Close,,,,, but incorrect. Recheck the article

Toning protects the surface of a silver coin......rust completely destroys the metal.....hence the reason that 2000 year old silver roman coins can be pulled out of the ground cleaned up a bit and still show full details
It was also published in the book "Coin Chemistry" written by Weimar W. White.

Fellas, leave the tight pants to the ladies. If I can count the coins in your pockets you better use them to call a tailor. Stay thirsty my friends......

Toning of silver will not IIRC.

edited to add: I'm assuming you are talking about a silver coin and an iron pipe.
I could see film containing silver nitrate turning to a pile of dust.

Yes you are right!! Toning is to silver what rust is to steel......I also have the same book " Coin Chemistry" by Weimar W. White...I suggest you toner lovers read it ,you might change your tone

You are quite right, and Weimar is quite wrong!!

I'd liken the corrosion you see on a silver coin to the bluing process you see on gun steel.
'Blue' steel is a black oxide of iron that does not have the 'mechanically blooming' qualities we associate with rust. It is protective rather than destructive.

Black?
Oxide?
Hmmmmmmmmmmm
I've been told I tolerate fools poorly...that may explain things if I have a problem with you. Current ebay items - Nothing at the moment
<< <i>This thread should be renamed a toast to ricko... cheers
<< <i>reminds me that W. White similarly refered to the formation of a thin silver sulfide layer as "oxidation" >>
I am an educated chemist and what White said is correct. It may seem counterintuitive, but oxygen is not required for oxidation to occur; all you need is an electron acceptor (and sulfur works just fine in that regard). The formation of silver sulfide is an oxidation/reduction reaction. In the reaction, silver (a 0 charge element) ionizes, loses one electron and is oxidized to Ag +1. Sulfur (also a 0 charge element) ionizes, gains two electrons and is reduced to S -2. The balanced equation is 2Ag + S > Ag2S. The layer of ionic compound (Ag2S) that covers the surface of unreacted silver physically separates the two reactants.

I sold this rusty old POS a couple weeks ago...
Happy New Year Everyone

Good answer! The original quote is not a good one. Makes you feel like toning is crap. I like toning. How else are you going to have an old coin thats original? Dip it once a year?
