This glaze produces a base of black that turns to a deep, variegated cobalt blue where thick. Like others in Coyote's Mottled Series, Mottled Blue is designed to produce beautiful finishes with ease. Simple to apply and suitable for all types of ware, these colors are stunning on their own or when combined with other glazes. May appear thick in the jar, and should be applied thickly.
