The present invention describes an extrusion process for manufacturing a glass honeycomb structure having a variety of shapes and sizes depending on its ultimate application. Unlike prior art honeycomb structures made from ceramics, the inventive glass honeycomb can be readily viscously bent and/or redrawn. Furthermore, the inventive honeycomb structure is lightweight, yet able to support heavy loads on its end faces. Therefore, the inventive honeycomb can be used as a light-weight support for such objects as mirrors. These honeycombs can be used singularly or in aggregates to provide such support. Embodiments are described wherein the mass of the honeycomb is further reduced by removing select portions of the honeycomb without deleteriously impacting its ability for load bearing.

1. A process of preparing a glass honeycomb article comprising the steps of:a) providing an essentially homogeneous paste comprising a vitreous silicate powder of high purity fused silica soot, a binder, a lubricant, and a solvent, wherein said powder comprises particles of less than about 0.4 micron; b) extruding strands of said paste through a die to form an intermediary article; c) drying said intermediary article in order to remove residual solvent; d) debinding said intermediary article in order to generate a brown honeycomb article; and e) firing said brown honeycomb article to partial or complete sintering thereof.
