Here's what the Fifth Graders' finished milagros look like! After bisque-firing the clay, fifth graders painted the milagros black with acrylic paint. I then added a metallic finish to each piece (the metallic finish is labeled toxic, so I put it on instead of the students). Last, I seal each piece with a clear coat of gel medium. The metallic finish really makes the clay look like metal. The black paint creates a contrast that shows off each student's texture and pattern work.
