I think you should reconsider sticking around. We are here to help and educate. When it comes to conserving and cleaning ancient coins and artifacts using electrolysis is not and approved method and never used by conservators. The use of distilled water and olive oil are among the few methods that are used and produce good results. Yes, the process takes a while but the results do not damage the coin. Over my years of collecting I have cleaned thousands of coins and have use only three methods, distilled water, olive oil, or ultrasound. I have also seen many coins that have been zapped and it's pretty easy to tell that's how they were cleaned.

Please still around, I sure you will be able to get a lot of knowledge and enjoy collecting as much as we do.

It may well prove to be an education to us all, if you could
post some pictures of an example of best condition coin you have treated with electrolysis.

Also, it may well prove to be worth treating a modern low numismatic value bronze coin with electrolysis, that still has mint luster, and to consider the results.

If it turns out OK, post some some pictures.

I have been collecting for many decades, and I still need to be educated.

@gtkwml:
I have learned something about electrolysis cleaning.

I'm in my 5th year in the hobby. 2 years ago I got into a private argument with a very prominent person in the hobby over sharing information regarding the detection of fakes. Since I was new I was always asking about specific detection methods, and his opinion was that the only rule a newbie needed to know was to buy from a trusted buyer. It escalated and I ended up with some pretty hurt feelings.

I've been on the internet since when it was known as USENET and BITNET in the mid-1980s. It's all too easy to get offended or say things you wouldn't say to someone face-to-face. You've got to keep that in mind and most importantly...

Cut the other party some slack.

Try to assume the best instead of the worst. I read the thread you're referring to and I didn't see anything offensive in it. But if you need to chill then do so.

I would recommend that you don't however because this hobby is incredibly small with some incredibly knowledgeable people in it. I've found that it's worthwhile to put up with some BS or offensiveness because the level of expertise on forums like this is pretty high.

Im new here too and not familiar with your posts but reading this thread has been educational, which is what I'm most interested in.

Ive always said that there is nothing like household vinegar and baking soda that doesn't work wonders on anything>>>LOL

My intent was not to make an ad hominem attack, but to criticize the very idea of stripping a bronze coin coin quite literally, down to the bone.
As a general rule I collect (and often sell) bronze coins. Sometimes they need a bit of "conservation" and I have used a variety of household chemicals (even Liquid Plumber !).
But one thing I will never intentionally do is strip a coin down to bare bronze.
Unless you plan on spray painting it with Rustoleum (or from a numismatic perspective) what is the point ?
A barely recognizable LRB is worth more than that.
When I purchase larger lots of bronzes I have sometimes found some of these.
I lump them together in small lots and dump them for what amounts to pennies apiece. !

I read most of the Baylor University paper above.
What struck me most was a comment about a precleaning procedure to remove green "cupric carbonates".
The author discounts the method because
"However, this process took up to twenty hours (or longer), depending on the amount of corrosion"

An object has been buried in the ground for two thousand years and soaking it for 20 hours to improve it is considered a big drawback when conserving it ?
Even minor touch up cleaning can take days if not weeks !
A major job will often take 6 months to a year.
Don't get me wrong .......
I am not some kind of idealistic purist either.
I have done some cleaning and done some 'fixing' by applying things like "liver of sulphur" or as mentioned above dropping in a solution of Drano.
But as I also stated
I see no point in stripping a surface down to the bare bone.
Especially when the result is somewhat akin to using sulphuric acid on it
I don't see any real improvements
I see only destruction of part of its history
The "patina" often preserves many of the details on a coin. Removal can often erase too much and leave a corroded looking moonscape.

My only other interest is .......
What on earth do you do with what must amount to thousands of these coins ?
I imagine a kilo would be close to that and you say better than 90% get this treatment.
Is this a 'commercial' venture that requires economy ?

BTW
I shall hitherto refrain from comment on all threads dealing with this process

I wouldnt mind hearing about the actual process of electrolysis. No condoning or criticizing it., just normal, learning value curiosity.

In reply to rvfvs - a kilo usually has 350 to 400 coins. Because a large lot may have come from the same hole, there will be MANY the same. I put. The slugs and unidentifiable in a box, keep the best copy for myself, and pass on many to friends, students, and family, who think it's cool to hold coins that once may have been held by Romans.

Further note- skill holds far less than a thousand coins, since you are also buying a lot of Balkan dirt! :-)
Have never tried selling any, but don't rule it out in the future, but I have no interest in making a profit. I also buy vinyl rock albums at yard sales -- and clean them -- then sell them, but I always lose a little money. I just enjoy it and keep a few for myself.

Correcting above: my software was kind enough to change "kilo" to "skill" and I didn't catch it.

I am new to collecting ancient coins... about 7 months.
I have found that across the few forums that I have visited 95% of the people are great (even better than great) and 5% are tired of answering the same questions and just don't have time or patience for newbies anymore. They have been at this for decades. They have their ways and that's it. I get it.. I respect it and I just roll with it.
Others just have a lot of disposable income and have no interest in the bottom feeding coins that I can afford.. that is fine with me. I enjoy looking at and learning from their coins.

I have cleaned a few lots and I have half a dozen or so slugs that no amount of distilled water or olive oil soaking will get anything out of. I know it... nothing anyone will say will change that fact.

If you have a method that has a chance of success I would probably give it a try on these slugs (maybe).
Perhaps if you photographed a coin before trying, logged pictures throughout the process, documented the method
and showed the finished coin it would help some people out? - including me..

I hope you stay. I keep an open mind and I am sure you can teach us all something.
As with all information it is up to each individual to decide how, or if, they want to use it.

Don't let 'em get you down. You have as much of a right to collect coins, experiment on cleaning methods and post about it as anyone here.

I look forward to your next post on this or any subject.

Cheers!

Claudius - I'll be posting, probably Wednesday, a bit of information on the bad points and good points of zapping. Including recommendations for the best and safest way to do it.
