Green Patina on Copper.

paint. Muriatic and other acids are used as I have read. www.modernmasters.com has a system but its very expensive and I want to do large items, although it seems to be relatively safe on lungs. Muriatic fumes, runs, spots and ruins my sprayers. I was thinking of a thick acid base toilet cleaner that will stick. [right now im hacking from Muriatic fumes] . I am trying now to get a green patina on copper paint I have sprayed. Any ideas that work and are easy and safe. |

"I was just looking for copper patina recipe and was to DIY site and found the complete recipe (with amounts) on David Marks workshop. Copper Patina Mixture Following is the list of ingredients and procedures for the copper-patina solution provided by David Marks. Safety Alert: The copper patina solution is toxic. Follow safety precautions, and always wear protective gloves when working with wood stains, solvents and other toxic chemicals. Ingredients: Ammonium chloride, 1/2 ounce Copper sulfate, 1/2 ounce Household salt, 1/4 ounce Hot water, 8 ounces Zinc chloride, 1/16 ounce Sawdust, 1/2-dozen handfuls, or enough to cover the copper surface of the project. Acetic Acid or vinegar, 1/8 ounce Mixture and application: Always add the chemicals to the water. Never add the water to the chemicals. Stir chemicals and water until everything has dissolved. Use a spray bottlewith water and dampen sawdust. Then mix the chemical solution into the sawdust (figure A). Save about 15 to 20 percent of the solution (to drip on and apply later). Spray water onto copper, press sawdust onto surface, wrap with cheesecloth, spray with water so that the cheesecloth and sawdust cling to the copper (figure B). Drip remaining chemical solution onto cheesecloth and sawdust and copper. Wrap with 4 mil plastic sheets (figure C). Seal with duct tape and set aside for three weeks. After three weeks, unwrap (figure D). Use water and an old brush to gently remove the crusty sawdust (figure E). Let the sun dry the copper surface (figure F). Finally, dab micro- crystalline wax onto surface (figure G) and let dry. Hope this helps.... there are pictures on site too if you want to see the process. http://www.diynet.com/DIY/article/0,2058,8966,00.html And some other recipes and info: http://www.sciencecompany.com/patina...naformulas.htm http://www.sewanee.edu/chem/chem&art...than/index.htm R |

R Thanks. Im thinking of doing a big garage door and wrought iron storm- securty doors, planters etc. That Modern Masters site shows large high buck projects in Vegas that look great. But with experimenting it could all look like crap when im done. |

R Jesus Christ, get a can of green spray paint for a dollar at Walmart and ten minutes later you'll have green copper, and you will still be able to breathe, and wont be filling the environment with tons of toxins aside from the propellant in the can of spray paint. Better yet, use the no cost, no pollution method. *DO NOTHING. In a year or so, nature will do it for you.- Hide quoted text - - Show quoted text - You dont know copper, maybe in 20-30 yrs it goes green, in the desert type invironments, maybe never. Green paint is green paint, some use it on their brown lawn, do you. |
