Abstract: A method of manufacturing including: with a porous glass body having a surface and a density at the surface having been loaded into a furnace with heating elements disposed along a length of the porous glass body, a first heat treatment step comprising activating the heating elements until the porous glass body at an inner surface of the porous glass body facing a centerline of the porous glass body has a first temperature that is greater than or equal to 1250° C. for a first period of time greater than or equal to 1 hour; wherein, as a result of the first heat treatment step, the density of the porous glass body at the surface increases but is less than 85% of a closed pore density of a sintered glass preform made from the porous glass body.

Abstract: Apparatuses and methods for processing an optical fiber preform are disclosed. According to one aspect, an apparatus may generally include a muffle defining an interior volume enclosed by at least one sidewall and a handle assembly for supporting the optical fiber preform in the muffle. The handle assembly may be removably coupled to the muffle and extend into the interior volume. At least one baffle may be positioned in the interior volume and define an upper portion of the interior volume and a lower portion of the interior volume. The at least one baffle may define at least one flow channel between the upper portion of the interior volume and the lower portion of the interior volume.

Abstract: A fusion down-draw method for making a glass sheet using a forming body comprising an upper part (101) made of a first material and a lower part (103) made of a second material, where the first material has lower creep rate than the second material at the normal operating temperature of the forming body, and an fusion down-draw forming apparatus comprising such forming body. The invention is advantageous in that it solves the issues of internal stress and long-term creep issue of a unitary forming body made of a single material such as zircon.

Abstract: A method and apparatus for forming a glass sheet using a fusion down-draw process, wherein the heating powers of the heating elements are managed such that in case of a failure of one heating element, the heating power of the adjacent heating element is immediately increased. The method decreases the thermal stress the forming body is exposed to due to the failure of the heating element.
