Ceramic is a hard, brittle, heat- and corrosion-resistant material made from nonmetallic minerals, such as clay. Porcelain is a translucent, white form of ceramic used as a coating on many household appliances and features, making the surfaces smoother and easier to clean. Ceramic coating has become popular on metallic surfaces such as iron sole plates and stove tops because it conducts heat and distributes it evenly. It also acts a protective nonstick barrier. With frequent and consistent use of these everyday items, you can scratch the thin layers of ceramic, exposing the underlying metal base. You can easily fill and fix some scratches, thereby saving yourself the expense of replacing the entire appliance.
Things You'll Need

Mix warm water with a few drops of dish soap in a bowl. Dip a cleaning rag into the soapy water and use it to clean all grease, dust and dirt in and around the scratch. Dry the surface completely with the dry portion of the towel or let it air dry.
Rub the abrasive finishing paper over the scratch. This will rough up the smooth ceramic surface, allowing the porcelain layers to adhere better.
Shake the porcelain repair bottle before opening it, allowing all of the mixture to fall from the bottle's cap for cleaner opening. Open the cap carefully and wipe any drips from the bottle rim immediately so it doesn't harden and make the bottle difficult to close later.
Dip the applicator brush tip into the bottle lightly, using only the amount needed to cover the length of the scratch in one thin layer. It is better to cover the scratch in several thin layers than one thick layer.
Brush a thin layer onto the scratch beginning at one end and working the brush all the way to the other end of the scratch in one full stroke. If you are unable to cover the length of the scratch in one stroke, dip the brush in porcelain mixture again and continue covering the scratch from where you stopped.
Wait approximately one hour after applying the first full layer of porcelain before applying a second or consecutive layer. The surface must be completely dry before applying another layer so the porcelain can adhere completely to the surface.
Continue covering the scratch with thin layers until it's form is no longer visible. If the scratch is not deep, you may be able to cover it in just one coat. After you apply the last layer, allow several hours for the surface to dry completely before cleaning and buffing the surface. If desired, sand the surface.
