Liquid Photo Emulsion
Coat it Yourself !
I have been making pure silver chloride
gelatin emulsions for 25 years now !
they produce the most beautiful silver prints
you will ever see.
No bromides, No iodides, no sensitizing
dyes, just pure silver chloride in gelatin !
Platinum tones with the brilliance of old
azo like gaslight contact printing papers.
I am offering this photo emulsion now in
liquid form for you to try it, - It is non toxic
with no hazardous ingredients.
Forget Silver Bromide for positive prints.
Discover Grain less Pure Silver Chloride !
- The gelatin emulsion process that
substituted the beautiful albumen Paper
around the year 1890. You will see why.
Now you can Coat your own silver chloride
gelatin emulsion in your own home.
You do not need a darkroom. This emulsion
can be coated at a distance of 8 feet
from an ordinary 25w incandescent bulb.
Just work at night away from white light
sources like fluorescent tubes.
My Manual Tells You How.
It Guides You All The Way Step by Step.
Make Pictures on wood, cloth , fiber paper,
tiles, glass, stones, canvas, plates, etc
Expose in contact with a negative, or enlarge
by projecting the negative image onto the
light sensitive surface. After Exposing develop
and fix in the ordinary photographic manner.
Processing can also be done without a
darkroom at 8 feet from a 25w incandescent
bulb. Basic knowledge of black and white
printing and developing is helpful.
Just Enough Light Sensitivity
For You To Work Comfortably
A Great Advantage Of Pure Silver Chloride
Emulsion (without optical sensitization )
is the fact that you do not need to work under
very low light conditions which lead to many
mistakes ( made in the dark )
and work of a lower quality.
For Fast : 5 s e c o n d s
Exposure Times, Contact Print It
If you want real short exposure times, expose
the coated sensitive material
(flat objects like paper, glass, tiles, boards)
in contact with a negative.
For example:
(see image below)
With The (bw) negative in contact with coated
material directly below a 100w ordinary house
bulb, placed at a distance of 25 cms
( 10 inches) exposure time is about
5 to 10 seconds.
How To contact print:
You Can Make Contact Printer above. Just Tape a
Glass to a Board. Place sensitive material under a
negative. Let the glass down so its weight presses
the negative into good contact with the sensitized
material. The glass will let the light through the
negative to impress the sensitized material below it
when making the exposure to light. In contact printing
the sensitive material must be flat like glass plates,
paper, tiles, metal sheets, boards, canvas, cloth, etc.
Today Large Digital Negatives
on clear acetate are very easy to make.
In Contact Printing,
The Final Image Size will be the
same size as the negative used
27x35mm negs will yield 27x35mm
size images and 6x7 cms negs yield
6x7cms images, and so on.
Projection Printing
and Enlarging
Expose by projecting the negative image
onto coated sensitive material
when the sensitive surface of object is
not flat, like stones, plates, spoons, eggs.
- Or when you want to make images larger
than the negatives you have.
To enlarge or project: use a photo
enlarger or a slide projector.
Silver Chloride Gelatin
Emulsions Can yield Direct
Black or Sepia Tones
On development
With overexposure and long develop-
ment time with diluted developers,
you get beautiful sepia tone prints.
Does away with toning. The silver crystal
is so fine you can also make warm tone
transparencies on glass with the same
exact tones of the I890's !
Or duplicate negatives that will enlarge
10 x With no grain !
Lucenta Pure Silver Chloride Gelatin
Emulsion develops in 30-45 seconds.
with normal short exposures, and
the normal development time of
30 - 45 seconds: you get black tone
silver-gelatin prints.
Color Negatives
can also be printed
by contact, they yield black & white
silver images. Exposure times must
be increased however, to about
20 seconds. (compared with a
black & white negative printed under
equal conditions & similar density.
History
Of Gelatin Silver Chloride
Eder inVienna in 1880 invented silver
chloride gelatin emulsions on paper
and on glass for diapositives.
