COMPLETE SPECIFICATION.
An Improvement connected with Glass Tiles or Slabs for
Architectural and like uses.
I, JAMES TYRRELL NEWELL, of 184, Warham Street, Kennington Park, Surrey,
Lithographic Printer, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
This invention has for object, a special treatment of sheets or pieces of glass
to render them applicable for walls, panels, and the like for architectural purposes.
For my invention, I employ a ceramic glaze or paste (white or in colour)
brushed or rolled, or otherwise applied on one side only of a piece or sheet of, say,
clear or opaque glass, and either all over such side of the piece or sheet, or at
places only, I apply ceramic glaze or paste (white or in colour), on to which
either by sprinkling, dipping, or otherwise, cause roughly ground or broken
glass or suitable material, such as sharp coarse sand, to cover the ceramic glaze
or paste (white or in colour) as to lodge on the surface and temporarily adhere to
it, and then by the firing process to become associated as part of the glass itself,
or the removal of the so coated glass, the broken or granulated particles appear
prominently therefrom and serve as a key for adhesion of Portland cement as
a backing thereto, and the colour of the ceramic glaze or paste applied as desired
gives the tone to the glass, if required, any shade of colour can be applied
giving a coloured tile with a rough backing ready for fixing, the glass thus
prepared being specially adapted as tiles or slabs for walls, panels, and surfaces
generally for which glazed bricks are now used to reflect light into dark passages.
The glass tiles or slabs of the foregoing invention are well adapted for all kinds
of outside exposed walls but are particularly serviceable in cellars, in sculleries,
pantries, and cupboards generally, as from the closeness of fit, edge to edge, it
is impossible for vermin to harbour in cracks, or to burrow through.
For harness rooms, stores, and like places where dryness is essential, the tiles
or slabs are of importance, being impervious to dampness, fungi and mildew do
not form thereon.
The glass, if only partially coated or smeared with the ceramic glaze or paste
(white or in colour) and with only those parts prepared with the granulated glass
as the key to a cement backing allows for expansion and contraction of the glass
in the firing and after cooling operation without risk of fracture or distorting
its shape, and by applying patterns of marble in the ceramic colours, the tile can
also be made with key sprinkled on to the colours.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
1 claim is:
1. Treating glass with ceramic glaze or paste (white or in colour) and sprinkling
same with granular substances and fixing same by heat, as and for the purpose
1

page_text: 2. In the manufacture of glass tiles or slabs, the employment of ceramic glaze
or paste (white or in colour) wholly or on part of one face only, and coating said
glaze or colour with granulated glass or suitable material, which when fired
remains as a roughened surface thereon, and serving as a key for the affixture of
a cement backing, as described.
3. In the manufacture of glass faced tiles or slabs, the combination of sheet
glass, ceramic glaze or paste (white or in colour), and granulate glass or suitable
material so fired as to constitute a single body with a very rough surface as a
key for the adhesion of Portland or like cement, as a backing thereto, as set
forth.
