<p>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.</p> |
