^^^ Thank You Spock. I wasn't sure, but the Canadian mint, they are the masters of this technology that's for sure...

 

Ben dont you know that's Sea water :whistle:

 

I don't know Steve, my head is always bumped when I try to jump in. LOL...

 

Blues and greens are easyt achive on nickels. All you need is a gas stove......... OH! I know how to quickly tone silver too. Put it in a bit of acitone, and light it on fire. That makes really nice rainbows.....

 

woah a $150 premium on a bluish coin..??? they have to be kidding!

 

cant you rub that toning off though?
ive tried toning pennies, and it seems like you can rub some of it off.

 

So what exactly does "plasma effect" mean? According to Wikipedia it is an optical illusion created by digital manipulation of images (http://en.wikipedia.org/wiki/Plasma_effect).

According to an article on CanadaDigital, the color of the new Canadian coins is

"achieved through a unique, leading edge plasma effect. The RCM is the first Mint in the world to produce this jewel-like finish on a coin, by virtue of a proprietary coating which can produce different colors by varying its thickness. The blue effect was chosen to evoke the cold climate of both poles. "

I still don't understand what this has to do with plasma, the plasma effect or how the effect is achieved, if indeed it has been made public.

Anyone here know?

 

Can you say anodized? I've seen a lot of aluminum Mardi Gras tokens with this blue color. Anodizing is an electrically deposited oxide coating (there's your plasma) and the color is then normally achieved by dying.

 

Just a thought, we have plasma cutters at work. Plasma cuts and can be focused by magnetic fields. They are probably cuting the surface to a precise depth and the only light reflected is blue because of the wavelenth and the depth and angle of the tiny cuts. Deeper cuts may produce red and shallower cuts may prouduce violet. Just a guess.
