A water-resistant porcelain enamel coating and method of making the same is provided. The porcelain enamel coating is prepared using a borosilicate glass frit, and mill additions of silica and a zirconia compound. The mixture is applied to a metal substrate and fired, resulting in a water-resistant coating that resists cracking and crazing. The coating is particularly useful in water heaters. In one embodiment, the coating comprises a fine zirconia compound having a median particle size of less than 10 microns.

An anti-microbial porcelain enamel coating and a method of preparing the coating is provided. The porcelain enamel coating contains an anti-microbial agent having an anti-microbial metal compound such as silver, zinc, or copper disposed on a particulate support. The resulting porcelain enamel coating can be used, for example, as a coating over steel for those appliances and sanitary ware fixtures that could benefit from an increased level of resistance to microbes, mold, bacteria, and fungus.
