Dude, i love your responsibility and sensitivity to your audience! Been watching since the glow sticks videos! Cheers

Thanks for the education! I came across your video via a coin community link. Glad I did! Very well explained, demonstrated, and responsibly caveated.

Amazing stuff man I'm just imagining like what woman does not want some pretty blue purple rainbow silver coin in her purse when we switch back over to the hard currency it's going to be an emotional thing to both give and receive for whatever the work is it makes more valuable the moment of your life.

Im super happy that you took my suggestion for redoing anodizing!

I loved the disclaimer of coins value 👍 love the video as always

Can you make a video series covering how to handle different kinds of waste materials? I know you do in different videos along with the reaction but I think it would be cool to explore the chemistry behind how Halogenated solvents are destroyed in strongly basic conditions. I assume it’s would be because the strong base would be acting as a nucleophile??? Anyways would love to see different kinds of wastes and how they are handled!

FANTASTIC!!! Thank you SO much!! This was super educational, and fun to watch beside!! New to silver stacking, and trying to learn all I can! This was about the 3rd-4th video on removing tarnish -- and it is AMAZING!!!

I am actually watching this on a 4k TV, really amazing!

That was fascinating my friend, very cool indeed!!!

Thank you so much for the explanation of the chemistry. Was wondering how it happened because I have coins that have that tone to them but did not do it myself... Now I know how it occurs...thx.

I'm in the "Artificial toning is bad!!!" camp, but thoroughly enjoyed this video and seeing how it is done.

NurdRage thank you very much for this update on the chemical reaction! Love the original video! It helped me a lot.

Calcium polysulfides are used as a contact fungicide on dormant peach trees. The common retail label name is "Lime-sulfur spray", old timers make it by boiling sulfur lime and some wood ash over a fire outside. Application stinks but it is very effective for peach-leaf curl (with repeat applications water resistance is low) and listed organic as it quickly breaks into plant available mineral nutrients in the soil.

Thank you for adding the part about coin collecting and how this is for science only.

Amazing people are finally making videos on this, still just for kicks obviously you could tone with liver of sulfur a lot faster, more controlled, and cheaper. I get triple over spot for coins but i do a really good job toning, better than a painted piece people pay for or a black ruthenium plated kennedy. Even the rio grande jeweler's catalog sells kits to plate silver coins in any combination of metals possible.

Amazing effect on coin

Easy to understand and very good information

I believe the fix was a misuse of a electrical term, and it's all good now :) so I won't say more. Thank you very much nurdrage

Big respect for the warnings

I'm glad I found Mr. Nurd cause chemistry is not my strong point.

Very helpful information - I wondered why the reverse of my 1997 Quarter was purple around the eagle. 👍

thats cool, and beautiful

"But I'll leave that up to you." LET'S BE REAL MR. NURD... I WILL MOST LIKELY NEVER IMITATE ANY OF YOUR VIDEOS... but they are orgasmic.

That was pretty cool bro!!!

The fact that people cry so much about AT coins is crazy I say it’s fine as long as you are not selling them as natural. I also think these grading companies should still grade them

Thank you for the reupload

Thanks for being sensitive to the numismatists out here! Great video! Thanks!

Good work.

5:38 ammonia works the best in this case. It complexes the silver sulfide and washes it off. Of course you still lose part of your silver, but it's way better than scripping it off.

This anodization actually works pretty well with bismuth too!

Great video thanks for the education 👍🏼 🇺🇸🇺🇸🇺🇸

It's amazing how a good camera can get a super sharp image for 480p video

Alright lets do this with titanium now :)

RE-Do the Potassium Video :) It was awesome and very detailed

Hey baking soda made with water into a paste works great to clean silver Use warm water and make a soupy paste it works great for non key dates

Liked and subscribed 😎

Fascinating, I wonder if this can be done with any other metals.

Can you refine uranium ore if it is convenient for you?

I loved this video! thanks! also, is the anodized color durable? is there any way to seal it on silver?

What was wrong with the other one?

is there a chemical way to anodise aluminium?

On this example if you only want the tarnishing to occur on one side of the coin is there anything you recommend that can sit in the sulfide solution and protect the coin... Would prefer not to use Vaseline and then use a harsh chemical to take it off. Just looking for recommendations. Thanks. Loving your videos.

Would this work on Copper

Would this be noticeable within the grading companies? Or leaving it in the dirt and sun for months a better way?

Is this how they make the trending rainbow knives?

You can do the same with titanium wire and just water and change voltage

Very cool

It's amazing, thank you! What will happen to silver coins when they are put into sodium sulfide solution without electricity? Are there any color changes? If color also appears, how is this different from the color under power on conditions? We look forward to your reply.

Dude that's so freaking awesome!!!! I see people selling coins way over spot all the time that are toned but how can you tell if it was done naturally or not and what does it matter if you get the same result? I have bought ASE from my lcs for spot that were turning rainbow colors but i always dip them in tarn x I love shiny white silver. Great video

I'd love to see some videos on electropolishing too!

As a jeweler is there a easy way to get an even black that won't rub off, and yes there are chemicals in the industry but getting the same finish ever time is challenging..

