Birch is one of the Texas Two Step Overcoats, and can be layered with Licorice, Coffee Bean, or Brick Redto produce an oil spot effect. It can also be used on its own for a slightly mottled, neutral color. Oil spot glazes at cone 10 provide some of the most striking and unique finishes in ceramics. Now, Coyote Texas Two Step glazes provide the same sought-after effect at cone 6, in a breathtaking variety of color combinations. These food safe glazes work as a two part system, with the top coat pulling away to reveal brilliant spots of the glaze beneath. There are currently three Step One Undercoats and five Step Two Overcoats available. You will need at least one Step One Undercoat and one Step Two Overcoat, used together, to get the oil spot effects.
To use the Texas Two Step glazes, simply apply a Step One Undercoat to bisque ware (two or three coats brushing, one coat dipped) and wait for it to dry completely. Then, cover all or part of the first color with a Step Two Overcoat. When the piece is fired to cone 6 in an electric kiln, the glazes will interact, creating a phenomenal oil spot effect. Varying the thickness of the glazes during application will have a dramatic effect on the finished piece, as the thicker the glazes get, the larger the spots they create will be. We found the optimum thickness to be two coats of the Step One Undercoat and three coats of Step Two Overcoat, but you may prefer thicker or thinner applications for different effects. Try experimenting!
