| titleOfInvention | Method for producing brochantite patina on copper |
| abstract | A passthrough method is provided in which the surface of an industrial grade, low-grease precursor made of copper, with a defined surface roughness, is patinated. For this purpose the precursor material, connected as the anode, is passed through an electrolysis bath, containing sodium carbonate and/or sodium hydrogencarbonate as well as sodium sulfite and/or sodium disulfite, with a temperature of 30° C. to 90° C. and a current density of 1 A/dm 2 to 20 A/dm 2 as bath parameters, for a residence time of 10 seconds to 12 minutes. The precursor material is rinsed and then moved through a fixing bath at a temperature of 35° C. to 95° C. for a residence time of 10 seconds to 120 seconds, and lastly, after a further rinsing, is dried. The fixing bath contains at least one of the oxidation agents: hydrogen peroxide (H 2 O 2 ), potassium chlorate (KClO 3 ), potassium peroxodisulfate (K 2 S 2 O 8 ), potassium permanganate (KMnO 4 ), of copper sulfate (CuSO 4 .5H 2 O). |
