One of the objects of my invention> is to pro vide an improved facing for building construc tions embodying theuse of a sheet of glass for 5 the exposed face, the facing having anchorage means for securing it to a plastic support. A further object of my invention is to provide such a construction in which the anchorage , means are secured to the sheet of glass by the 10 fusion ofa layer of colored vitriflable material. A further object is to provide such a construc tion in which the coloring material will be pro tected. ' ' - A further object is to provide such a construc 15 tion in which the facing will be securely anchored to the support. . material, may be secured together as a unit by 4 fusion, as by inserting it into a kiln or lehr at a' suitable temperature. The'vitriñable material and the sheet of glass shouldl have such fusing char acteristics that thev layer of -vitriflable material' 5 will fuse-at a somewhat lower temperature than the sheet of glass, thus avoiding softening- and bending of the sheet of glass. The particles of grit form. an anchorage for the panel by means of which it may be secured to any suitable plastic 10 backing, as will be described in detail hereinafter. It may sometimes. be desirable to provide two layers of the colored vitriflable material,- the first layer _being applied and fused to the sheet vof glass, and the second layer, with the anchorage material, being thereafter applied.
