PROVISIONAL SPECIFICATION.
A New or Improved Process and Combination of Materials for the
Treatment of Photographs Previous to Coloring.
I LUCY MATILDA WILLIAMS of 1, Upper Camden Place, Bath in the County
of Somerset, Photographer, do hereby declare the nature of this invention to be as
follows:-
1. Clean the glass with white wax and edge the same with gum, then coat the
waxed glass with collodion & let stand for 6 hours.
2. When thoroughly dry pour a solution of gelatine & glycerine well mixed
over the plate and let stand until quite dry & hard.
3. Then place on the prepared side of the glass (which must be wetted) the
photograph print (also wetted) albuminized side downwards with the squeegee
& let stand for 12 hours.
4. Place the plate in hot white wax photo upwards & let remain until transparent,
then remove from wax & let remain until cold. Then cut the picture round the
inside of the gummed edge & remove the same from the glass. After which
remove the glaze from the print with a knife which will then leave an ivory surface
to the print, & it is then ready for painting. Now place the picture on a piece of
clean glass face downwards, gummed at each corner, & color it with oil paints.
When the photo is quite dry remove the picture from the glass and it is then
ready for framing.

COMPLETE SPECIFICATION.
A New or Improved Process and Combination of Materials for the
Treatment of Photographs Previous to Coloring.
1, LUCY MATILDA WILLIAMS of 1 Camden Place, Bath, in the County of
Somerset, Photographer, 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 :—
My invention relates to a new or improved process in the treatment of photo-
graphic prints, for imparting thereto a perfectly translucent enamelled-or-ivory
surface, sufficiently brilliant to constitute a finished picture, and which may, if
desired, be tinted or colored in an elaborate and most artistic manner by the
application of suitable oil colors upon the back surface thereof, whereby the
lighter or more delicate tints, as well as the heavier or more pronounced colors
appear with added brilliancy upon the face of the picture, and I intend that my
"Mrs. L. M. Williams' Enamel
said process shall be commercially known as,
Process."
In carrying my invention into effect, I procure a sheet of perfectly clear glass,
which I clean with white wax, and edge the same with mucilage, gum or other,
preferably, transparent adhesive substance, the waxed portion of which may then
be coated with collodian, and permitted to stand aside until perfectly dry, which,
under ordinary conditions of temperature will, generally, occupy about six hours,
when, a well mixed solution of gelatine and glycerine, in equal parts or thereabouts,
may be poured over the plate, and again placed aside until quite dry and hard.
The surface of the glass thus prepared is then well wetted, and upon this is

page_text: carefully placed (also wetted) the photographic print, with the albuminized side
downwards, which, after being treated with the squeegee, is put aside and allowed
to stand for about twelve hours, more or less, according to atmospheric conditions,
at the expiration of which time, or any reasonable subsequent period, the whole is
then immersed in a bath of hot molten wax, with the photo print uppermost, and
allowed to there remain until the print becomes perfectly transparent, when it may
be removed from the bath and placed aside until quite cold. I then remove the
picture from the glass by carefully cutting around the gummed edges thereof with
a sharp knife, and by the means of the same instrument I remove the glaze from
the print, thereby leaving upon the picture a clean bright ivory surface, of
sufficient brilliancy to constitute a finished picture, which may then, if desired, be
mounted and framed in the usual way.
If the picture is to be tinted or colored, I place this face downwards upon a
sheet of perfectly clean glass, and retain it smoothly thereon by the application of
mucilage, or its equivalent, at each corner, when, by reason of the perfect
transparency of the picture (rendered so by the process through which it has
passed) every detail of the print will be clearly read upon the back surface, and
may then be painted in oil colors to any degree of artistic finish desired, and when
quite dry the picture may be removed from the glass, when it will be found that
the front of the print has a most beautifully enamelled ivory surface, and showing
every detail of color and tint that has been given upon the back surface, and with
a brilliancy not attained by any system hitherto employed. The picture may then
be mounted and framed in any manner desired.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.
The herein described process, and combination of materials, in the treatment of
photographic prints, for imparting thereto a perfectly transparent enamelled ivory
surface, which may or may not be afterwards colored or tinted by the application
of suitable oil colors to the back surface of same, substantially as herein
described.
