When copper is used as a decorative item its covered in lacquer?

When copper is used as a decorative item, it is often coated with lacquer to prevent tarnishing and oxidation, which can dull its appearance over time. The lacquer creates a protective barrier that helps maintain the copper's shine and color, preserving its aesthetic appeal. Additionally, this coating makes the item easier to clean and maintain. However, over time, the lacquer may wear off and may need to be reapplied to ensure continued protection.
