Abstract

A smoothing iron sole includes a sole body comprised at least partly of a glass material. A heating conductor is mounted on a glass-material surface of the sole body facing a sole surface and the sole further includes a thin fabric layer of heat-resistant fibers covering the glass-material surface for defining the sole surface. The heat-resistant fibers are sealed and closed off relative to the heating conductor arrangement by a heat-resistant connecting material which is firmly bonded to the glass-material surface. In one embodiment the heat-resistant fibers are glass fibers and in another they are boron carbide. The connecting material has a melting point which is lower than that of the heat-resistant fibers.
