Improved Means or Process for Operating upon Glass for General
Ornamentation and Embellishment Purposes.
We, ARTHUR AUGUSTUS GIBBS, SARAH ANN GIBBS, and WALTER
THOMAS GIBBS, all of 2 Charlotte Street, Blackfriars Road, County of London,
Glass Embossers do hereby declare the nature of the said invention to be as
follows:-
This invention has for object improved means or process for operating upon
glass for general ornamentation and embellishment purposes.
If it be desired to produce shaded embossing with clear bright outline to
ornament with a silky stained background at the same time being obscured, we take
the plain glass on which we lay a coat of acid resist. We then remove the resist
with the aid of a stencil from the parts forming the background to any design we
desire to produce. We then pour upon the surface a solution of soda and fluoric
acid which has the effect of laying a white mat upon all unprotected parts; the
solution is then removed and the glass allowed to dry.
We then brush away the scum left from the solution and pour upon the surface
fluoric acid which we allow to remain till the depth required to produce a rich silky
white; the resist is then removed with mineral oil and the glass thoroughly
cleaned.
We then lay a coat of stain over the surface and with the aid of a steel straight
edge we remove the stain from the ornament leaving the stain in the background
which has previously been indented by the process above described, thus protecting
it from the action of the straight edge when drawn over.
We then place the glass in the kiln to burn the stain into the glass.
When the glass is taken from the kiln it is thoroughly cleaned and the outline
traced on the clean glass, and the background filled in with acid resist.
We again pour on the surface the solution of soda and fluoric acid, and so lay a
white mat on the whole of the ornament, leaving the outline, which is protected by
the resist, clear.
We then proceed to shade in, according to the customary manner of the trade.
When the shades are completed we remove the resist with mineral oil.
If it be desired to produce out of stain, a shaded embossing with clear stain out-
line, we take the plain glass, on which we lay a coat of stain, we then with a
'stencil, remove the stain from the parts forming the back ground, leaving the
ornament intact, the glass is then placed in the kiln; and the stain burnt in. After
passing through the kiln, we trace the outline of the ornament, which we desire to
leave in the clear stain, with embossing black, or other acid resist. We'then pour
on the surface, a solution of sodn and fluoric acid, which has the effect of laying a
white mat on all the unprotected parts. After the solution is removed, and the
glass has been thoroughly dried, we brush away the scum left from the solution, wo
then put on the ornament, what is known, as a shade, at the same time filling in the
ground, leaving a shade under the ornament unprotected. We then pour upon the
surface, fluoric acid, which we allow to remain till the tone is the strength required.
After this has been allowed to dry, the scum is removed, as before; we then fill in
the whole of the background with resist, which at this stage of the process is
finished, leaving only the ornament to work upon. We then proceed to take
another shade from the ornament, as previously described this is repeated till the
last shade becomes white, or could be finished at any stage after the first shade, if
desired. When shades are completed, we clean off the resist with mineral oil, when

the ormanent gradually shaded from dull gold to a silky white, whilst our back-
ground will be white with a shade under design.

Glass Embossers, 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 improved means or process for operating upon glass
for general ornamentation and embellishment purposes.
If it be desired to produce shaded embossing with clear bright outline to
ornament with a silky stained background at the same time being obscured, we take
the plain glass on which we lay a coat of acid resist. We then remove the resist
with the aid of a stencil from the parts forming the background to any design we
desire to produce. We then pour upon the surface a solution of soda and hydro
fluoric acid which has the effect of laying a white mat upon all unprotected parts ;
the solution is then removed and the glass allowed to dry.
We then brush away the scum left from the solution and pour upon the surface
hydro fluoric acid which we allow to remain till the depth required to produce
a rich silky white; the resist is then removed with mineral oil and the glass
thoroughly cleaned.
We then lay a coat of stain over the surface, and with the aid of a steel straight
edge we remove the stain from the ornament, leaving the stain in the background
which has previously been indented by the process above described, thus protecting
it from the action of the straight edge when drawn over.

We again pour on the surface the solution of soda and hydro fluoric acid, and so
lay a white mat on the whole of the ornament, leaving the outline which is protected
by the resist, clear.
We then proceed to shade in according to the customary manner of the trade.
When the shades are completed we remove the resist with mineral oil.
The staining process can be applied to brilliant cutting.
If it be desired to produce out of stain, a shaded embossing with clear stain
out-line we take the plain glass, on which we lay a coat of stain, we then with a
stencil remove the stain from the parts forming the back ground, leaving the
ornament intact, the glass is then placed in the kiln, and the stain burnt in. After
passing through the kiln, we trace the outline of the ornament, which we desire to

We then pour
on the surface a solution of soda and hydro fluoric acid which has the effect
of laying a white mat on all the unprotected parts.. After the solution is removed
and the glass has been thoroughly dried, we brush away the scum left from the

removed as before; we then fill in the whole of the background with resist, which
at this stage of the process is finished, leaving only the ornament to work upon.
We then proceed to take another shade from the ornament, as previously
described, this is repeated till the last shade becomes white, or the glass previously
prepared as above could be finished at any stage' after the first shade, if desired..
When shades are completed, we clean off the resist with mineral oil when we have
upon the glass a design with a clear gold or amber out-line, and the interior of the
ornament gradually shaded from dull gold or amber to a silky white, whilst our
back ground will be white or clear with a shade under design.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed we declare that what we
claim is :-
