Acid
400ml of 85% phosphoric acid
400ml of Distilled water
Has been tested to work this morning. So if you don't have access to "DMB".
A drop of dishsoap would be good to reduce surface tension on the parts if you have complex pieces.

In Electroforming by Leslie Curtis she adds 3 drops of dishwasher soap to the eletroforming bath and say it stops bubbles from forming and pieces come out smooth and shiny.
This is awesome! Love your channel. You were my favorite professor and you're still a channel to come to. Great job brother.
Am addicted to your videos .. love them !! thank you for sharing!! xxx
This is a game changer! Thank you so much for sharing your wealth of knowledge!
Use lead flashing sheets used on roofs about 3/16 thick you could wrap the whole inside of the bowl
holy crap, i got sick of playing the brightener game in my first week, and now i've been putting up with dirty looking copper for like... the last 10 years! bro, you've sent my career in a new direction with this vid. THANKS A MILLION!
nice man yeah its awesome what he shows
Beautiful works, thank you for the information!
So glad I found you... I am gonna have a great start thanks to you
Are you freaking kidding me???? That's the most awesome idea you could have provided!!!! Gosh, I'm so thankful... Hmmmm, gotta go shopping tomorrow :D
this is a life changer, thanks
Fantastic! I'm not electroforming yet,..but I'm learning so much from watching your videos. Thank you for sharing!😊
Great Video and information. Thanks
That's awesome! Thank you.
Man O man im glad im finding you before ive really bought anything yet! You seem like me - there has to be an easier and cheaper way! Thanks so much and i still have so much to learn.
Hey Jason great stuff. I just finished my first electroplating project. I used your solution formula you sell on your site. (purchased other videos too, worth every penny). Despite your advice I started with a very large piece (needed for an art project I was working on). It was relatively low surface area 8 inches for it’s size 10 inches in diameter, but it was a large piece. I added
This works great at removing firescale too!
Awesome! Brightner is a pain in the ass. It's so expensive! Thank you, Jason!
WOW, a bit late for a comment but this is definately needed in the arsenal of processes. Thanks for that video and demo.
Super impressive!!!!
I'm definitely going to have to try that. I started watching your videos a year ago and have since gone from making rings to electroplating leaves and other plant things, to electroplating feathers to make dreamcatchers with them and leaves etc. I could never get my rings to seal good enough. Well good enough to me anyways. I used protectaclear according to instructions. Wash thouroughly, rinse in distilled water, denatured alcohol rinse, then seal and let dry. I do work on a farm though so there's always wrenches and metal cranks going around my hands. The finish would just chip off in a couple days and then start turning my fingers green :( Anyways back to the point. I've never used brightener in my electroplating. I just take the finished things out to the wire wheel on my grinder and polish them up that way. Trying to get into all the little nooks and crannies though proves to be a challenge and i end up finishing things off with a little dremel wheel. This method would be perfect for feathers and electroformed flowers and stuff like that.
Thank you for sharing Jason.
I’ve got a couple of pieces that got slightly rough and bumpy thanks to a minor contamination- I’ve used the flash bath to remove the worst of the damage ready to pop them back in the bath now it’s been filtered.
Jason this make me happy too LOL!!!! its so shinny!!! :)
Citrasurf (soap water citric acid )works well if you want a satin finish we use it in a passivation process
May be Citrisurf?
Nice!
Wow, that's like magic. You got me to try electroforming a year ago, with limited success. Lots of ugly pieces (a few good ones)...maybe this warrants a second attempt for me.
Hey Jason great stuff! …question follows
I just finished my first electroplating project. I PURCHASED and used your electroplating solution formula that you sell on your site. (I purchased other videos too, worth every penny). Despite your advice I started with a very large organic piece (needed for an art project I was working on). After I sealed it (dipped) with multiple coats of very watered down water-based lacquer, I used a very watered down version of your Modpoge conductive paint (1 part Modpoge, 2 parts graphite, 3 parts distilled water) as a two coat dip. Even though it was very large (10 inches in diameter) it was relatively low surface area 8 square inches) . I added extra anodes, and extra connecting wires to the piece. I hade to make a tank out of plastic animal feed pan. Otherwise I followed your instructions to the letter (one exception which I’ll get to below).
