The present invention relates to a method for manufacturing an exterior part for a timepiece or piece of jewelry made of Murano glass, said method comprising the following steps: providing a material formed of glass rods (2), also referred to as glass tubes, arranged side by side; multi-cycle heat treatment to consolidate the material and form a blank; machining the blank to produce the exterior part, the method being characterised in that the heat treatment comprises a first cycle (a) consisting of heating the material from a temperature less than or equal to 100° C. to a temperature between 450 and 650° C. at a heating rate between 4 and 12° C./min in order to avoid the formation of air bubbles during the manufacturing of the blank. It also relates to the exterior part for a timepiece or piece of jewelry, in particular a watch case, having a structure with few or no air bubbles.

A method may include (1) coating a segment of fiber optic cable with an adhesive substance, (2) forming a coil of the segment of fiber optic cable, (3) deforming the coil into a noncircular shape defining a slot external to the coil while obeying a minimum bend radius requirement for the segment of fiber optic cable, and (4) activating the adhesive substance to stabilize the noncircular shape of the coil. Various other methods and apparatuses, such as those for performing the deforming operation, are also disclosed.

Disclosed are a glass fiber tape, a surface modification method and an application thereof. The surface modification method includes the determination of an optimal decarburizing condition of the glass fiber tape, the decarburization of the glass fiber tape, and the coating of palmitic acid.

A glass container has an outer glass surface with an inkjet printed image provided on the surface. A cold-end coating (CEC) with a thickness between 0 to 20 nm is present between the outer glass surface and the inkjet printed image. Such glass container is preferably a one-way beverage bottle. A method of inkjet printing an image on a glass container comprises the steps of (a) manufacturing a glass container having a CEC layer; (b) removing at least part of the CEC layer to a level wherein the remaining CEC layer has a thickness of 0 to 20 nm; and (c) inkjet printing an image on the glass container.

The present disclosure provides a method for modification of surface of an initial optical fiber preform. The initial optical fiber preform is manufactured using at least one preform manufacturing process. The surface of the initial optical fiber preform is treated with 50-70 liters of chlorine per square meter of the surface of the initial optical fiber preform. The surface of the initial optical fiber preform is flame polished using a flame polishing module. The treatment of the surface of the initial optical fiber preform with chlorine and flame polishing of the surface of the initial optical fiber preform collectively converts the initial optical fiber preform into a modified optical fiber preform.
