A method for making curved glass sheets ( 6 ) with an applied opaque layer ( 7 ) (e.g., enamel or water-based) wherein the sheet is passed through a tunnel furnace ( 1 ) having a number of gas or infrared ( 2 ) and microwave beam ( 3,4 ) heating sections. At least two microwave beam heating sections ( 3,4 ) are installed in the furnace and in each of them, a microwave beam ( 5 ) with appropriate frequency and power density, is provided to accomplish firing or curing ( 3 ) of the opaque layer ( 7 ) and shaping ( 4 ) of the profile.
