Embodiment Construction

[0023] In the following detailed description, for purposes of illustration and not limitation, exemplary embodiments illustrating 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 description, that the invention may be practiced in other embodiments than those detailed herein. Additionally, descriptions of well-known devices, methods, and materials may be omitted so as not to obscure the description of the present invention. Finally, wherever applicable, the same reference numerals designate the same elements.

[0024] In the present invention, the terms "upward" and "downward" are relative to the gravitational source (such as the earth), so the upper part of the product is farther away from the gravitational source than the lower part or bottom of the product, and upward is the direction away from the gravitational source , down is th...

Abstract

An apparatus for homogenizing molten glass is disclosed comprising a stir chamber including a rotatable stirrer disposed therein. The apparatus further comprises a catcher coupled to the stirrer shaft, the catcher having a concave, bowl-like shape and adapted to prevent particulate from falling from upper surfaces of the stir chamber into the molten glass. At least a portion of the catcher bottom is in contact with the upper surface of the molten glass, whereas a peripheral edge of the catcher is preferably raised above the upper surface of the molten glass to prevent molten glass from contacting an upper surface of the catcher.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Patent Application Serial No. 12 / 277,676, filed November 25, 2008, entitled "Method of Homogenizing a Glass Melt." technical field [0003] The invention relates to a method for homogenizing glass melts. More specifically, the present invention relates to methods of minimizing inclusions in molten glass materials during agitation. Background technique [0004] Formed glass is often considered a relatively inert material. Indeed, it is for this reason that glass containers are often used as containers in a wide variety of industries. However, in the glassmaking process, the molten glass is transported at very high temperatures (over 1600°C in some cases). At such high temperatures, the molten glass itself can be extremely corrosive, requiring corrosion-resistant piping and containment systems. This corrosion can lead to damage to the container material. Consequently, most m...
