It works by the simple chemical reaction where the Copper in the copper-sulfate replaces the metal being etched which changes it to the metal-sulfate and generally goes into solution and is washed away. If you now remove that deposit of copper you will be left with a hollowed out etched surface or in some circumstances the copper plating. When you are working with a copper alloy such as bronze and brass the copper content is unaffected and the other alloy metals in the alloy are reacted on and dissolved by the copper-sulphate, hence the apparently random surface effect. Knowing that this way will produce the etching process that the electrical etching system relies on, why would you bother with electrical etching. In effect the copper-sulphate does the job of the electricity.
In your description it would be nice for you to put a little bookmark for each metal that you did, so if someone wants to see a particular metal only, they can just click on the time and it goes srmtraight to that point. Great videos
I'm betting if you abrade zinc galvanized steel down to the base steel that when sprayed, you'd get blackened finish on the zinc and copper finish on the steel for a nice visual effect!!!😁👍🏻
Matter of taste I guess. I build guitars and want to buy a desktop cnc mill and make my tremolos out of brass. Now brass polishes up like gold. But then after just a few weeks of heavy playing and sweating my tremolos will look like your patches. I’ve never electro plated before but I’m retired and have plenty of time to perfect it.
Are you wanting them to stay like polished brass? I am no expert on guitars but it sounds like you need a good clear coat to prevent oxidation. Give us a call and we can help you walk through how to achieve your desired finish 760 432 8242
It causes a reaction on pewter but we do not have it included in the video. Email or give us a call and we can make sure you have the best product for the desired finish you want to achieve.
Off topic, but I found this clip hoping the copper sulphate might turn the metal Blue or purple.. With heat, is there a chemical that will turn metal a cobalt blue type colour?
Hi, I tried copper surface on mild steel and although it produced a beautiful copper sheen, it wiped Strait off. Is it possible to treat it in such a way that the copper look stays? Thanks for your advice.
Copper Plating might be better for you instead of Copper Sulfate. Another thing it could be was how you cleaned your metal. Give us a call and we would be happy to help walk you through it. 760 432 8242
Might be a tad misleading there, this video shows what Copper Sulfate does on all metals that it works on. It does nothing to stainless steel, but most patinas wont do anything to stainless steel. We have specific ones that will however, take a look at Slate Black and the Stainless Black if you are interested in that.
@@sculptnouveau ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-GndpMH2vKaw.html I think that's the clip you mentioned. How about Chrome? Will Copper Sulfate work on Chrome?
Copper Sulfate does not work on aluminum. What kind of finish are you looking for? A14 will go black and Slate Black applied hot will give you a brown finish. Otherwise, faux finishes are likely your next option.
What is the concentration of water to copper sulfate? I need to do two sheets of copper 12x60". My husband is not keen on me using a torch; a downstairs neighbor used to forget stove so kitchen burned. No creme brulee for us, sigh. He might let me have a hot gun. Do you know if those get hot enough?
This Copper Sulfate patina comes ready to go, no dilution required. You would need two 8 oz bottles, though I would recommend getting a 32 oz bottle to ensure you have enough. It depends how thick the metal is. The thicker the metal, the harder it will be to do with a heat gun. Thin material might work though.