Under Eder's directions, Dr. E. Just
in Vienna produced in 1882 The first
development paper on a large scale,
then Warnerker followed in London
in 1889, later kodak in 1903 with its
" Velox " gaslight paper and
Liesegang in Düsseldorf with his
"Pan" paper.
Today No one is longer producing
these papers , true gaslight papers
have now disappeared forever.
Lucenta Chloride however is just
such an emulsion in Liquid Form.
Lucenta Chloride
is the Original
Gaslight paper emulsion
now in Liquid Form
A Pure Silver Chloride Emulsion of
the original gaslight paper type is alive
and well for me, I revived it more than
25 years ago and name it: " LUCENTA "
I have improved it ever since to make it
a working tool easy to use in liquid form.
Liquid Light sensitive silver emulsions
are formulated to coat by machinery
immediately after mixing. They are easy to
stabilize because in dry form the coated
silver crystal is is protected against
humidity
Considerable adjustments are required
in formulation, manufacture and presenta-
tion of any emulsion formula when it is to
be hand coated and kept in liquid form,
( permanently humid ready for coating)
a difficult task indeed.
Liquid light sensitive silver emulsions
available in the market today are far
from the best . The silver crystal suffers
changes as it ages in the shelf,
It looses sensitivity, contrast, or starts
fogging. The Gelatin, its vehicle, also
degrades under the action of bacteria
or the antiseptics added. Gelatin looses
strength in humid condition, sooner or
later it hydrolyzes.
with Lucenta.
You will get only freshly made
silver emulsion every time.
This I can guarantee because I will make
Lucenta only when you order it , I do not
have a mechanized factory. Lucenta, like
your work, is a hand made product with
attention to quality not quantity .
My relation with you will be person to
person, or artist to artist.
Lucenta Chloride
Is the Fastest Drying Liquid
Emulsion Available
and has the longest shelf life !
Lucenta comes without water
in dried sheets.
Since It does not come in liquid or
humid form , You have the option to
either dissolve the dried emulsion
in pure water, or alternatively ,
for rapid drying :
water with a high content of
ethyl alcohol.
This outstanding feature allows
for over 100% faster drying times !
plus: emulsion spreads very easy,
is absolutely " bubble free "
and gelatin will not spoil if kept
un refrigerated.
Besides that enormous versatility with
Lucenta in dried form, You
also have these other advantages:
FIRST: It will always be fresh.
-You can Dissolve only the quantity you
think you will need for a given task
and only when ever you are ready
to use it.
SECOND: you can Concentrate it
for example:
-Instead of dissolving it in the normal
amount of solvent,
you can dissolve it in only half the amount
of specified solvent to get a fast drying
(not dripping or too thin) concentrated
emulsion.
This is important for difficult coating tasks,
- like coating an egg for example.
Coating chicken eggs with silver
emulsion perfectly is now
possible and easier. Also, difficult concave
shapes like spoons and irregular
surfaces like stones and sea shells are
attainable realities for the first time.

Liquid Light Sensitive Silver Chloride Emulsion
Coated On Glazed Ceramic Tile In the Year I990
Gelatin Silver Prints On Glazed Ceramics are extremely
Permanent and are easy to coat. 5 ml of Lucenta Chloride
is more than plenty to coat a tile 6x6 inches. A pre coat of
plain colorless and flavorless food gelatin diluted with flat beer
will assure
perfect adhesion during processing, Formulas and Directions are Given in the Lucenta Chloride Manual. Diapositives On glass Are also Superb.
Image above was developed in agfa's newtol paper developer.
If developed with hydroquinone you will get the tones exactly as given by Eder himself when he first invented Gelatin Silver Chloride Emulsions back in December of the year of I88O.
Making Stones Photographic With Liquid Light Sensitive Silver Chloride Emulsion
Coating Stones with LUCENTA
is not difficult because it has
great covering power.
I gave This stone first a pre coat
of a homemade paint made with
gelatin, chalk, and yellow ochre
as pigment to give it a light yellow ground color. ( 3-4 coats)
Silver emulsion was applied with
a soft camel hair brush.
