Abstract: A translucent block includes a pair of parallel upper and lower surfaces each having a generally pentagonal shape. There are a pair of generally rectangular, nonparallel side faces whose planes intersect to form a dihedral angle at 45.degree.. A generally rectangular first opposing end wall is joined to the upper and lower surfaces and is perpendicular therewith, and is joined to the side faces proximal to the vertex of the 45.degree. dihedral angle. A second opposing end wall is formed of two equal sections joined at an obtuse angle to each other. The vertex of the obtuse angle points away from the first end wall, and the sections of the second end wall are perpendicular to and are joined to the upper and lower surfaces of the block and are joined to the nonparallel side surfaces of the block distal from the 45.degree. dihedral angle. The translucent block can be joined to similar translucent blocks and/or different translucent blocks to form a wide variety of wall structures of 45.degree.

Abstract: A translucent end block which may be secured to an exposed side or top abutting surface of a translucent block includes a pair of parallel upper and lower surfaces spaced from each other and having generally the same preselected shape. A pair of side walls extend between the upper and lower surfaces and are joined to the upper and lower surfaces. The pair of side walls each have first wall portions positioned in parallel, spaced relation with each other and nonparallel second wall portions. A first end wall is positioned between the pair of side walls first wall portions and is joined to the upper and lower surfaces and to the pair of side walls first wall portions. The end block is secured to an exposed side or top abutting surface of a translucent block which forms a part of a translucent block wall structure to provide a translucent block wall structure having usable top or side surfaces.

Abstract: A translucent end cap which may be secured to an abutting side surface of a translucent block includes a pair of parallel top and bottom surfaces each having generally the same preselected shape. A side surface extends between the top and bottom surfaces and is perpendicular and joined to the top and bottom surfaces. The side surface has a contour generally conforming to the preselected shaped of the top and bottom surfaces. A raised rear surface portion extends from the side surface to form a protrusion. A portion of this protrusion is arranged to abut a portion of an abutting side surface of a translucent glass block to provide a mortar joint between the end capside surface and the abutting side surface of a translucent glass block. The end caps are secured to exposed top or side abutting surfaces of translucent blocks form a translucent block wall structure to provide a translucent block wall structure having usable top or side surfaces.
