This formula will yield an electroforming bath that cost hardly anything in large batches.
Copper Sulfate Bath Formula
For 1 gallon of distilled water-
32oz. Copper Sulfate
32 ml. Sulfuric Acid
10 ml. Brightener - แนวปฏิบัติและการใช้ชีวิต

Benzidine and Sulfuric acid are listed as active ingredients in Midas Brightener. Benzidine simply stops oxidation from occurring on the metal surface which adds an extra shine to the metal but must be acidified in solution with Copper Sulphate Pentahydrate in order to work. Benzidine is nasty stuff - Highly toxic and carcinogenic. I find using glacial Acetic acid (photography supply house) rather than Sulfuric acid yields better and brighter results on my electroplating. Just substitute glacial Acetic acid for Sulfuric acid and see if you get good results. I also filter my Copper Sulphate solution and you'd be surprised at some of the impurities I've found in that Zepp root kill! Sulfuric acid is an oxidizing acid and when it is excess in solution it can have a negative effect on the lustre of the copper crystals that form during electroplating.
Thanx for taking the trouble to show us Jason..bravo Zulu..Jake Oz cheers
I see there are several inconsistencies in your recipe quantities. Can you just put a formula at the top and make it sticky. It seems sometimes you give quy for 1 gal and sometimes for 2 qt.
Thanks very much for this informative video🙂
Just recieved the last ingredients ( brightener ) . Will be making my first tests in a few hours . Thanks for helping , dude !
love ur vids have u ever heard of using mollasses as a brightener
SO what makes the new formula 1000x better?
Jason, do you know anything about adding benzidine compound and sodium potasium tartrate into the bath instead of using Midas Brightener? I have been trying to figure out recipe for brightener and these ingredients are listed on Midas Bright Copper Plating Solution MSDS. Just thought maybe you might have tried this or know why it is included in the Midas Solution. Thanks! Jamie
For brightener, study United States Patent 2391289 by John F Beaver. Unless you're going to plate a LOT of material, it wont be wise to try making your own brightener unless you can order tiny quantities of those chemicals somehow.
To find out what is in Midas check the MS safety sheet
This recipe uses the 65/35 water/sulfuric acid that comes in standard battery acid, correct? you don't need to factor in the amount of water already in it?
Can you use virgin sulfuric acid (liquid lightning drain opner) and if so do you need to add more or less or the same amount?
Hello from Tokyo Jason, I’ve gotten my hands on 0.5mol of Sulfuric acid, what is your recommendation on mixing with distilled water?
How many parts of 0.5 mol to distilled water to get a safe somewhat safe but effect level of acidity for the solution before I dip my nickel anodes?
Hey Jason how's it going been watching your vids lately and I wanted to say what a great job you do thx a lot they've helped out a lot. Anywho I just made my first bath a couple days ago I made it with every you have in this vid 2 quart amount my question is I made my brightener with the miralax I found at home it's a year expired but I did some research I think it's ok to use for a purpose of this type not to take orally so question is how do I still use 30mls for 100lm of distilled water? And is that amount enough for a 2 quart bath? It's not in this vid but another one of yours when you show us another way to make brightener besides using midas. Anyways any help would be great thx again
What do I do with my bath solution when not in use for a couple days?
Hei Jason, do you use the same amounts for electroplating and electroplating bath? It has no differences?
So, does it mean that electroplating is just a matter of adjusting a lower current in the power supply? Thank you so much, and lovely work!
For what I know brightener is just pure sulphuric acid and some copper sulphate?
Hello Jason I have but one question can I get a link to the place that sell copper gleam pcm+
How much it will long on surface of plastic utensil used for water storage??
how do you know how much water to add?
If using 94-98% Sulfuric compared to the battery acid 34-38% strength. How much 98% would I need in a batch?
For the brighter try Polyethylene Glycol...Clearlax (Walmart) or MiraLAX
How do you add the powder to the solution? Do you dilute it in distilled water? And what percentages do you use? Thanks
@@mireiarocabel3275 Polyethylene Glycol? How much you have to add?
Might be a dumb question but what can u stir with if it’s not a glass rod ?
Nice video, What would be even nicer is if you could show us a finished quality item.
can you show us how to make brass solution?
Hi, how much brightened did you add to the 2qt solution?
Do u know how to make gold plate solution?
Thanks!!!!
Love your voice
Thanks! I love your face 😻
how to get the acid out of the battery..... it's a sealed unit?
