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.

A method of forming a strengthened glass article is provided. The method includes providing a strengthened glass article. The strengthened glass article is in the form of a container including a sidewall having an exterior surface and an interior surface that encloses an interior volume. The sidewall has an exterior strengthened surface layer that includes the exterior surface, an interior strengthened surface layer that includes the interior surface and a central layer between the exterior strengthened surface layer and the interior strengthened surface layer that is under a tensile stress. A laser-induced intended line of separation is formed in the central layer at a predetermined depth between the exterior strengthened surface layer and the interior strengthened surface layer by irradiating the sidewall with a laser without separating the glass article.

Strengthened glass articles with separation features

A molten material apparatus can include a container including a wall at least partially defining a containment area and an opening extending through the wall. The molten material apparatus can include a protective sleeve mounted at least partially within the opening of the wall of the container. A thermocouple can be positioned within an internal bore of the protective sleeve. A method of processing molten material can include inserting a thermocouple into a protective sleeve fabricated from a refractory ceramic material, and measuring a temperature of material within a containment area of a container with the thermocouple.

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.

Ultra-low noble metal doped polarizing glass and process

A passively aligned optical isolator includes laminated layers of material including two polarizing glass layers sandwiching a Faraday rotator layer. Each polarizing glass layer comprises a glass matrix containing elongated metal particles exhibiting a change in polarization axis of less than about 0.0375&#xb0;/m over a distance of at least 8 mm, as measured across a major surface of the layer. The optical isolator has a contrast ratio greater than 40 dB.

Polarizers and isolators and methods of manufacture

Polarizing glass articles, optical isolators including polarizing glass articles, and methods of manufacturing polarizing glass articles and optical isolators are disclosed. The methods manufacture can be used to manufacture isolators exhibiting improved contrast ratio.
