I created these cute little ID stone after going to the National Art Association Conference last year in Minneapolis. Each class that I work with has a 'teacher code'. They place the teacher code on the back of their art but I often don't place it on their pottery. As you can see below I just set the clay stone in with the group of pottery that it represents. It helps me when I take the art out of the kiln to know what group to return them to.