I wish you'd explained at the start if there is or not a difference between e/forming and e /plating solutions
Nice vids on your electro forming experiments. The new brighteners are usually proprietary exotic chemicals. No idea what's in it. But if you look a bit back in time people used simpler stuff that also worked. I found reported use of saccharine(artificial sweetener, use 0.1-0.5g/l)as brightener, triethanolamine works as a leveler, reducing dendritic growth(3-10g/l). more modern formulas use (polyethylenglycol, molecular weight 1000-3000) and a bit of "Janus green" which is a special dye used in microscopy. No measure g/l given. In literature. If you feel like experimenting you can try small batches. Just do a bit research yourself using the above mentioned chemicals in conjunction with copper plating as search terms. For real thick electro forming the oldsters used periodic current reversal with the reverse always shorter than the forward. E.g. 8sec forward(that's what you do now) followed by 4sec reverse, where the ring becomes the anode and material is actually removed. Can be done easily with a timer and a few relays. Reason behind it is that during the de-plating phase mainly the high spots on your object are eroded so overall you end up with a more level surface. This technique is still used today, they just call it pulse/pulse reverse method and use fancy electronic to periodically swap +/- connection. Good luck + have fun!
Many recipes have a bit of chloride in there, as well. Polyethylene glycol aka PEG is readily available as PEG 3350 (average mol weight is 3350) aka restoralax. Myralax etc.
just a reminder that if you have a firend that knows arduino electronics, they can easily do that for your
Hey there! Love your videos!
I am wondering.. I’ve now mixed the solution twice, and my pieces are coming out of the bath very dull.. I have put in the mirilax for the brightening agent. I followed the steps and I’m just not sure what I’m doing wrong..
Hi there! it really depends on your pieces surface if its shiny or satin type try to use metal polish after it dried then youll see the real results.
Do you have the next step?
Good thing it needs "hot, boiling water", as I have trouble keeping cold boiling water in the same room as me.
Hi Jason! Thank you for this tutorial and for the one on electroforming jewelry complete breakdown, they are both very useful and well explained for beginners like me. First question is - will the electroforming solution work without the Midas brightener? I live in Europe and they don't ship hazardous items internationally. If I don't use the bightener does this mean I should have to prepare new solution after a number of uses? My second question is: the bath quantity you prepared in this video is enough for several small pieces/rings (say around 7 to 10) electroformed simultaneously? Or should I prepare more solution for multiple pieces? Thank you!
The bath container I use actually holds 1 gallon, (2 batches of formula that i showed in this video) I can fit 15 rings at a time in the container. The "brightener" has been looked at by many people but the formula is still lost to me. i have tried about 12 different combos of chemicals but still can formulate it. Do you need it? No but all your pieces will need to be buffed. So buy a good buffer!.... You will need one anyway!
I ordered your new formula but was not asked for my email that I saw. How do I get the formula to my email?
Thanks for the great video. I have a question for you. When I do electroplating it always turns out very dull what am I doing wrong. I am not able to get battery acid where I live. 🇨🇦 nobody sells it !!
try autofactors, motorbike garages etc.. its used in car batteries, you can buy the liquid or just buy a new battery and carefully pour it from there.. that, or buy it online
Thank you so much for making these videos, i keep going back to it. Also please make another video about properly storing these chemicals ( Battery acid etc, once i opened them i dont know where to put them lol )
hey , is there a reason you put boiling water instead of room temp water ??
and can you please write again the measurements because you wrote 32oz copper sulfate but you put only 16oz in the video or am i wrong ?
and how much battery acid ? you wrote 32ml but in the video you put 60ml ??
hoping for an answer !
Boiling water instead of room temperature to dissolve the crystals and I'm assuming he just doubled his original recipe.
Your camera is too good. It's like your hands are right in front of me. Never thought I'd see the day when i wished for lower fps.
Hi Jason. I'm a new subscriber and really like what you are doing.
Just pointing out you are using a recipe in imperial units then you add acid using ml.
I did a conversion in oz but it came out 10x off as if your measurement converted to .5 oz and it appears you put 5 oz in your mix.
Could you clarify that? Also it helps if you stick to one measurement system...
Thanks for sharing the information though.
the video and the description are 2 different recipies, one makes a gallon.
Do you have a video on silver plating ?
Midas is not available in my country (the Netherlands). Did you meanwhile discover how to make it?
you can order it at tifoo in germany i think
I am about to try your solution. Is this correct? Can I use a wooden rod to stir this? Once it is cold do I still need to worry about fumes, I will be making outside then bringing into the garage for plating.Copper Sulfate Bath Formula
For 1 gallon of distilled water-
32oz. Copper Sulfate
32 ml. Sulfuric Acid
10 ml. Brightener
Is this the electroplating or electroforming solution?
Could you please help me to convert in into metric (litres and grams) please? Struggling with imperial units...
jezus: just google gallons to liters and oz to grams...
