Promoting art is a lifestyle for Zupan, who now lives and creates both pottery and jewelry in Richland. While in Utah he taught art at community education classes in the evenings, during summer school, at workshops with Boy Scouts, Girl Scouts, and 4-H. He conducted university and college classes. And he participated in some unique opportunities to work with ancient pottery techniques.
One of these opportunities was through the Colorado Archeologist Group, National Geographic Magazine, and Mesa Verde National Park, which joined together to replicate Anasazi (Southwest Pueblo People) pottery making and kiln firing. Zupan was one of 20 potters asked to replicate pieces, with each step documented as if were being done 1300 years ago.
Another time he partnered with the Church of Jesus Christ of Latter Day Saints in creating a series of Bible-based films on the New Testament era.
