A sensitized, photo-structurable glasses and methods for producing are provided. The glasses includes Si.sup.4+, one or more crystal-agonist, one or more crystal-antagonist, and one or more pair of nucleating agents. The glasses are sensitized in that the glass reacts more sensitive to irradiation with UV-light and can be crystallized easier and with higher aspect ratios than a non-sensitized glass with equal composition. Furthermore, the sensitized glasses of this invention have smaller crystal sizes after irradiation and tempering than a non-sensitized glass with equal composition. The invention also relates to a structured glass product. Such product can be obtained by submitting the crystallized glass product to a subsequent etching step. The structured product can be used in components or as component for the application fields micro-technology, micro-reaction-technology, electronic packaging, micro-fluidics, FED spacer, bio-technology, interposer, and/or three-dimensional structured antennae.

A process and an apparatus for imparting coloration to a glass container having a strikable glass container composition. One or more portions of the glass container are selectively and locally exposed to a temperature at or above a glass container striking temperature to affect a color change in the one or more portions of the glass container. The coloration process may be carried out by passing the glass container through an interior of an apparatus having a heating system configured to locally heat a first region within the interior to a temperature at or above a glass container striking temperature and a cooling system to locally cool a second region within the interior to a temperature below the glass container striking temperature.

An optical component made of synthetic quartz glass includes a glass structure substantially free of oxygen defect sites and having a hydrogen content of 0.110.sup.16 to 1.010.sup.18 molecules/cm.sup.3, an SiH group content of less than 210.sup.17 molecules/cm.sup.3, a hydroxyl group content of 0.1 to 100 wt. ppm, and an Active temperature of less than 1070 C. The optical component undergoes a laser-induced change in the refractive index in response to irradiation by a radiation with a wavelength of 193 nm using 510.sup.9 pulses with a pulse width of 125 ns and a respective energy density of 500 J/cm.sup.2 at a pulse repetition frequency of 2000 Hz. The change totals a first measured value M.sub.193 nm when measured using the applied wavelength of 193 nm and a second measured value M.sub.633 nm when measured using a measured wavelength of 633 nm. The ratio M.sub.193 nm/M.sub.633 nm is less than 1.7.
