Method of producing precision shaped apertures in glass is shown. A hollow glass member (10) defining a longitudinal aperture (12) is provided. A carbon graphite member (14) is shaped externally to a desired shape, disposed within the longitudinal aperture (12) in the glass member (10), which member (10) is thereafter collapsed about the graphite member (14) taking its shape and size. The graphite member (14) is removed leaving the glass member (10) with a precision aperture therein. |
