Fusing glass articles
A method of forming a glass article is provided. The method includes the steps of positioning a first interface surface of a first glass block proximate a second interface surface of a second glass block to define an interface seam, welding the first and second glass blocks together around a majority of the interface seam to define an internal cavity, coupling a vacuum fitting to at least one of the first and second glass blocks, drawing a vacuum in the cavity between the first and second glass blocks, and heating the first and second glass blocks to fuse the first and second glass blocks together.
