I have my students use acrylic paint to add color and design to their clay projects. I don't think they could stand it if they had to wait even longer to get their treasures back because they were being glazed and fired again. And with acrylic, there is an infinite array of colors they can use, compared to what they would be able to choose from with glaze.