Thank you so much for your video! Would I be able to use the acid out of an old car battery? It's really hard to get here in Australia. Wondering if the acid would be clean enough? Also, if I can get 98% sulfuric acid, what amount should I use? Thank you so much for your time :)
anyone know of any art and craft schools in US that offer electroplating?
I have a jimmy rig setup, trying to figure why I'm getting more of a rust looking paste then plate. Any ideas?
Too much voltage too much current possibly. Whats your jimmy rig consist of? The Current and Voltage is really important to be able to be in control of. You can buy a nice power rectifier for rather cheap on the interwebs.
That may also be caused on the metal you're trying to plate. Anything containing iron will produce a pasty copper coating as you describe.
Midas Copper brightener solution according to the MSDS........ - Cupric Sulfate - Sulfuric Acid - Benzidine Compound - Sodium Potassium Tartrate - ............ Just thought I would let you know ;-)
How do you top it up after it evaporates out? I have been putting distilled water in but now I have bad conductivity. Someone said to add salt in but I’m not sure.
Add more solution and not just water.
Jason...My electroforming copper bath is cloudy. Been sitting a few days in a chilly room. Any advice?
That's because the solubility of the copper sulfate decreases as the temperature drops so you got crystals forming. Keep the solution warmer or add water. That should most likely solve your issue.
I cant get the riograde cuz I’m in Canada what else could I use ? I heard miraLax works just as good ? If so how much would I add ?
A recipe I found says to add 1/2 teaspoon of the miralax
Hi! I'm having some questions: sulfuric acid is quite toxic and dangerous, so how do I treat the piece after the bath? is it enough to rinse it with something to get rid of the residual acid? What exactly is the acid used for? Is it possible to use something different? I was wondering how that works, after all especially if you are creating jewllery, the skin would be in contact with the piece for quite a time while you wear it, so you have to take special caution. Love your videos, by the way! Thank you!
dip in baking soda bath
The brighter is Polyethylene glycol the same stuff they use in E-juice vape pens.... I'm 99% sure
ZEP is $13.98 per 16 oz. at Walmart. You can get pure copper sulfate on Amazon $19.95 per 5 pounds.
Are you sure what you measured out is 16 ml? It looked like more. But, on the plus side, I'm sure glad you measured out the acid off-camera. I would hate getting that shit in my eyes.
*A quick search revealed*: a brightening additive to electroforming electrolytes is...
Ethylene glycol (anti-freeze). Serves as a surface active agent (surfactant). It lowers the surface tension at the metal interface, and allows the metal ions to migrate closer at surface.
One more source of EG is...MIRALAX, which contains as its chief ingredient -EG.
Another additive for brightening, performing the same function of allowing the metals to form a tighter plating, thus brightening, was...drumroll..Blackstrap Molassis. No, I'm not kidding.
You're welcome.
Polyethylene glycol in the form of laxative is much more concentrated. You only need about 1g/L, or even. 2g/L at maximum. Too much surfactant can result in a finish that doesn't stick well, and prevents efficient transfer of ions, resulting in a lower bath efficiency, and a lower plating efficiency.
What you need as a brightener is something like saccharin.
Look up the molecular formula for PEG 400, ethylene glycol, saccharine and molasses. All possess multiple OH groups. Use your imagination. I’m sure citric acid and maybe a sugar would work well too.
Ordered your recipe just before the change I think and trying to find it in my email. Can you tell me sender or title to search in my email? Trying to start my bath fresh again
If I do not have a glass stir rod what is the next best thing to use???
as long as its not metal it should be ok. Some metals will dissolve into solution contaminating it.
for the polish (Laxative / Polyethylene glycol)
I am trying to source the Midas brightness refresher in the UK with no results. Can anyone help or tell me an alternative please.
Maybe you can Get www.riogrande.com to ship internationally
Gateros sell a brightener. They sell all sorts of stuff for plating and electroforming. www.gaterosplating.co.uk/copper-brighteners
thanks that helped me a lot
Is copper sulfate pentahydrrate the same or a different thing? Where can we find battery acid I can't find it anywhere 😁
6 months late to answer but maybe someone in the future can benefit. Yes copper sulfate pentahydrate is the same thing. Just copper sulfate with some extra water in the structure, nothing to worry about in this situation.
I bought my battery acid at a local auto parts store. It took a couple of calls to find a store that had it but some should.
I have a question here.. Does Muriatic Acid also work as a substitute for sulphuric acid??
No muriatic acid is a dirty version of hydrochloric acid and has nothing to do with sulfuric acid whatsoever.
