A curved glass manufacturing method includes: successively stacking a lower mold, flat glass, and an upper mold, thereby forming a mold assembly; moving the mold assembly to a first chamber and then heating the same; moving the mold assembly from the first chamber to a second chamber and then pressurizing the upper mold so as to move the upper mold downward, thereby molding the flat glass in a curved shape; moving the mold assembly from the second chamber to a third chamber and then slowly cooling the molded glass; and moving the mold assembly from the third chamber to a fourth chamber and then cooling the molded glass. An elastic member is arranged between the lower mold and the upper mold and configured to define a space between the upper mold and the flat glass, and the elastic member is compressed when the upper mold is pressurized.

In a known method for producing a quartz glass component, a crystal formation layer containing a crystallization promoter is produced on a coating surface of a base body of quartz glass. Starting therefrom, to provide a method for producing a quartz glass component of improved thermal strength and long-term stability which displays a comparatively small deformation particularly also in the case of rapid heating-up processes, it is suggested according to one aspect that a porous crystal formation layer containing amorphous SiO.sub.2 particles is produced with a mean thickness in the range of 0.1 to 5 mm, and that a substance which contains cesium and/or rubidium is used as the crystallization promoter.

Multilayer metallo-dielectric energy control coatings are disclosed in which one or more layers are formed from a hydrogenated metal nitride dielectric, which may be hydrogenated during or after dielectric deposition. Properties of the multilayer coating may be configured by appropriately tuning the hydrogen concentration (and/or the spatial profile thereof) in one or more hydrogenated metal nitride dielectric layers. One or more metal layers of the multilayer coating may be formed on a hydrogenated nitride dielectric layer, thereby facilitating adhesion of the metal with a low percolation threshold and enabling the formation of thin metal layers that exhibit substantial transparency in the visible spectrum. Optical properties of the coating may be tuned through modulation of metal-dielectric interface roughness and dispersion of metal nanoparticles in the dielectric layer. Electrical busbars and micro-nano electrical grids may be integrated with one or more metal layers to provide functionality such as de-icing and defogging.

Provided are methods of forming stacks comprising a substrate and one or more sol-gel layers disposed on the substrate. Also provided are stacks formed by these methods. The sol-gel layers in these stacks, especially outer layers, may have a porosity of less than 1% or even less than 0.5%. In some embodiments, these layers may have a surface roughness (R.sub.a) of less than 1 nanometers. The sol-gel layers may be formed using radiative curing and/or thermal curing at temperatures of between 400° C. and 700° C. or higher. These temperatures allow application of sol-gel layers on new types of substrates. A sol-gel solution, used to form these layers, may have colloidal nanoparticles with a size of less than 20 Angstroms on average. This small size and narrow size distribution is believed to control the porosity of the resulting sol-gel layers.
