| PROBLEM TO BE SOLVED: To provide an optical component of synthetic quartz glass optimized with respect to compaction and central birefringence. SOLUTION: The production method for an optical component of synthetic quartz glass includes subjecting a quartz glass blank to a multistage annealing treatment comprising the processes of: (a) a first treatment phase during which the quartz glass blank is treated in an upper temperature range between 1,130°C and 1,240°C; (b) cooling the quartz glass blank at a first-higher-mean cooling rate to a quenching temperature below 1,100°C, a fictive temperature with a high mean value of 1,100°C or more being reached in the quartz glass; and (c) a second treatment phase which comprises cooling of the quartz glass blank at a second-lower-mean cooling rate, and in which the quartz glass blank is treated in a lower temperature range between 950°C and 1,100°C such that a fictive temperature is reached in the quartz glass with a low mean value which is at least 50°C lower than the high mean value of the fictive temperature according to the process (b).

| PURPOSE: To reduce cracks of glass containers without prolonging heat treatment time in producing glass containers by evacuating the interior while heating by controlling glass containers under specific pressure during rise and drop in temperature. CONSTITUTION: In producing a container consisting at least partially of glass such as telereceiver by evacuating the interior while heating, atmospheric pressure or higher than the atmospheric pressure is applied to the outside of the container during temperature rise in heating to suppress tension occurring in the inner face. Pressure applied to the outside of the container is reduced during temperature dropping in such a way that pressure difference between pressure at the outside of the container and pressure at the inner side is reduced so that stress resulting from pressure difference between the outside and inside is not produced to reduce tension occurring at the outside.

| In illustrative implementations of this invention, a crucible kiln heats glass such that the glass becomes or remains molten. A nozzle extrudes the molten glass while one or more actuators actuate movements of the nozzle, a build platform or both. A computer controls these movements such that the extruded molten glass is selectively deposited to form a 3D glass object. The selective deposition of molten glass occurs inside an annealing kiln. The annealing kiln anneals the glass after it is extruded. In some cases, the actuators actuate the crucible kiln and nozzle to move in horizontal x, y directions and actuate the build platform to move in a z-direction. In some cases, fluid flows through a cavity or tubes adjacent to the nozzle tip, in order to cool the nozzle tip and thereby reduce the amount of glass that sticks to the nozzle tip. | ||||||

| A process for the reuse of waste glass at relatively low temperatures to create commercial glass products. The steps of the process include filling a tray with waste glass, placing the tray inside a kiln, heating the kiln to a sequence of stages, each stage having a designated temperature and a designated time interval, the stages including initial heating, soaking, annealing and then reducing the temperature to reach ambient temperature. The tray is then withdrawn and a glass block is taken out of the tray. The glass block is then precision cut to create a commercial glass product. | ||||||

| Ternary chalcogenide glass materials containing germanium can display enhanced properties compared to corresponding binary chalcogenide glass materials lacking germanium. For instance, ternary chalcogenide glass materials containing germanium, arsenic and selenium can exhibit improved Vickers micro-hardness values and other enhanced mechanical properties while still maintaining small changes in refractive index as function of temperature. Such ternary glass materials can have a formula of (AsySez)[(100-x)·0.01]Gex, in which x ranges between about 1 and 5, y ranges between about 30 and 40, z ranges between about 60 and 70, and y+z=100. Methods for producing the ternary glass materials can include blending arsenic, selenium, and germanium as a melt, and cooling the melt to form the ternary glass material. | ||||||

| Silica-titania glasses with small temperature variations in coefficient of thermal expansion over a wide range of zero-crossover temperatures and methods for making the glasses. The method includes a cooling protocol with controlled anneals over two different temperature regimes. A higher temperature controlled anneal may occur over a temperature interval from 750° C.-950° C. or a sub-interval thereof. A lower temperature controlled anneal may occur over a temperature interval from 650° C.-875° C. or a sub-interval thereof. The controlled anneals permit independent control over CTE slope and Tzc of silica-titania glasses. The independent control provides CTE slope and Tzc values for silica-titania glasses of fixed composition over ranges heretofore possible only through variations in composition. | ||||||
