Abstract
The forming tool with a special structuring surface includes a reusable ceramic base tool and a replaceable metallic forming member releasably attached to the base tool and provided with a structuring surface for forming a structure in the plate glass. When the comparatively rapidly wearing forming member must be replaced, especially when structuring to form structures with sharp edges, only replacement of the metallic forming member is necessary. This two-component structure also provides additional freedom regarding selection of materials for the base tool and the structuring surface. Thus the base tool can have a comparatively smaller thermal expansion and/or conductivity and the forming member can have a comparatively higher thermal conductivity.
