- In this video, we cover using Black Magic on steel and basic metal preparations for cold patinas on steel. This video highlights the use of Black Magic but these steps are easily translated to also be a good tutorial for Slate Black and PC-9. Black Magic can be found at: www.sculptnouveau.com/Details....

Hey- so I understand that there is a film that must come off during the rinse, but how hard do you really have to work to rub it off? Seems like it needs more than a gentle cloth or sponge. When I continued to add more coats the black even flaked off later during the rinse, which I'm assuming was built up residue. It seems effortless in this video, but in reality it seems like I'd need an abrasive to get it off. Any advice from experience is much appreciated!
It really should come off easy, sponge or rag is all you need. If you use an abrasive, you will start taking off the patina. Give us a call and we can discuss more about it - 760 432 8242
This sounds really cool
Hi, I'm confused. Your vids show a spray bottle, but your website shows a bottle. Also, I am looking to do 2 file cabinets 15x30 30 tall with no tops. How much would I need? Thanks.
The 8 oz and 32 oz comes in a bottle with a sprayer that you can attach. The gallon does not come in spray form. An 8 oz bottle would cover about 8 square feet, if you want to do multiple coats consider a couple of 8 oz bottles or a 32 oz bottle.
How does this compare with something like gun blue? Black Magic can only be ground shipped so it is unavailable. I am planning on creating a patina on a drop-forged axe head, not a smooth surface like the plate here.
Black Magic is more of a charcoal or grey black, usually it doesn't get a blue hue to it. If you want a gun blue, most people get PC9 under the Birchwood Casey section on our website. We have gotten our certification so Black Magic can be shipped via FedEx Air now. Black Magic works on forged pieces too, not just flat sheets.
Are there any food-safe equivalents for these products? As in black steel kitchen counters?
We do not have any food safe certifications. For kitchen counters however you should only need to seal them in. If you have metal counter tops you should not use them for cutting or preparing food on it directly anyways.
Wonderful Site. I am interested in using mild steel panels (4x10)instead of weathered steel for exterior cladding and I am thinking about scaling up the process you have outlined here. Do you think this approach (primarily for savings) is feasible and/or advisable. Would you treat the sheets as per one of your processes or just let the weather do its magic. Thanks.
We have many customers who use our products on large scale projects. If you let weather and nature take its course on steel it will rust. If you want it to blacken, then Black Magic is one of your best options.
how does mill scale affect the patina process and when do you remove it? i usually use a wire brush wheel to remove the mill scale
Mill scale acts as a barrier for the patina, essentially the patina cannot react with the steel due the mill scale. Typical removal takes place prior to patina and degreasing though for best results: degrease, remove mill scale, then degrease again.
I am looking to purchase two copper gas lanterns. Is there a way to guarantee that once the patina process is finished, the lanterns will look black? I've heard that the color varies with the patina process, sometimes looking grey, brown, or black. I want the lanterns to look like an aged black lantern. Can a dark black patina be achieved by repeating the process more times? It looked like that was possible after watching your video. One more question - Once the dark patina process is finished, will the lanterns stay that exact color or will they continue to change color over time?
Might be easier to discuss over the phone to get more in depth but I can answer your questions here first. Choosing the right products will better your chances of achieving your desired finish. For Copper, I would go with the Birchwood M24 instead of Black Magic. The more coats of M24 you apply, the darker it will go but you will need to dilute the M24 before starting to ensure it is not too strong of a mix. A 3 part Patina to 1 part distilled water is your best bet for a dark finish. You can also apply Black Patina Stain to help nudge the color darker without needing to do another coat of M24. You will need to seal in the finish in order to keep it the same over time. Without a sealer, nature will take over and can make it change.
Thank you for this video. I am new to metal art, and, trying to study it by myself, following you on you tube and others. thank you again
i understand how this works on a small piece o a few square inches of work but how can you do the same thing on a piece that is several square feet?
This is just the basics video, take a look here to answer your question: czcams.com/video/z0SM7M3FUP8/video.html
Can you Mig weld to steel with the patina on it or does it need to be removed first?
You should be able to weld through it but it wont look pretty anymore. I usually do all fabrication first, then patina.
Can you use oil in place of the clear coat?
Yes, though it will normally not last as long as a clear coat. It will need to be reapplied overtime, like the wax needs.
Hi! Do you have a black magic that will work for Tungsten?
Unfortunately we do not test on tungsten metal so I am not sure which would work best. If you send us a piece of scrap tungsten I would be happy to run some tests to see which might work best. Email us at info@sculptnouveau.com if you are interested.
