Ongoing changes will continue over time with all Nordic Products depending on the local environment. A thin layer of copper sulfide is formed on bronze surfaces. Nordic Green surface finishes can be combined with each other or with other surface finishes to create various visual impacts, e.g. By exposing the copper to ammonia, the fumes from the chemical will react with the surface of the copper creating the green patina layer within a matter of.
