Patina in progress

Here i use natrium sulfid to make the bronze darker. I first polished all the finished statue and then add it, heating the bronze to make the darker effect. I do this in many layers, little by little. After making the patina almost black, i start to polish the sculpture to bring the highlights more visible.

With this one, i first polished and fixed the casting errors, then added natrium sulfid and the nitrid acid mix to bring out the green patina which looks almost like a moss. Classic dark greenish bronze statue patina.
