A method, an installation and a system for processing optical workpieces in which workpieces are conveyed to individual processing apparatus or processing lines corresponding to an assignment. The respective assignment preferably takes into consideration assignment parameters, such as the availability and capability of processing apparatus and/or processing lines. The assignment that already has been carried out is examined before the actual or ultimate conveying and/or when there is a change in the assignment parameters and optionally is changed in a corresponding manner, taking into consideration the current assignment parameters, in order to adapt to current circumstances. As an alternative or in addition, jobs for processing workpieces are forwarded to the processing installations at different sites based on corresponding assignment parameters. Optionally, an examination and, as appropriate, a change in the assignment are made when new jobs or significant changes in the assignment parameters are detected.

A textured glass-based article with multiple haze levels is provided. The textured glass-based articles are produced by utilizing a combination of etching and mechanical polishing to produce the multiple haze levels.

An antimicrobial glass-based article comprises: a first major surface opposing a second major surface. A first surface region extends 1 micron into the article from the first major surface. The first surface region has an average Ag.sub.2O concentration across the first surface region of equal to or greater than 10 mol % and equal to or less than 30 mol %, and a surface roughness R.sub.a of 100 nm or greater.

Embodiments of the invention disclose a method of producing a portable electronic device cover glass. The method comprises providing a portable electronic device cover glass preform of a predefined thickness, for example ranging from 10 micrometers to 600 micrometers, and texturing a surface of the portable electronic device cover glass preform such that said surface is provided with a roughness that simulates the surface of paper in terms of a user's reading experience and writing experience.

An antiglare glass substrate includes a glass substrate having a first main surface and a second main surface that is opposite to the first main surface. The first main surface has undergone an antiglare treatment and a fluorine-containing organosilicon compound coating film as an antifouling film is laminated thereon. The first main surface partly includes a non-antiglare-treated portion that has not undergone the antiglare treatment. The non-antiglare-treated portion has a surface roughness Ra of less than 10 nm. A difference in height along a plate thickness direction of the glass substrate between the antiglare-treated portion that has undergone the antiglare treatment and the non-antiglare-treated portion is 10 μm or larger and 200 μm or less.
