ABSTRACT:
A method of making a double-walled vacuum container includes the steps of forming a double-walled container from gas-impermeable, radiation transmissive material with spaced-apart inner and outer walls that enclose an interior volume with a lacuna between the inner and outer walls; coating surfaces of the container walls that face the lacuna with a reflective coating; positioning the container in proximity to a source of coherent radiant energy; and removing selected portions of the reflective coating by impinging coherent radiant energy on portions of the reflective coating selected for removal.
