I've used the peroxide method for years. Bill uses 12% strength, but you can buy a weaker mix, I use 3%. That means the reaction isn't as fast and you have a bit of time to watch the progress and judge when you're happy it's done. Some stamps take a little longer than others. As Bill noted, this is only for the Line Engraved stamps.
Question: Does the reaction automatically stop when the true color of the stamp is reached ? From Bill Barrell's explanation I take it that is not the case ... if that is true, then how do you determine when the stamp has reached the correct color ? It looks to me that this would be purely subjective, no ? If I wait a bit longer I get a lighter stamp, if I wash the stamp sooner I get a darker stamp. But then ... would this not be (almost) purely for aesthetics and not a objective repair of the stamp ?
@@michaelpurm2779 no the reaction doesn't stop, although it slows down as the impurity is reacted away. It's one reason I use a weaker solution. When you collect enough of these stamps you recognise the colour range. If you leave it long enough it risks damaging the fibres. The target is the surface reactants that over 150+ years have left a dark appearance. Hence painting it on top works. You'll notice that Bill said 30s in the peroxide....that's all it needs for the stronger solution. A weaker solution allows you to monitor progress and remove when ready.....still not very long. You find that stamps, especially the later reds (SG40 and plates) and the blues of the same period are the worst affected, largely due to the materials in the ink. You can find some crazy dark examples that the less well educated describe as rare shades when they really aren't. Ultimately, it's a perfectly ok thing to do as its just getting rid of the gunk. It's not repairing the stamp in any way.
Hi Scott. You know me, but I try to stay anonymous on here! The main problem is on 2d blues. I start off with warm water (the reaction is quicker when warm) only. I then add 8 vols hydrogen peroxide drop by drop and swirl gently. Once the discoloration is removed and the true colour restored, I quickly pour out the fluid and add distilled water to stop the reaction. I've restored some lovely examples that way, including a beautiful strip of 3 SG23as which I got for £25 in horribly discoloured condition and restored to pristine glory.
Loved the forensic work. Putting a row of four Penny Blacks into water was scary enough, then putting them into a bath of Hydrogen Peroxide was crazy, loved the result. Great video Graham.
Very hitchcockian. Starts with an earthquake an rises... First: "Why is he soaking cover with Penny Black??? Somebody stop him!! AHH... OK... Makes sense.... " But it wasn't much easier later on... 😁
Excellent video, and great information from a line engrave stamp expert. Be very very careful with the use of Hydrogen Peroxide. on postage stamps. I have read about some concerns regarding the long terms effect on the strength of the paper. So be mindful of Bill's advice to limit the exposure to 30 seconds or less. And be sure of the inks on the stamps you are cleaning! There is also a viewpoint that the discolouration or sulphurization of he stamp reflects part of it's 182 year journey. Our role as collectors is to be careful custodians of the material for the relatively brief period that we own them!
Thank you Paul. And yes I think that viewpoint is valid for discussion. I can totally understand both sides of the debate, perhaps something I can explore in the future 🤔
Very informative, thanks for sharing ! I never treated my classic old stamps with hydrogen peroxide because I see that darkening as a part of their history. But from the dealer´s view, it´s just another cup of tea...😉 Greets from GER, U.
Thank you. Yes it’s totally a valid point for debate, do you keep the history of its exposure in the last 182 years, or do you try to keep it as it was issued back in 1840… it’s an interesting discussion. Thanks for watching!!
A superb vignette. I admit to being very apprehensive watching Mr. Barrell subject Penny Blacks, 182 years old, to hydrogen peroxide, but he is obviously a real pro.
You know, seeing someone soaking penny blacks off a cover (genuine or not) is something i have seen for the first time today... To think that back in the 1840s and 1850s Victorians were doing the same to their own everyday mail!
Same, my first time seeing such a thing as well. Funny to think that maybe someone in the future would be upset with me throwing away an envelope I get in the mail today with a 2022 stamp on it, but that could be the case as I would prob have done that in 1840.
It was really a great episode, Graham! When bill got the Hydrozen Peroxide, my heartbeat gone up 😂 But I'm mostly amazed just how he predicted that the maltese cross was red, not brown. However, a great episode, enjoyed a lot 😄
Who would have thought a video on stamps would have my heart racing from nerves. All of the things he did to those penny blacks! Obviously though, an experienced professional. I learned a lot from this today!
I am visiting the UK right now and wished I’d have been able to visit the show. I’ve done business as a client (in Australia) with Bill and his staff and its good to actually see him in the flesh. As to other matters: I purchased a embossed issue of 1848-55 on cover, and like the wrapper in the video I think mine (and others have told me so) is not tied and contrived - original stamps and original cover later combined. I have kept this item as a warning to myself.
