This allows time for the most recentlyused areas to cool.■ Center the canner on the grate above the burner.■ Do not place canner on 2 surface burners at the same time.■ For more information, contact your local agriculturaldepartment. Companies that manufacture home canningproducts can also offer assistance.CookwareIMPORTANT: Do not leave empty cookware on a hot surfacecooking area, element or surface burner.Ideal cookware should have a flat bottom, straight sides and awell-fitting lid, and the material should be of medium-to-heavythickness.Rough finishes may scratch the cooktop or grates. Aluminum andcopper may be used as a core or base in cookware. However,when used as a base they can leave permanent marks on thecooktop or grates.Cookware material is a factor in how quickly and evenly heat istransferred, which affects cooking results. A nonstick finish hasthe same characteristics as its base material. For example,aluminum cookware with a nonstick finish will take on theproperties of aluminum.Cookware with nonstick surfaces should not be used under thebroiler.Use the following chart as a guide for cookware materialcharacteristics.COOKWARE CHARACTERISTICSAluminum ■ Heats quickly and evenly.■ Suitable for all types of cooking.■ Medium or heavy thickness is best formost cooking tasks.Cast iron ■ Heats slowly and evenly.■ Good for browning and frying.■ Maintains heat for slow cooking.Ceramic orCeramic glass■ Follow manufacturer’s instructions.■ Heats slowly, but unevenly.■ Ideal results on low to medium heatsettings.Copper ■ Heats very quickly and evenly.Earthenware ■ Follow manufacturer’s instructions.■ Use on low heat settings.Porcelainenamel-on-steel or castiron■ See stainless steel or cast iron.Stainless steel ■ Heats quickly, but unevenly.■ A core or base of aluminum or copperon stainless steel provides evenheating.
