After using the worst cleaning methods, for example, citric acid, vinegar, etc., the question inevitably arises of how to return the lost panina. The simplest of all imaginable and not so simple methods is sulfur ointment. You can get it at any pharmacy and it is cheap and not dangerous if it comes into contact with your hands. Next, all we need is a pair of cotton swabs and a napkin. The process itself is nothing to describe — rub the coin, rinse it off under hot water, and watch. If the result is not satisfactory — repeat.
In order not to be unfounded, I personally tried this substance. For the experiment, I took two previously killed coins, namely 10 kopecks from 1837 (killed with citric acid) and 2 kopecks from the Thunderstorm of 1812 (kept in vinegar). Frankly speaking, this is a difficult selection for such research. The coins are stained and corroded, but in some places the original black patina has been preserved. Here they are in the photo below.
It was necessary to somehow correct the matter, the only hope was sulfur ointment. Here are the reverses.
I took just a little ointment and began to rub it in. The coins are darkening before our eyes. I didn’t see much point in leaving them with the ointment applied for some time. You can easily raise the relief if you rub it with the same napkin or cloth. For clarity, I’ll demonstrate what I did.
Now you can even look from afar without shuddering. Again, I repeat that the coins were not ideally selected for such an experiment. If you take coins after electrolysis, without stains and potholes, then you will get a result much better than mine.
Watch the video next. The same sulfur ointment, but using an iron.
What do you say? We tried this already?
