The present invention provides a cover glass that can be installed in an automobile so as to cover a display unit including a plurality of information areas, including a glass body that has a first surface facing the display unit side, and a second surface opposite to the first surface, and that includes a plurality of transmission areas respectively corresponding to the information areas.

An apparatus and a method for continuously manufacturing tempered glass are provided. The tempered glass is continuously manufactured by transferring the raw glass in one direction, spraying a boiled potassium nitrate solution to the raw glass to reinforce the raw glass, and recovering and reusing the potassium nitrate solution from the raw glass. This invention can reduce the time to manufacture tempered glass since you can manufacture tempered glass consecutively, and the cost of purchasing potassium nitrate solutions can be reduced, which has an economic advantage. Since the raw glass is preheated, strengthened and annealed by divided sections of preheating, strengthening and annealing section in one furnace, it is less likely that impurities will be attached to the raw glass due to low external exposure during each process movement, thus preventing deterioration of quality.

Methods of screening a glass container for storing a pharmaceutical formulation for susceptibility to lamellar silica formation includes filling the container with a buffer for the pharmaceutical formulation, storing the container with the buffer and optically analyzing the buffer after storage for one or more particles in the buffer. The one or more particles can be analyzed to determine a morphology and chemical composition and the interior surface of the container, once emptied, can be analyzed for delamination type deformation. The presence of particles in the buffer having a chemical comprising silicon, oxygen, and carbon and the absence of delamination type deformation is indicative of susceptibility to lamellar silica formation.

Methods of preventing the formation of lamellar silica formation in a borosilicate glass container storing a pharmaceutical formulation in an interior of the glass container in accordance with embodiments of the disclosure can include washing the container and drying the container under extended dry conditions of at least 3000 ms.

A textured glass article includes: a body comprising an aluminosilicate glass comprising greater than or equal to 16 wt % Al.sub.2O.sub.3 and a Al.sub.2O.sub.3/SiO.sub.2 ratio less than or equal to 0.3, the body having at least a first surface; a plurality of polyhedral surface features extending from the first surface, each of the plurality of polyhedral surface features comprising a base on the first surface, a plurality of facets extending from the first surface, and a surface feature size at the base greater than or equal to 10 m and less than or equal to 100 m, wherein the plurality of facets of each polyhedral surface feature converge toward one another; and a transmittance haze greater than or equal to 50%.
