    Abstract: A method of forming a porcelain enamel article includes firing a porcelain enamel base over a metal substrate at a first temperature. A porcelain enamel cover coat can be fired over the base at a second temperature that is lower than the first temperature. The fired cover coat forms a preselected background color. A decal applied over the cover coat can be fired at a third temperature that is lower than the second temperature. The decal has a predetermined pattern on a carrier and has at least one open region. The carrier burns off and the predetermined pattern of the decal can form a porcelain enamel image fixed to the cover coat. The porcelain enamel image can have more than one color and the at least one open region can allow the preselected background color of the cover coat to show through and be incorporated into the image to form an identical color match in the image and the cover coat.
