Abstract
Hot glass is thermally toughened by generating a stream of closely-packed, aerated particles, and projecting that stream towards the glass. A plurality of such streams are projected from an array of nozzles, and the velocity of projection of each stream is sufficient to ensure that the integrity of the stream is preserved in its trajectory towards the glass.
