markn984 Valued Member United States 120 Posts	Posted 04/12/2012 2:17 pm I noticed this on ebay. http://www.ebay.com/itm/TONED-1999-...ht_591wt_905 It is obviously artificial toning, but I can't, for the life of me, figure out how this toning is achieved. How did someone manage to get all the raised surfaces one color, with a black background? Anyone know? Thanks! Report this Post to the Staff

The whole thing has been crayola'ed, it is just the lighting that makes the fields look completely black. Report this Post to the Staff
Mechman Valued Member United States 275 Posts	Posted 04/12/2012 3:40 pm I Googled this and found some interesting things about nickel. Heat may be a factor too. This guy is a platter. Is there any process that can turn nickel and steel into various colors without paints or coatings? Billy Tucker researcher - Livermore, California +++ The literal answer is "no" because nickel and steel are the color they are, and anything that would change the color of the surface is a coating. But there are conversion coatings that are inorganic and are very thin that you might not really want to exclude, such as black oxide processes for iron and cyanide-based blackening agents for nickel. pic of Ted Mooney Teds signature Ted Mooney, P.E. finishing.com Brick, New Jersey Edited by Mechman 04/12/2012 3:45 pm Report this Post to the Staff
unholyroller Pillar of the Community United States 1903 Posts	Posted 04/12/2012 5:16 pm I used to do some vapor metal coloring to things other than coins....used to use hard wax where I didn't want coloring, then just cleaned it off when I was done. Anywhere the wax was wouldn't colorize Report this Post to the Staff

Biokemist, could you explain a little more on how this process is done. Interesting to me. Thanks Report this Post to the Staff

The type and angle of lighting plays a big role- http://www.coinnews.tv/Secret-is-in...lighting.htm Report this Post to the Staff
