Material: Pure copper (1. 2mm thick) with 999 sterling silver coating (33 microns). Hand wash only: Use mild dish soap and warm water. Gently rub with a soft cloth or sponge. Avoid exposure to open flame or extreme heat, which can tarnish and burn the surface. Do not place in the dishwasher: The high pressure and metal racks can damage the coating. Regular polishing is recommended to maintain its natural shine. To remove tarnish: Create a mixture of white vinegar, water, and table salt. Gently rub the affected areas with a microfiber cloth and rinse thoroughly. Copper 80%, Sterling Silver 20%
