_.2 claims. (on 'i2-1s)l
My invention relates to building constructions.
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.

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. This use of
the two layers of vitriñable material may be de
