PROVISIONAL SPECIFICATION.
Improved Methods of Obtaining Prints or "Transfers" of Designs,
Patterns, or Pictures, and Reproducing such Designs, Patterns,
or Pictures upon the Surface of China or the like Articles.
We, Sir HENRY DOULTON, (Knight) Lambeth Pottery, Lambeth County of
Surrey, Potter, and JOHN SLATER Nile Street Works, Burslem Staffs, Potter,
do hereby declare the nature of this invention to be as follows:-
This our invention has reference to improved methods of preparing or producing
transfers of designs, patterns or pictures, and the object of our said invention is to
reproduce such designs, patterns or pictures cheaply and quickly upon the vitrified
surfaces of cbina, and the like articles.
One way of carrying our said invention into practice is to paint the selected
design or picture in Brunswick black or monochrome upon one side of a sheet of
glass, this sheet of glass when the design or painting is dry upon its surface we
place with the design downwards upon a photographic plate, the said painted sheet
of glass and photographic plate are then exposed to the light for a suitable length
of time so that a negative of the design or painting is obtained, from the negative
we produce a gelatine printing surface in the customary manner. The design,
pattern or picture we then print from the gelatine on to potter's transfer paper in
any colour usually employed for printing upon china, or we may imprint the said
design, pattern or picture in red oxide of mercury (HgO - 216) or ammoniated
mercuric chloride (NH,HgCl = 252.5). The said print can then be transferred
to the vitreous or vitrified surface of china, earthenware or the like articles in the
usual manner, and after dusting the design, pattern or picture on the articles with
a suitable ceramic colour or colours in a finely powdered state by using a camel-
hair brush or other suitable means, we burn such colours on to such articles in an
ordinary enamel kiln, or we may before firing, transfer the design, pattern or
picture from the gelatine printing surface on to a copper plate or plates, and etch
and bite in such design, pattern or picture on or into such copper plates by means
of a suitable acid or acids.
We may also transfer such design, pattern or picture from the gelatine printing
surface on to a lithographic stone or stones, we then take transfers or prints on to
issue paper from such lithographic stones in the usual way, using heat and printer's
ordinary oil with copper plates, and with the lithographic stones litho' ink or litho'
varnish. After the design, pattern or picture is transferred in the usual way on to
the surface of the ware, a fiuely powdered ceramic colour or colours is dusted or
painted on to the transferred pattern or picture, we then burn such design, pattern
r picture on to the surface of the china or like articles in an ordinary enamel kiln,
and produce artistic effects not otherwise obtainable.

or Pictures upon the Surface of China or the like Articles.
We, Sir HENRY DOULTON, Knight, Lambeth Pottery, Lambeth County of
Surrey, Potter, and JOHN SLATER Nile Street Works, Burslem, Staffs, Potter,
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 our invention has reference to improved methods of preparing or producing
transfers of designs, patterns or pictures, and the object of our said invention is to
reproduce such designs, patterns or pictures cheaply and quickly upon the vitrified
surfaces of china and the like articles.
-
One way of carrying our said invention into practice is to paint the selected
design or picture in Brunswick black upon one side of a piece or sheet of glass,
when the design is dry upon its surface we place such sheet of glass with the
design downwards upon a photographic plate, after the said painted sheet of glass
and photographic plate bave been exposed to natural or artificial light for a
suitable length of time a negative of the design or picture is obtained, from such
negative we produce a gelatine printing surface in the customary manner, we
then rub or spread red oxide of mercury HgO.- 216 or ammoniated mercuric
chloride NH,Hg.Cl, 270.54 upon the said gelatine printing surface, from such
printing surface "transfers" may be obtained in the usual way, and transmitted
from such transfers on to the vitrified or glost surface of china or earthenware,
the imprint on the surface of the ware is then dusted with two or more finely
powdered ceramic colours, after which such decorated ware is fired in an ordinary
enamel kiln to burn such coloured pattern or picture on to the surface of such
ware. Or a suitable stencil or a series of stencils having the design, or a portion
of such design, pattern or picture cut therein may be placed over or on the imprint
of the transfer on the ware, and two or more finely powdered ceramic colours
dusted or painted on to that portion of the imprint of the transfer seen through
the cut out portions of the stencil or stencils used, after which such decorated ware
is fired in an enamel kila to burn such coloured picture, pattern or design on to
the surface of such ware.
Or such design, pattern or picture may be transferred from such gelatine
printing surface on to a copper plate or plates, the design, pattern or picture being
then cut or engraved into the surface of such metallic plate or plates, or such
design, pattern or picture may be etched or bitten into such metallic plates by
means of a suitable acid or acids, after printer's oil and colour or red oxide of
mercury or ammoniated mercuric chloride has been spread over and rubbed into
the incised or engraved portions of such copper plates, and all superfluous adhesive
removed therefrom, transfers are obtained from such incised or engraved metallic
plates in the customary manner and transmitted to the glost or vitrified surface of
ceramic ware, two or more finely powdered ceramic colours being then dusted on
to the imprint ou the surface of the ware, such decorated ware is theu fired in the
usual way.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
1st. The method of preparing or producing "transfers" of patterns, pictures or
designs, and dusting two or more finely powdered ceramic colours. on to the

page_text: imprints of such "transfers," which have been transmitted on to the glost or
vitrified surface of ceramic ware, in the manner and for the purpose as herein
substantially described and set forth.
2nd. The method of preparing or producing "transfers" of patterns, pictures or
designs from an engraved or an incised copper plate or plates, the design, pattern
or picture being first transmitted to such copper plate or plates from a gelatine
printing surface as herein described, "transfers" obtained from such metallic plates
being transmitted to the glost or vitrified surface of ceramic ware in the usual way,
two or more finely powdered ceramic colours being then dusted or painted on to
the imprint on the surface of the ware direct, or through the cut out portions of a
stencil or series of stencils placed in rotation on, or over the imprint on the surface
of the ware in the manner and for the purpose as herein substantially described
and set forth.
