Abstract
In a method of modifying the light reflecting properties of a glass surface by spraying the surface with an etching solution via a bank of spray nozzles while the nozzles and glass surface are relatively moved past one another, conformity of treatment is improved by effecting such relative passage while the nozzles deliver synchronously oscillating divergent spray cones whose relative spatial relationship and/or amplitude of oscillation is such that in any one cycle the impact zones of the spray cones on the glass surface together cover a continuous band-like impact region extending in a direction across such surface transversely of the direction of relative passage.