It was a UNQUALIFIED SUCCESS! It worked even better than expected. Thank you so much for your great instructions!
Now I’ll get to my question. I used the commercial brightener solution, and it turned out very shiny. But what if I didn’t used brightener at all? Frankly, for some of things I will be doing, I would prefer a matte finish. Would I be okay leaving out the brightener completely? And would I end up with a more matte finish?
BTW… the only modification I made from your formula was replacing the battery acid with full strength Sulfuric Acid Rooto Drain cleaner. I discovered I had reduce the acid content by about almost a factor of 10 to reach a PH level of .7 or above.
Thanks again for your great instruction. I recommend everyone purchase your instructions. They were worth every penny. I had the desired results on my first attempt at copper plating.
Oh how I wish I had found your channel when I was first beginning with electroforming. You’re a life saver for everyone who asks me “what’s electroforming and how can I do it?” I’ve always just answered “it’s science magic,” and they pretend to understand as I try to explain the process but... yikes. What you’re doing is amazing for so many artists out there!
I'd say "it's alchemy" butr nobody ever asks me ^^
One more question, why does it have to be Lead on the negative leads? This process is basically electroplating in reverse, as its removing the oxidation layer on the copper and depositing it on the lead, right? So couldn't other materials be used instead of lead? Or does the lead have some type of chemical reaction or "exchange" with the acid in the bath??
Any word on this? I don’t like lead
@@CptCrotty nope, never heard back. And I haven't done any electroplating in a while now.
it's because the lead oxide forms a protective layer (most likely im not a chemist), which means if left undisturbed it won't leach in to the solution or react, but like you said, it probably accepts that free radical that is coming off the copper? idk just guessing
Stainless steel or any other inert metal, works.
Hi Jason, could you share with us the ingredients and percentages that you use in your copper plating solution? I bought your recipe for conducive ink and would happy to do the same with a recipe for your copper plating solution
File down your "junk drawer" and flash em again for polished pieces with character
Greetings!
Great Video. How many drops of dawn would you use for one galon of solution (based on the 50%-50% recipe). thanks a lot.
A DC to DC buck converter would allow you to continue using the 24v power supply but adjust the voltage down and consequently the amperage according to the resistance of your electrolyte and plated parts and plates, and the applied voltage.
Hi Jason, could u guide me what should be current and volt used in silver electroforming on wax?
Oh no! I see another build in my future!!
Built it and works great!! I used a 1/16 sheet of lead.
@@odalaigh Great Job on answering yourself. Guess I'll do the same. Answering myself.
@@moonolyth do you guys know if there is a danger with this method and possible lead gas?
I'm really interested in the chemistry of what's happening here. I know Cu is being oxidized into Cu 2+ ions, and I'm assuming the H+ ions from the phosphoric acid are reduced and produce hydrogen gas that forms on the surface of the part. I'm trying to figure out what part the lead has to play in the reaction as well as why you use phosphoric acid rather than hydrochloric acid or sulfuric acid that produces more hydrogen ions.
Great process, could this replace tumbling? And it looks like a fractal at 17:25
Thanks a lot for sharing. Got some doubts, whats proportion of comercial phosphoric acid and destilled water we use for a e liters container, and I got that the negative pole goes to lead , and the positive goes to the piece we want to clean__
Merry xmas!!!!
Hey - great video. I just want to double check the ratio is 50/50 for this bath? And how do you store the solution?
