A method of producing a glass product requiring minimum fining wherein finely pulverized glass batch material is heated very rapidly in suspension in a hot gas stream to at least about its melting temperature in a heating chamber and directing it through a nozzle to impact on an impact surface in a separation chamber where the glass batch material is separated from the hot gas stream by adhering to the impact surface. Upon impact, the particles and/or molten material form a continuously flowing layer which flows over a flow surface as a molten layer into a pool of molten glass product in a collection zone. The melt flow over the flow surface is controlled to effect the immigration of gas therein to and then leave the exposed surface of the melt flow and simultaneously effect at least substantial reaction of the glass batch material before it reaches the collection zone. |
