I work with metal clay and use it to frame the miniature It's 40 years that I didn't paint on enamel, I must learn patience and paint more and thinner layers painted on blythe white opal (bought in 1977) with Schauer paints and an old painting medium I bought in 1974 that smells like terpentine.....I tried lavenderoil and sandal nut didn't like it . I made the frames with bronze clay . The round enamel piece is 35mm Diameter , the square is 35x35mm