Thanks for sharing, ... I'm pretty knew to this but have been doing my homework but I can't get the results you are getting on a freshly copper plated object. I can bring up copper coins to a mirror finish by dipping like you are doing in the video but my copper plated parts are making no difference at all, can you please advise where I might be going wrong here? ... I have been trying to make a shiny garden leaf, I put the conductive ink on it (dipped like you do) then coppered it, and it went on fine, coppered it at roughly 0.5 volts, all was good apart from trying to make it shine in this solution. I can't put a wire brush to it as it's to delicate. Look forward to your reply, keep up the good work ;-)
Well I can say it works for sure
Although I didn’t notice I needed to add water oops
Straight 85% acid with some soap
Hell it worked just fine lol
Amazing! Did you try with citric acid? Here in Spain is so difficult to find phosphoric acid. What amps did you set up?? Thanks a lot in advance! 🙏🏻
@@Calhiel no I didn’t try citric acid
Watch the video you can find it in some cleaners
Are the lead cathodes consumed at all during use? Do they need to be replaced. My metal supply house has lead sheeting which would have a large surface area.
A great technique, Jason! I going to try this out tomorrow!
Just a slight correction which has nothing to do with this process. The word "cathode" is pronounced "cath"- "ode" not "cath"-"rode". You pronounced it this way, twice.
It doesn't get the job done any better but while we are emphasizing this particular word...
If I electroplate a 3D printed mold in copper, would this process help remove the lines making a smoother surface?
My guess it would but at the expense of detail you want as well.
Let me know what you observed when you have a chance, please.
Great video. Thanks for sharing.
can phosphoric acid use for gold and silver polishing too?
Could you use parts from an old lead acid battery?
Jason, is it just the Phosphoric Acid in that combination or do you think it has a hidden "brightener" contained inside? I know it says brightener on the bottle but what is that "Brightener", is it just the Acid? I'm trying to find an alternative because I can't seem to locate the DMB in Fairbanks Alaska. My only choice is to find an alternative with as much Phosphoric Acid in it as I can.Thanks for your time,Chris
Awesome video thank you! Out of curiosity does the other material HAVE to be lead or are there other anode materials that can be used. Or is lead just the best performing? Holding off on my next eBay purchase for a response 😅
COULD you tell me what electrolyte to use or how can I get the liquid solution to do this process (EP) on titanium´s pieces? Thank you very much! I wait your response...!!!!
Jason can I use Aqua mix phosphoric acid cleaner substitute? Duda energy does not deliver to Hawaii.
I'm having the same issue up here in Fairbanks Alaska. Did the Aqua mix work as an alternative?
may i know dc power supply details .its how many dc output volt ?thanks sir
@Jason Welsh Great Video!! Thanks for Sharing!
Question, How about using the same setup, but with Citric Acid? Would it work?? I know people use citric acid, usually lemon juice, to clean copper cookware and etc. And its much cheaper than phosphoric acid. I have some powdered pure citric acid, i think I'll try it and see if and/or how good it works.
YHRIM did you try citric acid at all?
I'm interested in the outcome...
@Jason Welsh brilliant vids thank you!
Does it work on silver?
Does it work with other metals like silver or zinc?
I'm having trouble finding Hillyard DMB HIL0047406 in my little town. Ospho "rust remover with 45% orthophosphoric acid by weight according to msds" is available near by. will this work? Thank you for all your vids. They're awesome!
Does it work on Silver ??
Hey Jason, awesome video. Question for you though? You said the cathode is the lead. In standard electrolysis, a cathode is negative. Is this the case here? All clips used that I can see are black so I just want to be sure.
Yes, in this case this is like reverse electroplating but with the phosphoric acid making copper very bright
I like to see you electropolishing aluminum. I couldn’t get my aluminum to go extremely polished. In fact, they actually became cloudy looking polished if that makes sense. I’m trying to go beyond the next level of polishing aluminum, in terms of I already super polished the parts by hand and want to polished beyond that. However, I used Phosphoric Acid 75%, no water mixed. Voltage ranges from 12v to 20v, 1a to 5a. I was only able to super shine silver and chrome. Mild steel and aluminum didn’t turn out good, they turned out flatter, not shinier. What am I doing wrong? I’m trying to electroploish aluminum.
