"For each etched piece, sturdy, half hard copper (or brass) is sourced and etched with a multi-step process that requires several hours depending on size. Your art piece will be both enduring and beautiful. Etched copper or brass art featuring Queen Anne's Lace blooming. Etched copper or brass flower and leaf detail. Metal colored with translucent inks and patinas to enhance the beauty of the etch. Finished with a clear sealer which further enhances the etch and ensures it remains tarnish free.
