Abstract
A container for baking and browning food when subjected to microwave energy and method of making same. A metal substrate has a ferrite-containing coating with a thickness between about 9.5 mils and about 10.5 mils on one surface and a coating on the other surface suitable for use in a microwave oven. The ferrite-containing coating includes a ferrite and a binder of epoxy resin and polyamide resin and plasticizer resin with the ratio by weight of ferrite to binder maintained between about 1.0 to about 1.8 to 1.0. The coated metal is cold drawn to provide a container suitable for heating various foods to a specified temperature in a short time. The coating is applied to the metal as a paint and then dried. Multiple thin coatings are applied to obtain the final thickness.
