Abstract: A method of replicating at least one optical element is provided, the method including the steps of: providing a substrate with two large sides and at least one pre-defined replication site defined by a through hole or blind holes at corresponding locations on both large sides of the substrate; and adding, by replication, a replicated structure to the substrate, the replicated structure adhering to the substrate and having, at the replication site, replication material in the through hole or in the two blind holes, respectively and a first replicated surface and a second replicated surface, the first and second replication surfaces facing towards opposite sides.

Abstract: A stack structure is formed by stacking and bonding a plurality of substrates. The stack structure includes bonding films each of which is interposed in a bonding region between, adjacent glass substrates, and bonded to oxygen atoms in the glass of the substrate by anodic bonding.

Abstract: Method and plant to make tesserae (11) for glass mosaic, containing ornamental metal foil (14) inside. The method comprises the steps of positioning a first glass strip (30), with a metal foil (14) associated above, on a work plane (20) including first molding means (22), localized heating of the work plane (20) to obtain a softening of the first glass strip (30), casting a quantity of glass onto the metal foil (14), pressing the semi-worked product (29) in its plastic state, and molding the semi-worked product (29) to define the contours of the tesserae (11), by means of cooperation between second molding means (19) and the first molding means (22). One or more of the steps are performed sequentially in at least one work station (40-49).

Abstract: A process for fabricating glass art, comprising the steps of: (a) providing a first substrate and a second substrate, wherein each of the first and second substrates comprises an upper surface and a lower surface; (b) providing at least one wire, wherein the at least one wire comprises a first end, a second end, and a length therebetween; (c) associating the first end of the at least one wire with the lower surface of the first substrate and the upper surface of the second substrate; (d) heating the first and second substrates and the at least one wire from ambient temperature to an elevated temperature ranging from approximately 1,000 degrees Fahrenheit to approximately 2,000 degrees Fahrenheit over a period of time ranging from approximately 0.

Abstract: A method of providing a decorative metal pattern on an electrically non-conductive substrate, such as a glass or plastic substrate, which includes applying a mixture of heat fusible material, such as glass or plastic, with a metal having a particle size less than about 500 mesh constituting at least 50% of the mixture, to the substrate in the desired pattern, heating the so-applied mixture until the heat fusible material fuses and bonds to the substrate, cleaning the substrate with the pattern thereon, and a electroplating the pattern with the desired finish metal. In one method in which the mixture includes glass, a negative resist is adhesively secured to the substrate and the mixture is applied. The resist disintegrates upon heating. In another method, used when the substrate is plastic, a mixture of plastic and metal in past form is applied to the substrate by silk screening or pad printing to form the pattern.

Abstract: A known method for producing an object having a flanged tubular portion at the outer periphery, comprises supplying a continuously extended, cylindrical body made of the flange material to a welding zone at the tubular portion of the object and welding the flange material to the welding zone by heating and winding the cylindrical body around the object.
