Beginning ceramicists learned about carving clay to create interesting tiles. Once the tiles were bisqued, they did a non-glaze surface treatment to them. Students used oil pastels to add color, then covered the entire piece with black tempera paint. To complete the treatment, the students ran the tile under water to wash away the extra tempera. The oil pastels acted as a resist, only allowing to penetrate the clay where the color was not. It gives an interesting look to some wonderfully carved tiles.
