A method for further processing of a glass tube semi-finished product includes: providing the glass tube semi-finished product, along with tube-specific data for the glass tube semi-finished product; reading the tube-specific data for the glass tube semi-finished product; and further processing of the glass tube semi-finished product including a step of thermal forming carried out at least in sections. At least one process parameter during the further processing of the glass tube semi-finished product including the step of thermal forming carried out at least in sections is controlled as a function of the tube-specific data for the glass tube semi-finished product. In this way, the further processing can be matched more efficiently to the particular characteristics of a glass tube semi-finished product to be processed or a particular subsection thereof, and the relevant characteristics of the particular glass tube semi-finished product do not need to be measured again.

A glass plate includes a first surface and a second surface that is opposite to the first surface. A concave portion is formed on the first surface toward the second surface side with reference to the first surface. A convex portion is formed on the first surface toward a side opposite to the second surface with reference to the first surface.

There are provided a one-press manufacturing method for a glass container that can form uneven shapes on an inner peripheral surface of a glass container and a glass container that is obtained by the one-press manufacturing method. The one-press manufacturing method for a glass container includes the following steps (A) to (E); (A) a step of putting a gob in a pressing mold and then inserting a plunger, which includes an unevenness forming member provided so as to be capable of being received in the plunger, into the gob while the unevenness forming member is received in the plunger, (B) a step of forming a glass container having a finished shape, which includes an uneven shape on an inner peripheral surface thereof, by pressing the unevenness forming member against the surface of the gob, which comes into contact with the unevenness forming member, to the outside from the inside of the plunger, (C) a step of receiving the unevenness forming member in the plunger, (D) a step of extracting the plunger, in which the unevenness forming member is received, from the glass container having a finished shape that includes the uneven shape on the inner peripheral surface thereof, and (E) a step of transporting the glass container having a finished shape, which includes the uneven shape on the inner peripheral surface thereof, to a cooling mold and cooling the glass container having a finished shape.

An article includes a glass substrate and an insert within the glass substrate, the surface roughness (Ra) of the glass substrate and the insert is about 0.05 m to about 0.2 m.

The present disclosure provides a method for manufacturing an aspherical prism and an aspherical prism. The method includes step S1, forming a prism and a lens into one piece to obtain a forming body glass by using a hot-pressing molding; step S2, adhering the forming body glass to a tooling, and performing a right-angle surface milling on the forming body glass according to a preset size while reserving a processing amount for a polishing process; step S3, adhering the forming body glass formed after the right-angle surface milling to an optical backing plate for polishing; step S4, cutting the forming body glass formed after the polishing; step S5, coating the forming body glass formed after the cutting; and step S6, inking the forming body glass formed after the coating. The method can improve the structural precision and processing efficiency of the aspherical prism.
