Handmade from creation, molding, to firing. Made using Ryukyu glass. This is a ceramic plate. I carved a turtle, seaweed, a whale, and a starfish, then set Ryukyu glass into the carvings and fired it in a ceramic kiln at 1230 degrees Celsius. The plate is 0.5 centimeters thick. As a ceramic plate, I think it can be used in various ways, such as placing potted plants, placing hot pots, or for decoration. This is a one-of-a-kind item. Thank you for your interest.
