cleaning old muslim coins:

[Peg Leg]

I found out something very interesting yesterday.
I started cleaning some very old Muslim coins.
I used a sonic vibrator, a little water and a spoon of comet.
I put in 12 of these Mid East coins and 1 reale spanish silver coins a few chinese silver coins and turned the vibrator on. I let it run for a couple hours. Guess what EVERY Mid East coin desolved to nothing. The other coins were fine.
I would now say that I think that the Muslim coins were actually made in china and had no silver in them at all.
GOOD

It might be an ultrasonic washer:

What were they made of that caused them to disolve? Were they made of soap or what?

 

[TheDetectorist]

Well, either soap or maybe a coin that was reduced to a corrosion disk in the shape of a coin, so that when "cleaned" it disigrated because there was no true metal left in it.

I have no idea except EVERYTHING was gone. I had a few other REAL silver coins in with these things and even they were damaged nd yes it was a ULTRA SONIC cleaner. Beats 5,000 times a second.
I use it to clean jewelry but with out the COMET .

Peg Leg,
The coins that disolved; were they silver in color before you put them in the ultrasonic cleaner?

YOU ARE NOT GOING TO BELIEVE THIS
My 21 year daughter thought it would be funny if she removed the Islamic coins just to see my reaction. Well she saw my reaction ALL RIGHT . I do not mind a joke but don't mess with my gold or silver items.
I put the coins back into the machine and added some soft scrub liquid.
It is running right now.
They are looking much better NOW that they did not desolve away
Now that I think about it it was

LOL! That's one funny girl! I give her kudos for the prank. And a second kudos for keeping it going for so long.
