Abstract
An apparatus and method for manufacturing a glass article includes a conduit of precious metal or precious metal alloy hat encloses molten glass. The apparatus and method also includes a channel positioned inside or proximate the conduit that flows a defect inhibiting fluid therethrough. The channel includes at least one orifice positioned proximate a free surface of the molten glass from which flows the defect inhibiting fluid.
Claims22
A glass manufacturing apparatus comprising:
- a conduit comprising a precious metal or precious metal alloy and configured to flow molten glass therethrough;
- and
- a channel positioned inside or proximate the conduit and configured to flow a defect inhibiting fluid therethrough, the channel comprising at least one orifice configured to be positioned proximate a free surface of the molten glass to flow the defect inhibiting fluid out of the channel.
A method of manufacturing a glass article comprising;
- transporting molten glass through a conduit comprising a precious metal or precious metal alloy;
- and
- flowing a defect inhibiting fluid out of at least one orifice of a channel positioned inside or proximate the conduit, the at least one orifice positioned proximate a free surface of the molten glass.
