Abstract
A hot vitreous substrate 1 travels on a conveyor 2 through a coating station 5 where a metal compound is formed in situ on a face of the substrate 1 by pyrolytic decomposition of coating material 9 sprayed towards the substrate from a spray head 6 which repeatedly traverses the substrate path. Radiant heating means 11 located on the side of the substrate 1 being coated directs radiant heat towards the transverse region swept by the zone of impingement 10 of the coating precursor material 9 on the substrate 1.
