Methods of making glass include the steps of providing a glass melt in a first melting furnace and flowing the glass melt through a connecting tube from the first melting furnace to a second melting furnace. The methods further include the steps of heating the glass melt within a first area of the connecting tube with a first heating device and heating the glass melt within a second area of the connecting tube with a second heating device. Apparatus for making glass are also provided with a first melting furnace, a second melting furnace, and a connecting tube connecting the first and second melting furnaces. Example apparatus include a first heating device configured to heat the glass melt within the first area of the connecting tube and a second heating device configured to heat the glass melt within the second area of the connecting tube.

Apparatus for making glass and methods

A system and method are described herein that control the environment (e.g., oxygen, hydrogen, humidity, temperature, gas flow rate, pressure) around one or more vessels in a glass manufacturing system. In the preferred embodiment, the system includes a closed-loop control system and a capsule that are used to control the level of hydrogen around the exterior (non glass contact surface) of the vessel(s) so as to suppress the formation of gaseous inclusions and surface blisters in glass sheets. In addition, the closed-loop control system and capsule can be used to help cool molten glass while the molten glass travels from one vessel to another vessel in the glass manufacturing system. Moreover, the closed-loop control system and capsule can be used to maintain an atmosphere with minimal oxygen around the vessel(s) so as to reduce the oxidation of precious metals on the vessel(s).

System and method for controlling the environmental around one or more vessels in a glass manufacturing system

A method of forming a glass melt including heating a glass feed material in a first melting furnace to form a glass melt, flowing the glass melt into a second melting furnace through a refractory metal connecting tube, and further heating the glass melt in the second melting furnace. The refractory metal connecting tube is heated to prevent the molten glass from excessive cooling, and to ensure that the glass melt entering the second melting furnace is equal to or greater than the temperature of the glass melt in the second melting furnace. An apparatus for performing the method is also disclosed.

Method of forming a glass melt

The level of precious-metal inclusions in glass products, e.g., glass substrates for liquid crystal displays, is reduced by stirring molten glass in a stir chamber () under conditions such that the magnitude of the shear stress &#x3c4; on the chamber's wall () and on the surfaces of the stirrer () is reduced while at the same time, the Q&#x2022;E product for the system is kept high, where Q is the flow of glass through the stirring system and E is the system's stirring effectiveness.

Rope cleat

A glass melting furnace is disclosed having a refractory melting vessel provided with a protective liner formed of an oxidizable refractory metal such as molybdenum, wherein the liner projects upwardly within a molten bath contained within the vessel and through its fusion line into a batch blanket retained thereabove which is low in carbonates. The upper end of the liner is provided with a seal to prevent the flow of batch material between the liner and the refractory vessel and thereby prevent contamination of material behind the liner and reduce corrosion of the refractory vessel.

Filter case rotatably carries two filter retainers each with a linearly polarized filter, each at the same angular position. A perforated belt engages around the sprocket teeth on the filter retainers so that the two filters are rotated together. Filter case is removably attached to the camera body.
