment 2 brownish red

[0036] 1. Now spray potassium sulfide or ammonium sulfide solution (13.2g potassium sulfide or ammonium sulfide: 1L water) with a manual watering can on the entire copper surface from top to bottom as a background color, and the copper surface will immediately react Gray or black in varying shades.

[0037] 2. Rub it manually. Rinse off the base color of the copper surface while flushing water, so that the copper surface can be restored to be bright and smooth as much as possible. According to the actual needs of the work, a little dark color can be left on the required part; you can also gently wipe the copper surface to make the wiped part smooth. The color has a deeper layer than other parts.

[0038]3. Heat the copper surface until the slight change of amber color appears on the copper surface, and then use a spray gun to spray the ferric nitrate solution (7g~12g ferric nitrate: 1L water) layer by layer on the ent...

Embodiment 3

[0040] The coloring method of embodiment 3 dark brown uneven color

[0041] 1. Polish the copper surface smooth

[0042] 2. Now spray potassium sulfide or ammonium sulfide solution (10g potassium sulfide or ammonium sulfide: 1L water) with a manual watering can from top to bottom to make a background color on the entire copper surface, and the copper surface will immediately reflect the shade Varying gray or black.

[0043] 3. Rinse the copper surface with cold water and at the same time wipe it by hand to wipe out the structure level of the desired front of the work. Heat the copper surface, after the moisture on the copper surface is completely removed, when the copper surface appears amber, use a pen dipped in ferric nitrate solution (the ratio is 25g ferric nitrate: 10g iron black powder: 1L water) On the copper surface, let it leave strokes. At the same time, when the copper surface reaches the desired temperature, turn down the fire slowly, and use the fire and the pen...

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...
