Abstract
The apparatus (300) for feeding, homogenizing, and conditioning a high viscosity glass melt for manufacturing display glass has a stirring device (110, 406), an upstream connecting part (100, 400) that connects the stirring device (110, 406) to an upstream melting and/or refining unit, and a downstream connecting part (120, 420) that connects the stirring device (110, 406) to a downstream forming or shaping device. Wall material and base material of the first and connecting parts and the stirring device (110, 406) coming in contact with the glass melt are made from a zirconium-dioxide-containing fire-resistant material containing a large amount, preferably more than 85 wt. %, of zirconium dioxide. A method of operating the apparatus to make display glass is also described.
