Porcelain enamel hobs are created by fusing a glass surface to metal under very high temperatures, according to Michigan State University. These surfaces are durable and resist cracking, but they aren't indestructible. Dropped cups or pans can nick the surface. Boiling heavy pots of water, such as those used for canning, for lengthy periods of time also might cause crazing or cracking of the enamel surface. Crazing occurs when the enamel surface cracks in many tiny fractures.

Fill a sink with warm water and two squirts of dishwashing liquid. Dip a rag or sponge in the sudsy water and wring it out.
Scrub the chipped surface of the stove well, completely removing all grease and grime. The repair glaze won't adhere properly to dirty surfaces, so repeat this process if necessary until the enamel is clean. Air dry for two hours.
Shake or stir the repair glaze to mix it. Apply the repair glaze in a thin coat, using the brush provided. Allow the glaze to dry for 24 hours. Apply several layers of glaze, if necessary, to completely fill the chip, allowing each layer to dry between applications.
Gently sand any rough edges so the glaze is level with the surrounding surface.