Instead of sanding, can I sandblast hot rolled steel and then apply?
Yes!
is this the same chemical process as bluing? I am interested in making a homemade blackening/bluing patina on steel. Can you explain the different chemical processes please?
Similar process but not the same. Most people use the Birchwood PC9 for a bluing patina instead, it is a bluish black finish. sculptnouveau.com/collections/birchwood-patinas/products/birchwood-casey-liquid-patinas
Does anyone make metal blackening for chrome?
You can use a non-reactive finishes such as Smart Stains or Patina Stains but we do not have a reactive patina that blackens chrome.
Hi, Im interested in using this to darken steel on metal joinery for doors and windows. Does it work well if applied to a vertical surface and would I have to take care of the glass?
It does work well vertically but I would try it with the Patina Gel to make life easier: czcams.com/video/RpVHzP1KQiY/video.html
It should not do anything to the glass but you can do a test to make sure, or just tape it off just in case.
How would this hold up in a cafe setting? I am looking to redo our stainless countertops and they need to be able to hold up to a lot of abuse.
Black Magic wont work on stainless steel. You would be better off using the Stainless Black patina with the Ever Clear over it for protection.
Do you need to use the metal cleaner in between coats or just the water rinse?
Metal Cleaner is only used in the beginning prior to patina. Use water between coats.
does it works on 316l steel?
No, for stainless steel you need the Stainless Black: czcams.com/video/YwasGr-h-LY/video.html
Will it affect nickel for damascus purposes?
We do not have nickel on hand to test on but I tried it on an actual nickel and it did blacken it.
If Im using this on a large piece, can I rinse this out on my driveway/street?
You should collect the run off. I usually will use a kiddie pool or a bucket of some sort. It will evaporate over time and then you can wipe the residue out and throw that away. Take a look in this video for bigger Black Magic application: czcams.com/video/z0SM7M3FUP8/video.html

Is it possible to find Black Magic in Turkey?
Unfortunately Turkey is one of the few countries we cannot ship to and we do not currently have a distributor there.
does this work on bbq pits?
Yes, though longevity comes into question due to the heat. Try using a clear coat with a high heat rating, something like engine clear coat. That will help the Black Magic last longest.
Does the metal have to be completely free of any paint? Could you use it on a black car that you flattened the paint with wet & dry?
The Black Magic will not work if it is not in contact with bare metal. I am not sure that I understand your question completely though, give us a call and we would be happy to help you with your project. 760 432 8242
Will this work with titanium
I have never tried. If you want to send us a small piece of titanium we will test which patina will blacken it for you.
Sculpt Nouveau Did this end up happening? If it did, I’d be interested to know what you found?
@@connor_____9236 Unfortunately not yet
How well does this hold up outside?
+Bert Gilbert Black Magic is a strong finish but it needs a clear coat to keep it from rusting. For great protection you can use Ever Clear.
@@sculptnouveau What kind of prep must you do before applying Ever Clear over black magic? Would the SN Degreaser/Cleaner strip the patina?
@@tE.23 After applying the Black Magic, just make sure it is neutralized well and completely dried. No need to clean prior to Ever Clear otherwise.
Will this work with stainless steel?
Unfortunately no, you need to use a patina designed for stainless steel. Try this one: czcams.com/video/1_3mv_rhV9U/video.html
@@sculptnouveau thank you kind sir
Can we brush to blacken
How ever the patina gets on the metal it will react with the metal. Brush, roll, spray; they all work but they will show characteristics of application.
Will this work on a galvanized metal?
Not in the same way as the video. If you want black on galvanized take a look at Antiquing or Zinc Grey instead.
"The finer grit sandpaper the harder the patina has to fight to get its patina on the surface" - so if im understanding this correctly a 220 grit sanded piece would have less patina than a 120 grit sanded patina?
Not necessarily. What I meant when I said that was that the Patina might have a harder time biting and holding onto the metal when you use higher grit sand paper. So a patina will grab and hold onto the metal better if you used 120 grit rather than 220 grit. Not so much dealing with the amount that holds onto the metal as much as with the higher "polished" surfaces the patina might not be able to stay on the metal when you rinse it.
what steel did you use??
This was a sheet of cold rolled steel. Hot rolled steel would work as well though the mill scale will need to be removed for it to work properly.
Do you know the compassion of thes steel?
Black Magic works on all non-stainless steel alloys as long as the mill scale has been removed and it has been cleaned properly.
@sculptnouveau what would you suggest for a large section of wrought style railing? Would mill scale end up rusting or just give an inconsistent patina finish? Sandblasting isn't really and option. Railing is indoors.
Thanks.
