This piece was probably fired in a kiln like the one we have here. The glaze was applied with texture and the top was dipped/painted with a darker glaze. I like the way the colors are placed and how they are all the same basic color but different shades. We could do this in our classroom.
This piece was probably also fired in a kiln. To glaze it, they might have dipped the top and flipped it over so it dripped down the sides. I really like the choice of color and the way it drips down the side. We could probably do this in class.
