ORNAMENTAL GLASS." [A communication from abroad by James Budd and Jott
Graut, both of Boston, Massachusetts, United States of America.]
This Invention relates to the production of ornamental glass, which may be
either semi-transparent or opaque, and is according to the said Invention made to
represent highly polished wood of any known variety, and which is applicable for
veneering wherever required, and is particularly adapted for vestibule and other
doors, the exterior of the glass having the appearance of highly polished wood,
while in the interior of the house it will be semitransparent.
In carrying the said Invention into practice, I take a sheet of ground or plain
glass of any desired size and cloud the same on one side with a liquid dye of the
proper color to represent any desired wood, which dye is applied by means of a
sponge for delineating the grain of the wood so as to appear upon the surface of
varuish is then caused to flow on the glass and leaves the grain clear and fast
without the necessity for using any gelatinous substance, which would render it
liable to crack and spoil the effect. To complete the operation the glass is then
slightly heated, and the various shades of dyes required for the particular wood to
represented are caused to flow over by means of a syringe. The glass is heated

in order to prevent the shadings from merging into each other. The whole is
then made semitransparent by applying another coating of photographers' varnish

substance with various dry colours, using for the purpose a piece of cork, by which
means a hard porcelain backing is produced capable of resisting the strongest
acids. The backing of the opaque veneer prevents "sweating" when used in it

The said Invention is applicable for very general use as a substitute for varnished
and polished woods as a veneer in the finish of all kinds of cabinet work, in the
walls and ceilings of houses, and in the finish of rail way carriages and ships
cabins. The backing may also be used for mirrors, and also for decorations

ORNAMENTAL GLASS."
"IMPROVEMENTS IN THE MANUFACTURE OF
A communication from abroad by James Budd and Jott
Grant, both of Boston, Massachusetts, United States of America.
This Invention relates to the production of ornamental glass, which may be
either semi-transparent or opaque, and is according to the said Invention made to
represent highly polished wood of any description, and which is applicable for
veneering wherever required, and is particularly adapted for vestibule and other
doors, the exterior of the glass having the appearance of highly polished wood,
while in the interior of the house it will appear semi-transparent.
In carrying the said Invention into practice, I take a sheet of ground or plain
glass of any desired size and cloud the same on one side with a liquid dye of the
proper color to represent any desired wood, which dye is applied by means
of a sponge for delineating the grain of the wood so as to appear upon the
surface of the glass. The shading is softened by means of a badger brush.
Photographers' varnish is then caused to flow on the glass and leaves the grain
clear and fast without the necessity for using any gelatinous substance, which
would render it liable to crack and spoil the effect. To complete the operation the
glass is then slightly heated, and the various shades of dies required for the
particular wood to be represented are caused to flow over it by means of a syringe.
The glass is heated in order to prevent the shadings from merging into each other.
The whole is then made semi-transparent by applying another coating of photo-
graphers' varnish so as to prevent the dyes from being effaced, while the exterior
surface presents the appearance of a highly polished solid wood finish.
In making the glass opaque to be used as a veneer, I employ the same process
as above described, with the addition of a backing consisting of a coating of shellac,
into which is rubbed dry powdered plaster of Paris or some equivalent substance
with various dry colours, using for the purpose a piece of cork, by which means a
hard porcelain backing is produced capable of resisting the strongest acids. The
backing of the opaque veneer prevents "sweating" when used in its application
to furniture, walls, and the like.
The said Invention is applicable for very general use as a substitute for
varnished and polished woods as a veneer in the finish of all kinds of cabinet
work, in the walls and ceilings of houses, and in the finish of railway carriages and
ships' cabins. The backing may also be used for mirrors, and also for decorations
on glass in gold.
As no paint or oily substances are used in the process, there is no liability of
peeling or breaking on the glass by age or exposure to heat or to the atmosphere.
Having thus fully described the said Invention as communicated to me by my
foreign correspondents, and the manner of performing the same, I wish it understood
that I claim,-
First. The above described process of ornamenting glass, consisting in applying
to a plate of glass a liquid dye of the proper color to represent any desired wood
shades of dyes to represent the different shades of the wood, subst intially as set
had then applying photographers' varnish, and after heating glass applying various
forth and for the purposes specified.
Second. The use of a coating of shellac, into which is rubbed dry powdered

page_text: plaster of Paris with various dry colors to form a backing for the above described
imitation of wood, substantially as described and for the purposes specified.
Third. The sheets of glass ornamented by the above described process to
represent highly polished wood and serving as a veneer, substantially as specified.
In witness whereof, I, the said Henry Harris Lake, have hereunto set my
hand and seal, this Thirtieth day of May, in the year of our Lord On
thousand eight hundred and eighty two.
