COMPLETE SPECIFICATION.
Improvements in and relating to Ornamenting Glass, Transparent
Material, and the like.
I, EDGAR JOHN LUTWYCHE, of 18-30, West Randolph Street, Chicago, in the
County of Cook and State of Illinois, in the United States of America, Artisan, 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:
My present invention relates to the manufacture of transparent materials and
has for its object the production of ornamented articles, such as glass, tiles,
panels, mosaics and the like for architectural purposes and other ornamental and
decorative uses and consists in certain improvements which will be fully disclosed
in the following specification and claims.
In the accompanying drawings which form part of this specification:-
Figure 1 represents a section of a tile on an enlarged or exaggerated scale.
Figure 2 a front elevation or plan view.
Figure 3 a rear elevation or plan view.
Figure 4 a section on an enlarged scale showing a modification of the
construction.
Figure 5 a front elevation or plan of the same.
Figure 6 a rear elevation or plan and
Figure 7 a section of a modified construction.
Reference being had to the drawings and the letters thereon, A indicates a tile,'
panel or mosaic, which is used for the purpose of illustration, as many forms or
designs may be used and are all within the scope of my invention. The back a of
the tile is crimped, rippled or corrugated, as shown in Figures 1, 2 and 3 which
permits the air under the tile to escape in setting in plastic material or roughened
or stippled as shown in Figures 4, 5 and 6, and the front b is preferably smooth,
but may also be of the same configuration as the back as shown in Figure 7, or the
front may have figures differing from the back.
The articles having been properly cleansed, are laid upon a suitable table for
the purpose, heated, and the well known compound solution nitrate of silver,
ammonia and tartaric acid poured on one side, preferably the back of the article,
and after having been permitted to stand a sufficient length of time to effect
precipitation of the silver, the remaining liquid is poured off, the silvered surface
thoroughly rinsed with water and the article allowed to dry or a coating of brilliant
metallic paint, leaf silver, tin or other metal may be applied to the back of the
article. The silver coating c is then covered or backed with a lead or metallic
paint d or with asphaltum.
The tiles, panels, mosaics or other articles are made of tinted or coloured trans-
parent or translucent material such as glass, or bleached rosins and similar
substances, any colour, shade or tint being used, except crystal or flint glass and
when one side is coated with the brilliant material, the opposite side presents. the
appearance of gold, onyx, opal mother of pearl and other coloured ornamentation
upon the glass, and as light falls upon the glass the roughened surface reflects the

page_text: light in a variety of angles and hues and produces a highly ornamental and
pleasing effect.
Any of the known formulas for depositing silver may be used.
The ornamental tiles, panels or mosaics are designed for mural decorations, also
inside and outside architectural tiles or panels representing gilded iron, marble,
onyx, opal and other beautiful and precious or valuable stones and are capable of
being made in a great variety of designs by molding the molten glass into any
shape desired and in a great variety of colors.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed; I declare that what I
claim is:-
First. A tile, panel, mosaic or other article of tinted or colored transparent
material having an irregular surface on one side, and one side coated with a
precipitate from nitrate of silver.
Second. A tile, panel, mosaic or other article of tinted or colored transparent
material having an irregular surface on one side extending throughout the length
and width of the tile and one side covered with a brilliant material.
Third. A tile, panel, mosaic or other article of tinted or colored glass having an
irregular surface on both sides and one of said sides coated with a brilliant
material.
Fourth. The method of ornamenting glass, which consists in tinting or coloring
molten glass, forming tile, panels, mosaics or other articles by molding the article
with an irregular surface and depositing silver in solution on one side of the
article.
