Embodiment Construction

[0110] In the following detailed description, for purposes of explanation and not limitation, example embodiments disclosing specific details are given in order to provide a thorough understanding of the present invention. However, it will be apparent to those of ordinary skill in the art, having the benefit of this disclosure, that the invention may be practiced in other embodiments that depart from the specific details disclosed herein. In addition, descriptions of well-known devices, methods and materials may be omitted so as not to obscure the description of the present invention. Finally, where applicable, like reference numbers refer to like elements.

[0111] Glass articles are typically made by first melting raw materials and / or cullet in a melting bath in which the raw materials and / or cullet are heated to high temperatures at which the raw materials react to form a fluid glass melt. The glass melt is then subjected to further conditioning such as fining to remove ai...

Abstract

A glass melt handling vessel, such as a glass melting furnace, comprising a side-wall monolithic electrode having a stack of multiple pieces of blocks of electrode material, or a pushable electrode, and a method of making a glass material using such vessel. The pushability and / or the use of stacked monolithic electrode prolong vessel life and improves glass melt quality during life cycle of the vessel.

Description

[0001] Cross References to Related Applications [0002] Pursuant to Title 35, United States Code, Section 119, this application claims the benefit of priority to U.S. Provisional Application Serial No. 61 / 491469, filed May 31, 2011, upon which this application relies and which The US Provisional Application is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to glass melt processing equipment and methods, in particular, the present invention relates to an electrical glass melting furnace using electrodes to melt glass material, and a corresponding melting method.
