Abstract: A hood (300) for making a metal oxide coating on glass articles (103) constitutes a tunnel through which the articles (103) pass along a conveyor. Gas carrying the coating chemical is blown/sucked across the conveyor path from blowing and suction channels (301,302) opposed on opposite sides of the conveyor. To reduce the operational temperatures of sidewall surfaces of the hood on the coating region, the sidewalls are made from tapered segments so that only line edges (312) face onto the conveyor path. Reduced temperature of the sidewall surfaces (314) reduces the formation of deposits thereon in operation.
