Could you give nichrome a try? I remember seing a site that used it, and it seemed to work...
Seems a heck of a lot easier to buy a few ft^2 of nichrome mesh from McMaster (I need to make an order in the somewhat near future for my laser diodes) than to silver plate copper then platinum plate it...

Silver plating could be fun though... you could try the method described in the patent I posted above. See page 5 Example #1. You've got the silver chloride already.

Eric is right, Iron can be a really bad surface by itself.
Most plating generally follows the pattern: Copper, Nickel, and then Chrome or whatever.
However, to flame plate with platinum deposits is easy. Dip, flame, and repeat as needed.
Cheers,
I like this idea of flame plating...Could you elaborate on it some more?How might I go about flame plating something with some platinic acid? Thanks! Matt

"Dissolve Chloroplatinic acid in 50/50 Et2O/EtOH.Dip the Pyrex in the solution and flame in a bunsen flame.Platinum will be deposited as a mirror finish." (Penn ???)
"The original formula was 0.2 gm of the acid in 5ml each of ETOH AND Et2O.Add 4-5 drops of turpentine.Dip and flame.The book I got this from was published in 1960 and so may refer to vegetable turpentine.I have used it successfuly without turps but the solvent evaporates very quickly.I assume the turps will slow this down.You can dip and flame several times to build a thicker Pt layer."
