Abstract
A vacuum insulated glass (VIG) panel includes a first glass panel and a second glass panel spaced from the first glass panels. A spacer is disposed between the first and second glass panels. The spacer includes first and second generally opposed faces, and a plurality of sides extending therebetween. The spacer is processed using tumbling and polishing operations to preferably round all corners of the spacer and form a circular contact footprint on opposed side faces of the spacer. The spacer surface break conditions are measured during tumbling and/or polishing operations using optical flat measuring equipment. Following the polishing operation the spacer is thermally processed to strengthen the spacer.