Thank you for sharing, Peter. I think this is a lesson for all of us, as these contrived items seem to be a lot more common than we would like. Bill and his team are awesome, it was a terrific experience to see him explore this wrapper. Thanks for watching!
Incredibly interesting and informative! Witnessing the detective work of an expert philatelist was so eye opening and educational. Thanks Bill and Graham.
Hi Graham, I was very sorry to have missed you at Stampex 2022, but my ticket was for the Thursday (September 29). I did ask at the reception and they told me that you were due on the Friday and the Saturday. A great disappointment but couldn't be helped. Hope you enjoyed your visit as much as I did this time. There's always next year !! Hahaha ! Best wishes to yourself and Laura.
Many thanks for these explanations. I had heard of this method but I did not know the technique. Always so instructive, congratulations for your work. I can't wait to see the next video which will undoubtedly be the continuation of the visit!
You are very welcome! My next vid is probably season episode of Exploring Stamps (which is almost fully edited) and then I’ll post another about Stampex, I have A Lot of footage to edit 😊. Thanks for watching!!!
You are very welcome Philip, I hadn’t really paid attention to the idea of Hydrogen Peroxide, but after this I now need to do some reading up on it. Thanks for watching 😊
I am not a chemist, but, I have serious concerns about this demonstration. I have no doubt that hydrogen peroxide removes sulphurisation, but it is also known to be a strong bleaching agent, and it seems to me that some of the effect that we are seeing could be due to bleaching and not just from the sulphurisation being removed. Bill himself confirms the bleaching ability of HP when at 10:15 he makes mention of someone forgetting a few penny blacks in hydrogen peroxide overnight only to find them blank the next morning. Of course, overnight is a lot longer than 30 seconds, but it does show that bleaching will occur, we just do not know how much occurs in 30 seconds. Bill then turns his attention to four penny reds, of which the left-most one is much more sulphurised than the others. After treating it with HP it appears that he has removed the sulphurisation. However, the stamp is now a completely different colour to the others, even in comparison to the least sulpherised example. More significantly, however, the few seconds of exposure to the HP has considerably reduced the intensity of the black cancel illustrating just how powerful a bleaching agent HP is. As for the black Maltese Crosses on the strip of penny blacks supposedly having originally been red, I believe that he is mistaken. Black iron gall ink, which was in widespread use at the time, is known to oxidise and slowly turn brown due to exposure to oxygen i.e it rusts. hydrogen peroxide on the other hand is a very strong oxidising agent and will rust iron in minutes, and that is the effect being demonstrated here, which is simply the hydrogen peroxide oxidising the black ink and turning it brown. Clive
Totally valid comments and observations. Perhaps this is something that we can explore further and do some experiments in a future video, I have other questions as well. Thanks so much for sharing your thoughts..
I see his point, but I have to admit I cringed at watching him soak that wrapper. Personally I'd have left it as is and make a note on my album page. But that's just me.
As he drops the cover in the water, at the lower left on the envelope you can see in manuscript "free". So the cover never had stamps on it in the first place, as Bill explains for other reasons. Also if a cover had 4 stamps on it, you would see more evidence that it carried more than just a sheet of paper. Great video -- we linked to it from StampAuctionNetwork today.
Yes! That’s another good point, I didn’t get Bill pointing it out on camera but you are absolutely correct. Thank you so much for sharing the video 🙏 😊
It was a treat! Bill was very generous in sharing his time with me and allowing all the cameras, it was really cool seeing him in action. Thanks for watching, Mark 😊
What a great video. Several lessons in one, fascinating, thanks for sharing but I don't think I'll be doing that with any of my penny blacks! Far too scary..
Interesting video. The problem with using invasive techniques as shown here is that you need to understand why you are using them and the potential intended and unintended consequences. A conservator is unlikely to use the HP that Bill uses. Rather a ACS reagent grade 30% would be used diluted with deionised alkalised water to about 5% and reagent like magnesium bicarbonate or TAED added to reduce the acidity to approx. 8ph. What you are trying to do use the 'bleach' to remove contaminates without damaging the paper or leave lasting damage. HP over time and exposed to light can eventually result in a darkening of the colour or colour reversion. So, while the video is interesting and instructive it demonstrates the pitfalls of using invasive techniques.
besides the interesting peroxide information, I still have a question about just taking of stamps from enveloppes..... Is it better to use demin-water (demineralised) = osmose water ? In belgium we have a lot of calcium in our tapwater...
As a philatelist and professional chemist - I was shouting 'put the cap back on the bottle of hydrogen peroxide!'. By all means use chemical methods, but keep your work area clear and clean, wear latex gloves, eye protection, and be ready for spills and unexpected cross-contamination affecting other areas and valuable items.