I didn't realize you have that much control over the film thickness. Is anodization used to create structured/patterned thin films?

Thanks for the very clear info! I tried this, and what I got was an all-over antique yellowing without any rainbow colors. I had trouble getting my sulfur powder to mix very well since I don't have a magnetic stirrer, and the toning process took longer than yours did. Could not having enough dissolved sulfur be the reason I didn't get any pretty colors?

Excelent video

Do this to your silver playbutton

Супер! Этот метод только для серебра? Медь? Бронза? Никель?

How about thiourea instead of sulfide? Maybe less nasty if it works?

HI. In this video at 3:37 you talk about "dichromate solution". Could you point me to the link of the video where this is mentioned? I am very interested in this solution. Thank you so much for your videos....👍

Hi. How well does this work with pieces that have souldering added on them.

What was fixed if I may ask?

My pale yellowish white solution did work for practicing but I am wondering if solution needs to be orange to work better AND WHY ITS NOT TURNING ORANGE AND STAYING SULFUR COLORED-- do I need to buy the stirrir you have and if I do what’s it called? Took chemistry in college and high school years ago so I forget but I think that may be the key....,

can i get sodium sulphate by electrolizing that solution with an PbO2 anode?

What was the problem ?

Would this work on small glass items that were silver plated? But vase, toothpick holders etc.

hi, id like to tone my glasses frames, can you help me out doing it, im a science student so dont worry about me handling the chemicals

Does this work with bismuth? E.g., after growing a crystal can you add more color?

Good job I want ask you may i do this way for bronze or copper

Good job brother I want ask you brother can i do for bronze or just for silver only

What happened?

Would this work on lead like to artificially tarnish a stained glass windows? I know that there are patina compounds commercially available .

Please do not leave us curious viewers unsatisfied: What was wrong with the video posted a few hours before?

Didn't notice anything wrong in the one you uploaded a couple of hours ago? -Or any difference for that matter :)

I just studied at Hobo coin carving. Is that Buffalo coin really big? custom coins?

Can I do that with any kind of metal?

Will this process work with liver of sulfur?

Does this type of artificial toning damage a coin if not done to the point where silver sulfite is created on the coin and the coin turns black? I had also stored some rare, certified coins near unopened cereal boxes and I noticed that some of the coins were developing tarnish or toning on them so I moved the cereal boxes. Have my coins been harmed by being exposed to the unopened boxes of cereal? I have since moved the cereal boxes. One of the coins has toned a little dark.

I'm guessing this is pretty much the same as using liver of sulphur... Is this method here permanent and hard to rub off?

Tried this with sodium hydroxide only on two different pieces of silver. Had no reaction take place other than a little bit of, I assume, hydrogen gas forming on the cathode. Where did I go wrong?

Can I use this polysulfide to dispose mercury Nitrate? To make mercury sulfide?

Hi- I’m not sure if you’ll read this but if someone could answer me it would be great- it’s actually about the toning coins with anodizing- I am making the solution exactly like you said- HOWEVER I DONT HAVE A STIRRIR LIKE YOU- 1st I tried a mason jar and covered it, it got really hot and never turned orange even shaking it forever - next I did the 1/2 cup water with 2 tablespoons and 1 tablespoon meathod also in glass mason jar- I did a circular motion for about 12 min and NO ORANGE COLOR AGAIN!!!! Why? It was covered so I took the cover off after about 12 minutes thinking that covering it was the problem, stirred a little more but never turns orange- what am I missing? Help please!? Next I’m going to try uncovered with the 1/2 cup and 2Tb&1Tb method in circular tornado motion (I don’t have the magnet yet, maybe that’s the issue? But I’m stirring it similarly) - please help.

Could you UN-tarnish it by reversing the polarity?

Are there other chemicals you can use to do this with?

Where would I get a battery contraption like that? I’m assuming it came from a toy or other electronic device. I’m not much of a tech guy, so I’m hoping someone on here can help me find something suitable.

I shared your vid

Is this normal water or di water also can you do the same thing on gold 18kt

Make a video doing this with gold. Or gold mixed with copper

Would using KOH have the same effect?

Silver sulfide can be removed by thiourea solution.

Could you use potassium sulfate instead of sulfur powder?

Does this work on other metals besides silver ? ie : stainless steel ? mild steel ?

Was the backside of round toned as well?

Will steel work too

What other metals would this work for?

Can this be done with potassium hydroxide and sulfer?

Now I gotta look up "numismatic".

will the toning either natural or artificial get lighter or darker over time? Can the rainbow effect darken or be lost over time like during years or months of storage? I have seen the morgan dollars in PCGS holders on sale- are these colors permanent or is only the natural toning permenant?

Can someone explain to me the part from 05:01 to 05:20 ? Thats is that? So when silver tarnish too much it will create black silver sulfide which will then fall off of silver? So when silver tarnish too much you will lose silver content when this black silver sulfide fall off? If i understand this right, silver sulfide will fall off of the coin surface and it will take some silver with it, can someone explain this chemistry to me?

What about toning copper?

Is the solution safe for storage?

I'd love to know if this could be achieved with chromed metals
