Abstract
A method of making colored glass in a float glass process includes the steps of: melting glass batch materials in a furnace to form a glass melt; transporting the glass melt into a float glass chamber having a flame spray device, the glass melt forming a float glass ribbon; supplying at least one coating material to the flame spray device to form a spray having coating particles; and directing the spray onto the float glass ribbon to diffuse the particles into the surface of the float glass ribbon to form a glass sheet of a desired color.