Thank you for this video Jason! Super helpful. Do you think it's possible to use Hydrochloric acid instead of sulfuric acid? Sulfuric is impossible to get in Sweden so I'm stuck atm
Sulfuric acid is a strong proton donor, that is why it's used in electroforming. Battery acid- All cars need it ;) You can find a 1000 how to make sulfuric acid videos on youtube but you will need to dilute it if you make it that way. Maybe you have the ingredients in Sweden?
Thanks a ton brother! I'll try to get a hold of a car battery and drain it :)
You don't need acid. This is the first person on you tube that said you need acid
Maybe it works better I'm not sure but I do know you can do it without acid and it works fine
Erik Kylander Hør på Biltema ;)
Most copper plating brightener mainly comprises of copper sulfate, zinc sulfate, sulfuric acid, saccharin, citric acid, 2.4-2N methyl-pyridine, and lead acetate .
What is the purpose of lead acetate and citric acid in copper plating bath?
Hi love the videos! I have two questions:
is 99% copper sulfate sufficient or does it have to 100%?
How do you clean the cup after you use the batter acid?
Thanks again!!
It will evap out of the cup, I only use that cup for Sulfuric acid and nothing else. Zep has 1.0% of "other" 99% Copper Sulfate and it has worked flawless for me.
It probably won't make a difference in 99.5% of applications but if you must have extra extra purity, you can recrystalize the copper sulfate, once or twice. Recrystalizing tends to keep impurities out of the new crystals, and concentrats the impurities in the remaining solution.
Again, probably not needed.
you can skip the hot water if you have time to let it sit. the lazy method is to dump everything in and let it sit for around 10 hours
what"s the cornstarch for? :)
He makes molds with that for copying items with electroforming, see the other videos.
el ácido ulfúrico es al 98% o al 35%
Video description says 32ml of acid but you put in 16 or at least you said you did.,
The video description is the recipe for one gallon of Copper Sulfate Solution, while in the video he only produced 2 Quarts of the solution. It was confusing as hell for me as well lol
People on other channels just use powdered laxative as brightener 😃
Never mind found the formula
Where can you find the battery acid?
any automotive store... bear in mind a quart is about $20 and 5 gallons is about $35...
you say that you are putting in 16 ml of acid, but looking at the cup at 1.47 and looking at how full the cup is at 6.04 then id say you are putting closer to 60 ml in the mix.
Did you ever get a reply on this? I am thinking he must mean 60ml but don't want to screw up my batch by using too much
Maybe the acid is low conc. and to get 16ml of acid he puts more diluted acid.
@@SashaCrow he's definitely saying 60ml
Jason, I'm just getting into electroplating my 3D prints (the materials are on the way from Amazon) but I do have a concern. What is the correct way of disposing of this? Any advice you could give would be greatly appreciated!
That's what I've been doing! I've been plating without the sulfuric acid (it's slower, but works), and the copper sulfate itself is root killer for septic systems, so just flush it. I don't have the brightener either, as in another video, he points out that MiraLax laxative will work. So that's two things designed to be flushed down the toilet, lol.
If you do use sulfuric acid, baking soda should neutralize it enough to be plumbing safe. Of course, most pipe decloggers use sulfuric acid, so you can flush that as well. Really, unless you're dealing with nickel plating, these things aren't terribly toxic. Heavier metals like nickel can lead to long term heavy metal poisoning. Copper can give you headaches and cramps. Copper plating is alot safer then one would normally assume. Kids do it in high school. Unless you're dumping more then 1 gallon a month, don't worry about it. More toxic stuff comes out of your body every day.
Can I make the mix with 50% sulfuric acid instead of 35% battery acid? And if so how would this affect the dilution? Like if 35% is used for your rate
32oz. Copper Sulfate
32 ml. Sulfuric Acid
10 ml. Brightener
Then would I just use less then the 32ml. And if so do you know how much?
Any help is much appreciated. Also, thank you for making these videos. Making my own conductive paint has been the best, now onto the next step.
You don't need acid
Everyone needs acid. Mmmmmm acid. yummy. All the pros use acid. What is your revolutionary theory here? I got the impression that no acid makes for massive inconsistency.
You kinda do need the acid. It adds another strong electrolyte into the solution, makes the solution acidic which has been tested to produce better results, and it stops the hydrolysis of the copper sulfate.
Is that 16 ml or 60 ml of acid?
8ml per quart
Thank you. In the video you added the full cup (60 ml).
The formula is:
42% sulphuric acid
26% Nitric acid
Water
How will that work. Could you explain? Nitric acid vigorously dissolves copper and produces horrible nitric oxide and nitrogen dioxide fumes.
copper sulfate look like blue meth
