Improved Method of Preparing a Gummy Varnish, Coloured or
otherwise, for General Use or Decorative Purposes.
1, JESSE ALBERT BIGSBY of 3 Chichester Villas, Lower Road Deptford, Kent,
Varnish Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to manufacture transparent coloured oil and spirit
varnishes for application to glass, china, porcelain, wood, metals, or any like
substances, and for mural decorations.
In a varnish composed of one pound of resin, or any gum resin two pounds of
linseed or other equivalent oil and two pounds of spirits or oil of turpentine combined
with a small quantity of any siccative matter, or in any oil or spirit varnish of
commerce, such as those containing gum amine, copals, kauri amber, damar, mastic,
shellac, sandrac, benzoin, or any other resin or gum resin, oil or spirit, I intimately
mix by trituration or solution by heat or any such process from 2 to 8 ounces to
every gallon (according to the shade or depth of colour required) of aniline dye,
mineral, animal, or vegetable colouring matter as shall have proved by previous
experiments to be capable of withstanding a high temperature and the exposure to
strong light and by such admixture or combination of the animal, mineral, and vege-
table matters with the aniline dyes they are thereby fixed and rendered permanent
and impervious to the action of heat and light.
All insoluble matter remaining to be removed by filtration or gravitation and when
applied to glass, china, porcelain, wood, or any like substance, either in a hot or cold
state, produces a more brilliant, superior and equally durable effect, to that produced
by the ordinary method by the admixture of the colouring matter with the glass
before manufacture or by burning in the colours, and when applied to mural decora-
tions or the decoration of wood or metals an effect far more varied and of superior
appearance can obtained by one application than could be obtained even by several
applications by any other method. Moreover as the herein mentioned coloured
varnishes contain no poisonous matter, they are of great sanitary value in internal
domestic decoration.

1 JESSE ALBERT BIGSBY of 3 Chichester Villas, Lower Road, Deptford, Kent,
Varnish Manufacturer do hereby declare the nature of my said invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement:-
The object of this invention is to manufacture transparent coloured oil and spirit
varnishes for application to glass, china, porcelain wood, metals or any like substances
and for mural decorations.
In a varnish composed of 1 lb. of Resin or any gum resin, 2 lbs. of Linseed or other
equivalent oil, and 2 lbs. of spirits of oil of turpentine combined with a small quantity
of any siccativo matter or in any oil or spirit varnish of commerce such as those con-
taining Gum Anime, Copals, Kauri. Amber Damar, Mastic, Shellac, Sandrac Benzoin
or any other resin or gum resin, oil or spirit. I intimately mix by trituration or
solution by heat or any such process from 2 to 8 oz. to every gallon (according to
the shade or depth of color required) of Aniline Dye, Mineral Animal or Vegetable
colouring matter as shall have proved by previous experiments to be capable of with-
standing a high temperature and the exposure to strong light such as Chinese Blue,
Prussian Blue, Induline, Aniline Blue, Gamboge or Aniline Yellow Lake, Aniline
Orange, Persian Red, Aniline Scarlet, Scarlet Lake, Bismark and Asphaltum Brown
and by such admixture or combination of the animal, mineral or vegetable matters
with the aniline dyes they are thereby fixed and rendered permanent and impervious
to the action of heat and light all insoluble matter remaining to be removed by filtra-
tion or otherwise and when applied to glass, china porcelain, wood or any like
substance either in a hot or cold state, produces a more brilliant, superior and equally
durable effect to that produced by the ordinary method by the admixture of the
colouring matter with the glass before manufacture or by burning in the colors, and
when applied to mural decorations or the decoration of wood or metals, an effect, far
more varied and of superior appearance can be obtained by one application than could
be obtained, even by several applications by any other method. Morcover as the
herein mentioned colored varnishes contain no poisonous matter they are of great
sanitary value in internal domestic decoration.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is
The improved method of preparing a gummy varnish coloured or otherwise for
general use or decorative purposes, as described.
