摘要： The present invention provides a composition for use in forming a porcelain enamel coating having a metallic appearance. The composition according to the invention preferably includes a low shear blend of a glass component and metal particles such as aluminum, nickel, copper and stainless steel. The glass component includes at least one glass frit that fuses at a temperature of less than about 600null C. Upon firing at a temperature of from about 535null C. to about 600null C., the composition forms a vitreous porcelain enamel coating that has a metallic appearance, which through the incorporation of various optional pigments and/or mill additions, can range from a bright brushed nickel or stainless steel appearance to a matte dark metallic finish.
