Every Christmas, I make Christmas ornaments as gifts. In the last couple of years, the ornaments have been etched. The design is transferred to the copper, and then the copper is chemically etched to make the design in copper. Afterwords, the ornament is buffed to a high shine. These ornaments are about 3 inches in diameter. The 2018 ornament is a snowflake.
The 2017 ornament was a Christmas tree. The appearance is somewhat different, as the copper ages to a deeper color over time.
