Such a great design. Made from Silver Plate, and does polish up if you desire. It is lined with glass. I have polished a small place on the front as shown. If you want to leave it to re-tarnish, it should not take long. Use this cool trivet for hot pans, glasses with condensation or even to show off something you love on a table. I have shown a Japanese Tea Pot for an example. A beautiful and collectible work of art! Signed on the side edge.....
