'Self Portrait' (Bronze Wolf Skull - Phase 8) by Shane Wilson

The first step in the patination process is to determine the colour and texture of the desired look. A great book, which provides examples of patinas and their recipes, is Patinas for Silicon Bronze by Patrick Kipper.

The patina I have chosen for the wolf skull is called 'Italian Marble'. The effect is a dark jade to emerald green over a black base coat. My intention is to reflect the colour of the jade base while retaining a dark undertone to pick up the dark tips of the musk oxen horns.

The first step to create this patina is to spray the surface with a solution of Birchwood Casey (gun blueing) diluted 50% with distilled water. This is applied with a spray bottle onto the cold bronze surface.

You can see that the colour goes from a light copper to blue-black almost immediately.
