<p>The present invention provides devices for glass melt delivery and methods for using these devices. In these devices, a delivery nozzle (3''') comprising at least one platinum group metal material is directly heated by electricity. To facilitate heating, a cylindrical heating ring (18) is mounted in ceramic base (7'''). The device's construction ensures a regulatable heating of the nozzle and the melted glass flux.</p> |
