The present disclosure is directed to methods and techniques for gob-pressing a glass part of challenging geometries, such as large surfaces with thin thickness as well as features positioned far from a centroid of the part.

Glass parts and gob-pressing methods for making such

An article includes an optical transforming layer and a guide region positioned inside and adjacent to at least a portion of a perimeter of the optical transforming layer. The guide region comprises an inlet end positioned adjacent to a first surface of the optical transforming layer and an outlet end positioned adjacent a second surface of the optical transforming layer. The guide region propagates light from the inlet end to the outlet end such that the light is directed from the first surface to the second surface. The guide region includes a phase-separated glass comprising a continuous network phase and a discontinuous phase. A relative difference in index of refraction between the continuous network phase and the discontinuous phase is greater than or equal to 0.3%. The discontinuous phase comprises elongated shaped regions aligned along a common axis and having an aspect ratio greater than or equal to 10:1.

A composite has repeating domains of an inorganic glass and a polymer, such that the inorganic glass and the polymer each have a glass transition temperature (T) or softening temperature of less than 450° C., and at least 50% of the inorganic glass domains have a length of less than 30 μm as measured along at least one cross-sectional dimension.

Organic-inorganic composites and methods of manufacturing thereof

A method of melting glass and glass-ceramics that includes the steps: conveying a batch of raw materials into a submerged combustion melting apparatus, the melting apparatus having liquid-cooled walls and a floor; directing a flame into the batch of raw materials and the melted batch with sufficient energy to form the raw materials into the melted batch; and heating a delivery orifice assembly in the floor of the submerged melting apparatus to convey the melted batch through the orifice assembly into a containment vessel. The melted batch has a glass or glass-ceramic composition that is substantially reactive to a refractory material comprising one or more of silica, zirconia, alumina, platinum and platinum alloys.

Systems for producing articles from glass tube include a converter having a base with a plurality of processing stations and a turret moveable relative to the base. The turret indexes a plurality of holders for holding the glass tubes successively through the processing stations. The systems further include a gas flow system or a suction system for producing a flow of gas through the glass tube during one or more heating, forming, separating or piercing operations. The flow of gas through the glass tube produced by the gas flow system or suction system may be sufficient to evacuate or purge volatile constituents of the glass from the glass tube and/or pierce a meniscus formed on the glass tube during separation, thereby reducing the Surface Hydrolytic Response (SHR) of the interior surface of the glass tube and articles made therefrom.

A hollow glass waveguide and related method are provided. The microwave waveguide includes a glass body including a first end, a second end, an outer glass surface extending between the first end and the second end, an inner glass surface defining a hollow channel that extends from the first end to the second end and a glass material between the outer surface and the inner surface. The microwave waveguide includes a layer of metal embedded in the glass body. The layer of metal surrounds the hollow channel when viewed in cross-section and extends between the first end and the second end of the glass body. The layer of metal is electrically conductive and the hollow channel is dimensioned such that microwaves introduced into the hollow channel are conducted along the hollow channel between the first end and the second end.

A laminated or single layer glass cylinder and its method of making are disclosed. The laminated cylinder glass is a precursor component to enable making subsequent drawn tubing having high optical quality. The laminated cylinder glass may comprise a first layer of glass as a clad glass and a second layer of glass as a core glass. The second layer of glass may be bound to the first layer of glass. The second layer may have a higher CTE from about 5&#xd7;10/&#xb0; C. to about 100&#xd7;10/&#xb0; C. than the first layer of glass. The first layer and second layer of glass may have different softening points within about 200&#xb0; C. of each other. In some embodiments, the first layer and second layer of glass may have different softening points from about 50&#xb0; C. to about 200&#xb0; C. of each other.

An apparatus () for forming the outer layers of a glass laminate sheet comprises a reservoir (), individual first () and second () distributors extending below and in fluid communication with the reservoir, and first () and second () slots positioned respectively at the bottom of the first and second distributors. The slots have a length, the distributors have sides and a middle, and the length of the slots on the sides of the distributors is desirably decreased relative to the length of the slots in the middle of the distributors. The apparatus is useful with a trough or isopipe () to provide clad glass streams to contact an overflowing core glass on respective sides of the trough or isopipe.

An apparatus and methods for bending sheet glass are disclosed. The present invention improves on the state-of-the-art by providing apparatus and methods that prevent unwanted distortion of the glass sheet. The apparatus and methods utilize localized heating at the bend to allow for overall glass sheet temperatures to be reduced, along with optional mechanical devices for improved bend quality.

The invention is directed to a silver-containing polarizing boroaluminosilicate glass composition that has been doped with a noble metal selected from the group consisting of Pt, Pd, Os, Ir, Rh and Ru, including mixtures thereof, to nucleate and precipitate silver ions to silver metal without the need for a reducing atmosphere step. The invention is further directed to a method for making the glass composition of the invention. Using the composition and method of the invention, one can prepare a glass having a selected null transmission range.

Process of making a visible polarizing glass

The invention is directed to a method for preparing visible light optical polarizers using a non-halide silver salt and any glass composition that the non-halide silver salts is soluble, provided that the glass composition, including the silver salt, was a halide content that is, on a molar basis, 10% or less than the silver content, on a molar basis, of the glass composition. The silver containing glass is hydrogen reduced prior to stretching to form an optical polarizer. The invention enables one to form a visible light polarizer having a polarizing layer thickness in the range 10-40 &#x3bc;m in which the silver particles have a surround index sufficiently removed from the blue polarizer region to allow good contrast.
