The Bulgarian born American artist Tsvetana Yvanova sculpted this life size clay bust of President Barack Obama. While this video is not a technical how to video of her entire process, it does show some of the final details being added. The bust was made with soft density non-sulphur formula Chavant oil clay. It is very smooth, can be plastered and carved, and when completed can stay as long as needed without drying. A final protective seal of Rustoleum oil was spray coated over the entire piece. The sculpture took about 20-25 days, a few hours a day, over the course of 5 weeks to complete.
