Ever wonder how new glaze colors are developed, or how two glazes will look when they are mixed together? Testing new glazes is useful to understanding how ceramic materials work. Unlike mixing paints, glazes do not always have reliable results. For instance, if equal parts of red and blue paint are mixed, purple will result. The same is not always true for glazes. Some colorants are stronger than others are and some chemicals will react with others producing an unexpected result or color. Testing glazes is always recommended before using them on your artwork. Using a Triaxial Blend is a good way to quantitatively measure glaze-mixing results. Triaxial Blends are used to test three different ceramic glazes at once using measured percentages of each.
This lesson provides opportunities for students to:
Learn a method for mixing measured quantities of glazes.
Explore the possibilities of creating new glaze colors.
Learn about using percentages in Art.
Develop “left brain” skills using “right brain” activities.
