A hollow enclosure has first and second ceramic walls interconnected and hermetically sealed by first and second compact coupling assemblies. In one form, each coupling assembly includes a first flange portion, a web portion and second flange portion. The first flange portion of the first coupling assembly is fritted to a first annular edge of the first ceramic wall. The first flange portion of the second coupling assembly is fritted to a second annular edge of the second wall. The second flanges of the coupling assemblies are then placed against one another and laser welded, without the need for thermal clamps.
