An apparatus and process for making glass and glass gobs on demand. A sheet of molten glass is provided in a staging section. The sheet of molten glass is held within the staging section when there is no demand for glass articles. When there is a demand for production of glass articles, a portion of the sheet of molten glass is flowed into a gob forming section.

The present invention relates to a method of fabricating an improved lithium silicate glass ceramic and to that material for the manufacture of blocks for dental appliances using a CAD/CAM process and hot pressing system. The lithium silicate material has a chemical composition that is different from those reported in the prior art with 1 to 10% of germanium dioxide in final composition. The softening points are close to the crystallization final temperature of 800 C. indicating that the samples will support the temperature process without shape deformation.

Processes and systems for producing molten glass using submerged combustion melters, including densifying an initial composition comprising vitrifiable particulate solids and interstitial gas to form a densified composition comprising the solids by removing a portion of the interstitial gas from the composition. The initial composition is passed from an initial environment having a first pressure through a second environment having a second pressure higher than the first pressure to form a composition being densified. Any fugitive particulate solids escaping from the composition being densified are captured and recombined with the composition being densified to form the densified composition. The densified composition is fed into a feed inlet of a turbulent melting zone of a melter vessel and converted into turbulent molten material using at least one submerged combustion burner in the turbulent melting zone.

To provide a method capable of producing granules without complicating the production process even if boric acid is not used. The method for producing glass raw material granules has a step of granulating, in the presence of water, a glass raw material composition (A) which comprises from 45 to 75 mass % of silica, from 3 to 30 mass % of aluminum hydroxide and from 0.4 to 4.6 mass % of an alkali metal hydroxide.