Hi, how did you polished the chrome?
About aluminum i think it needs sulfuric acid and glycerol too at 2AMp 3 to 6v
Computer power source, buy cheap at goodwill, 12v, can take all yellow wires, bundle them in a lug, all black wires and bundle in a lug, and get 12v out. Theres a 5v source in them, too, red wires? They come 145w to 500+w. Thank You for this, too 🙏⚒️⚕️🎵🎶 ~C< 3)>>-Z->}
Hi Jason, would this work with nickel plating?
Did you ever try this for nickel? That was my question too, but this guy never answers anybodys questions. Thanks
Is this adding or removing copper ?
Removing
What is the Voltage and current settings?
24 volts 15 amps
Don't keep your junk, make it the sacrificial as long as the base material doesn't contaminate it. Leaves are fine, nothing happens to the graphite paint. You could redo them (I don't) if they are not what you want.
Has anyone had a problem with fumes?
Why the all but non conductive lead weight?
My first guess is, it reacts with the acid mix less than would other cathodes. Too, I'm guessing a positive side effect, when using your high voltage computer power supply, it would act as a crude dropping resistor, to reduce the voltage.
All that aside, thanks for a great tip.
As an aside, I've rescued a few of my oops projects by tossing them back in the plating/forming bath and cranking up the voltage to let the current and bath have its way. I've ended up with prized projects.
Can you use this to polish nickel plating ?
Would also like to know. May even try it myself and see.
"What's a 'cath-road' Walter?"
“It’s DC voltage so it doesn’t hurt but it is painful” enough with the chemistry, show us how you grow your weed!
Does this deposits lead into the water?
No, it's the copper from positive anode (electropolished item) that goes into solution.
All it’s doing is removing a thin layer….just immersing in white vinegar for a couple of hours will do the same…then it polishes very easily..with a soft brush..
Using your method is faster, but more expensive and quite dangerous using 10amps….but it will soon tarnish back to the dull colour
Are you sure about this?
could you use coke ? ?
There's nothing dangerous about a 24 volt supply, regardless of it's current rating.
At 15A, thats 360W of power... please don't spread such dangerous nonsense...
@@VonDerHeideblume You're speaking to an electronics engineer. If you believe you understand electricity better than me, then you are deluding yourself. 24 volts will never pass more than microAmps through a human body unless you've either been soaking in salt water for days or hooked the power supply to needles and stabbed yourself with them. Other than that, a 24 volt system will never be able to apply even a single watt across the dielectric of intact human skin. Even if you're talking about the dangers of that much power turning a motor it's still nonsense. Even moderately fit humans can produce peak outputs of over 400W of mechanical power.
There is nothing, ABSOLUTELY NOTHING, frightening about a 24V power supply. It doesn't matter if it's capable of producing a trillion amps if it doesn't have the voltage to push even one milliAmp.
True, under 'normal' circumstances that might not be a problem, you can touch both poles of car battery and won't die, BUT if you are grounded by some happenstance and have reduced skin resistance it MIGHT lead to problems. But you are right, normally 24v is pretty safe to handle but with the right (or better wrong) circumstances it can be dangerous and lead to injuries (same goes for handling strong acids). All I want to say is don't play down the risks, especially to people who are not familiar with the matter.
So KFC style...'extra tasty crispy' to be more exact?!
Should try it with diet coke and detergent
Does this create the same effect?
@@driajean3542 The joke is about the Phosphoric acid in Coke, it is there to make you thirsty soon after drinking it.
CATHODE not cathode. There is no “R” in CATHODE! 😊
Ps it does make a bit of hydrogen gas so don’t put a flame to the soap bubbles
They go BOOOM lol
Ask me how I know
Very cool stuff, my partner is a long time follower and we have learned a bunch from you sir.
Legit question. The lead. If a peice is going to be worn, next to or near skin. Will that cause problems or not, and why? Also, what can be done to mitigate any possible issues?
