Abstract
The present invention relates to a novel sealing glass composition, in particular, one which comprises solid PbO--ZnO--B.sub.2 O.sub.3 glass and natural garnet as a filler component. This composition has the advantage that thermal strain does not occur at the interface between the crystalline glass and filler because of the excellent chemical affinity. This prevents cracks from propagating at the interface between the main glass and filler, thereby improving the mechanical strength of the glass.