Now I see why he had no problem with the other guy trying to boost his profits, he was about to show how to change the stamp to increase value, love it 😀 😂 Never heard of bleaching them before
I watched a few videos and I have a few stamps that I would like to sell please send me a copy of a book or information we’re I can find out the value of them thanks
Excellent video and explanation of the use of peroxide to reverse sulphuretting. Should only be done by an experienced hand though, which is what happened here. Thanks for the post.
You are very welcome Glenn, I might try experiment on LATE Penny reds where there are known to be issues, I think I’ll keep the chemicals away from my Penny Blacks 😅. Thanks for watching!
fascinating episode, @ 12:19 i have to admit i prefer the before shot as it gives the stamp more contrast. After giving it some thought though I have to be honest I'm not convinced that the H2O2 isn't simply bleaching the stamp / cancellation as opposed to removing oxidation. If you bleach black ink you get brown ink. Furthe, before and after photos prove little unless the before picture was taken (ahem, in color) some 180 years ago..
Graham did you receive my postcard yet. I have a question ,i will print my own pages using ALBUMEASY. I asked PALO if they supply pages without the borders, they don't unfortunately. The next thing is to obtain paper and cut to size of 297 x 310mm [unless there is on the market this size]. looking forward what you got in your stamp journey here. Best regards
By the way: I am collecting in Germany, the classics, obviously, like post-1945. And yes, we have a massive problem with forgery too, e.g. with the Posthorn series....🙄
The worlds most expensive stamp, the Swedish 3 skilling is a fake, were the color has been altered. But nobody cares any longer. It's always the last sale that is more important than the truth.
Could he also use the more hightech forensic philately methods like the spectrometer VSC6000 , I think it could provide even more information about the history of the stamps and cover.
As a postal history seller I think soaking the penny blacks off the original cover is something you should never do. Its always better to see where the stamps came from and were sent to with the destination & postmarks intact on the original cover. What a shame to ruin that cover.
Thanks for commenting Duncan, but if you watch the video, you will see that it is not the original cover and this is why the Penny blacks were soaked off of it.
Yes great video Graham, all stamp collectors should watch this, Bill explained all in his usual engaging manner, look forward to seeing you both again soon

There are probably quite a few of these 'forgery' covers out there, it seems like a simple thing to create :(

Can be done to a mint stamp but brush lightly. Must keep the back dry. A ticklish operation not for the faint hearted!
That was really neat!
Bill was so cool to talk to, he did a great job walking us through the process 😊
Another excellent video. It was great to see you at Stampex last week.
Thank you 😊 I hope you enjoyed Stampex!!
Great video! Loved watching the process and learning from an expert. Keep up the great work! Wisconsin, USA.
Could he also use the more hightech forensic philately methods like the spectrometer VSC6000 , I think it could provide even more information about the history of the stamps and cover.
Who’s Phil Ately?
Only the coolest person out there 😎
Very interesting! These stamps are nearing 200 years old now - no wonder why the experienced UK dealers are so adept at stuff like this.
I have to admit that I cringed when I first saw the topic, but it turned out to make perfect sense and to be very interesting. Thanks Graham!
Boa noite tenho várias stamp para negociar.
Hi we met at Stampex. Really nice show and nice video.
Thank you! It was nice meeting you. Thank you for watching and supporting the channel!
Wow!! The short version brought me here and I am glad it did!!
This was a terrifying video ... and a revelation at the same time!😳
Nice. I use this technique on the orange USA stamps turned brown. Works wonders
Oh great to hear! I need to look more into the process and perhaps discuss it in a future video. Thanks Erik!
Yes, me too. Orange 🍊 stamps are the worst
excellent episode

Cúllar Vega.
That was teaching everyone skills of interest
I agree, interesting for all philatelists, Bill gave us a great set of lessons
That is amazing!
It really was, I was impressed with how Bill explored the cover and stamps. Thanks Karen 😊
I usually call this "inaccurate"
I usually call this a “bot”
Is bot short for something?
That was really cool!
It was! Bill was really generous to let me film him. Thanks Todd!
@@ExploringStamps The though of putting peroxide on a penny black is terrifying!
Awesome :-)
Thank you 😊
That was exiting to watch great show.
Thank you Iwan, glad you enjoyed it 😊
As a postal history seller I think soaking the penny blacks off the original cover is something you should never do. Its always better to see where the stamps came from and were sent to with the destination & postmarks intact on the original cover. What a shame to ruin that cover.
Thanks for commenting Duncan, but if you watch the video, you will see that it is not the original cover and this is why the Penny blacks were soaked off of it.
it was not the original cover, so he can do this
You missed the point of the video Duncan
Yes great video Graham, all stamp collectors should watch this, Bill explained all in his usual engaging manner, look forward to seeing you both again soon
