To know the fascinating story of the horse named Eclipse,
refer to Post #152, February 4, 2012.
The patina for Eclipse was achieved using the following method: The cold bronze was doused with liver of sulfur (below) and then rinsed. At right, the bronze was heated with a propane torch, then cupric and ferric nitrate was alternately sizzled and stippled on the hot bronze.
This application is a traditional, old world patination.
Bronze is over 95% copper and typically, depending on atmospheric conditions, location and other issues, turns
blue green without chemical inducement. We've all found
an old copper penny with a natural blue green patina.
