This is red clay, we added texture with leaves pressing them on the clay slab, then we put the slab in a small dish to give it the curved shape (it’s possible also to dry it with a hairdryer). When it is dry you fire in the kiln and paint the leaf impression with dark brown, then you can sponge it off. The light color is the last color we’ve painted.
The colors are like SLIP COLORED CLAY, but you can also use UNDERGLAZE COLORS. These are all opaque colors, so, you need to glaze it with a transparent glaze.
