Abstract: A method for forming a honeycomb structure from glass tubes and the resulting article including arranging the tubes in a stack, heating the stack, and maintaining the interstitial spaces of the stack at a predetermined gas pressure no greater than that of the remainder of the stack, in order to radially expand the individual tubes of the stack and reduce the cross sectional size of interstitial spaces between tubes a predetermined amount. The method can be used to change the cross sectional shape of a round tube of the stack to other shapes such as hexagonal or square.
