For those of you who don't know, Verdigris is the common name for the green coating or patina formed when certain metals are weathered and exposed to air or seawater over a period of time. You have probably seen the effect before on old copper piping or lawn ornaments. Here's how to copy this effect on your miniatures. You will need a selection of paints similar to this:



Iyanden Darksun will be the basecoat, and Shining Gold and Burnished Gold will be the colors for the metal itself. Hawk Turquoise and Thraka Green will be used to achieve the verdigris effect.
You will also need a model, obviously. I am using this one:



Ignore everything except the standard he is holding. That is what we are going to apply the verdigris effect onto. Whether you prime with white or black does not matter in this case, I just prefer to use white.
The first step is to paint all the areas that you want to be gold with the basecoat, in this case Iyanden Darksun (any brown, ochre, or yellow color will work fine). As always, be sure to water down your paints sufficiently so you don't cover up too much detail.
Next, I'll apply the first gold coat, which in this case is Shining Gold.



Here is where we will be applying the verdigris effect. I mixed equal parts of Hawk Turquoise, Thraka Green wash, and some clean water together, although any combination of blues and greens will work. Just remember to keep it very thin so it flows into the recesses of thei piece. Apply this liberally over the gold areas.



Once this dries, it's time to finish our model. I'm going to drybrush a layer of Burnished Gold over the whole area, and still allow the verdigris to show through in the recesses.



And there you have it! Easy and great-looking verdigris!
