Brass Patina

This was a problem to achieve, brass usually get dark brown patina in selenic acid, but hence it is difficult to find I mixed up some solution and i am satisfied with the result.......I find it is important to rub the surface of brass to allow the chemicals to work deeper.It also needs to be heated which make it dangerous to work with liver of sulfur because of the highly toxic fumes!!!!Now all I have to do is to try to remember what was the exact formula for the solution :(
