Abstract
The subject of the invention is a process for depositing, especially continuously, on a glass ribbon (10) of a float line, a reflective layer (3) based on a metal whose melting point is less than or equal to the temperature at which the glass ribbon acquires dimensional stability. The deposition is carried out in a controlled atmosphere, this being inert or reducing, when the glass ribbon (10) has already acquired its dimensional stability, by bringing the surface of the said ribbon into contact with the metal (22) in pulverulent form or in molten form, the temperature of the ribbon during contacting being chosen so that the powder melts and coalesces, or so that the molten metal forms a sheet, at the surface of the ribbon, leaving a solid continuous layer when the temperature of the ribbon is at a temperature of less than or equal to the melting point of the metal.
