Abstract: An apparatus for coating glass articles with a chemical compound includes a coating hood section defining an interior chamber having an inlet and an outlet, the outlet being positioned adjacent the glass articles. A blower is positioned in the interior chamber to carry air from the inlet towards the outlet. An injector is configured to deliver the chemical compound into the interior chamber, the injector being positioned in the interior chamber at a location that is downstream of the blower. The injector extends into the interior chamber by a pre-determined distance that is selected to prevent premature vaporization of the chemical compound.
