Euston Square, in the County of Middlesex, for the Invention of "A NEW
OR IMPROVED CHEMICAL PROCESS FOR CONVERTING OR TRANSFORMING PAPER

MATERIATO"
Sealed the 30th August 1878, and dated the 6th March 1878.
Sealed the 30th August 1878, and dated the 6th March 1878.
PROVISIONAL SPECIFICATION left by the said Adolf Prager at the Office of
the Commissioners of Patents on the 6th March 1878.
ADOLF PRAGER, of Berlin, Prussia, at present residing at Euston Square, in the
County of Middlesex. "A NEW OR IMPROVED CHEMICAL PROCESS FOR CON-
VERTING OR TRANSFORMING PAPER PHOTOGRAPHS INTO OIL PAINTINGS UPON
CANVAS, WOOD, METAL, OR OTHER MATERIALS."
This Invention relates to a new or improved process of transforming or converting
photographs into oil paintings upon canvas, wood, metal, or any other suitable
material. The albuminous coat which covers the photographic paper upon which
the photographic image is received is detached from the paper, and represents a fine
or thin pellicule or transparent skin, upon which is the photographic image.
This albuminous skin or pellicule being wet is transferred to a glass table, and
when it is dry, I apply upon it the oil colours upon the image on the inverse side,
that is to say, upon the side which was adherent to the paper.
•
•
In all the colours employed in my process, I mix about one tenth of tears of
mastic finely powdered.
When the albuminous pellicule or skin has been painted as above described and
is completely dried, it is then transferred on to an ordinary picture canvas, or on to
a wood panel, or on to a metalic plate which has been previously varnished with
mastic varnish, and which varnish has been allowed to dry completely before-
hand

page_text: The canvas, the wood panel, or metallic plate having the albuminous painted
pellicule thereon, is placed between two metallic plates moderately heated and
pressed in a powerful press, until the two metallic plates have become cold.
I take the plates from the press, and the photographic image prepared by this
process represents a perfect miniature upon canvas, wood, or metal, with which the '
thin albuminous coat forms the body by hot pressure. The colours being placed
under the albuminous pellicule, consequently they are not in contact with the
atmosphere, and being fixed by hot pressure, these miniatures are preserved for an
indefinite time.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Adolf Prager in the Great Seal Patent Office on the 6th September
1878.

This Invention relates to a new or improved process for transforming or con-
verting photographs into oil paintings upon canvas, wood, metal, or any other
suitable material. The albuminous coat which covers the photographic paper upon
which the photographic image is received is detached from the paper, and represents
a fine or thin pellicule or transparent skin, upon which is the photographic image.
This albuminous skin or pellicule being wet, is transferred to a glass table, and
when it is dry, I apply upon it the oil colors upon the image on the inverse side,
that is to say, upon the side which was adherent to the paper.
In all the colors employed in my process, I mix about one tenth of tears of mastic
finely powdered.
When the albuminous pellicule or skin has been painted as above described, and
is completely dried, it is then transferred on to an ordinary picture canvas, or on to
a wood panel, or on to a metallic plate which has been previously varnished with
mastic varnish, and which varnish has been allowed to dry completely before-
hand.
The canvas, the wood panel, or metallic plate, having the albuminous painted
pellicule thereon, is placed between two metallic plates moderately heated and
pressed in a powerful press, until the two metallic plates have become cold.
I take the plates from the press, and the photographic image prepared by this
process represents a perfect miniature upon canvas, wood, or metal, with which the
thin albuminous coat forms the body by hot pressure. The colors being placed
under the albuminous pellicule, consequently they are not in contact with the
atmosphere, and being fixed by hot pressure, these miniatures are preserved for an
indefinite time.

page_text: Having thus described the nature of my Invention, and the manner of performing
or carrying the same into practice, I would have it understood that I do not limit
myself to the exact details herein-before described, so long as the main features of
iny Invention are retained, neither do I claim any part of the process or appliances
separately, previously well known, and in common use; but what I claim is, the
new or improved process or processes combined for converting, transforming, or
transferring photographic pictures or images on paper into oil paintings upon
canvas, wood, metal, or other suitable material, substantially in the manner herein-
before fully described.
In witness whereof, I, the said Adolf Prager, have hereunto set my hand and
seal, this Thirtieth day of August, in the year of our Lord One thousand
eight hundred and seventy-eight.