First coat: very thin and even.
stone was placed in front of a current of cold air from a fan and
After about I5 minutes, second
coat was applied also very thin,
with care not leave thick pools
of emulsion which will not be dissolved completely in the fixing bath, this common error is the number one failure of emulsion users. Unfixed silver is still light sensitive and will darken on exposure to light sooner or later, appearing as dark blotches or spots, in a period of 24 hours for bad cases or worse still after a
few months, when you have no longer power to correct it.
For this reason when coating stones I do not flow the emulsion
on it or dip the stone in a pool of emulsion; as recommended by some liquid emulsion manufacturers, brush is much safer, and entirely satisfactory, it leaves thin and even layers that will fix rapidly and completely in about 5 minutes in the thiosulfate
fixer.
The second fatal most common error is overworking the fixing
bath. If you want your grand children to see your silver prints:
always use a fresh (unused) fixer as your last bath. I repeat:
USE USED FIXER AS A FIRST BATH: 5 MINUTES
BUT THE SECOND 5 MINUTE BATH HAS TO BE FRESH UNUSED
FIXER.
The work above is about 15 years old.
It would be in a terrible condition by now if:
I) emulsion was applied too thick and uneven
2) and last fixing bath was not fresh and unused.
Image on Stone is a 3x enlargement from a 35mm bw negative.
Coating An Egg With Liquid Silver Emulsion
The Most Difficult Silver
Coating Task I have ever encountered is coating eggs
to make pictures on it.
( also stones and metal spoons)
I mean perfect, professional
looking pictures without marks
or streaks, permanent pictures
that will stand the test of
time and with portraits of people
which will not accept blemishes
on their faces,
Not the images I have
seen sometimes on eggs and
sea shells which have unintended
uneven density, which besides
having an unprofessional finish,
they are liable to stain, or bleach in blotches sooner or later
yes, it was a difficult task, but
After countless failures I found success when I dehydrated the
emulsion, that is, dehydrated it until it had no water in it.
Then I re dissolved it in the dried form in fast evaporating
ethanol, plus only half the normal amount of water, thus:
Distilled or rain water .....60 ml
ethyl alcohol ............ .....40 ml
dried Lucenta emulsion....2 grams
I had then a Fast Drying Concentrated Emulsion that would
not run when applied with a small soft hair brush. Problem
was solved. I will not coat these objects now any other way.
It is impossible to do this type of challenging high
quality work with current silver emulsions in liquid form in the
market today. They are just too runny and spill all over. It
does not matter if you spray it, if it has high silver content or
you lower the coating temperature, or whirl the object until the
emulsion sets, or even built special silver coating machinery
like I did: bad results every time !
They just not fit for these and many other jobs.
LUCENTA CHLORIDE Comes in DRIED FORM, Ready For The Task!
MAKE THE EMULSION YOURSELF !
Now You Can Make Ultra Rapid Silver Chloride Emulsions at Home!!!
In the year 2006 Saul Bolanos Working In Costa Rica Invented a process to purify gelatine. Also in same year; produced new types of gelatine sensitizers and restrainer as well as a series of proprietary proteins that when added to the purified Photo gelatine:
INCREASED THE LIGHT SENSITIVITY FOR SILVER CHLORIDE EMULSIONS BY 50 to 100 TIMES !
With this historical breakthrough, All you need is the LUCENTA CHLORIDE GELATINE, and Silver nitrate to Make Rapid Silver Emulsions at Home in Less Than 45 Minutes.
The New Gelatine Comes in Granules, is not Light Sensitive, keeps indefinitively, it is Non Toxic and Harmless. It can be Shipped anywhere, No trouble with Custom Inspectors.
Never in the History of Silver Halide Darkroom Photography has Emulsion Making being so Easy, so Fast, So Certain and of such a Low Cost.
Finally an " INSTANT PHOTO EMULSION " has been invented that you can make yourself.
Note that this is not the classical LUCENTA CHLORIDE SLOW EMULSION described above that you do not need a darkroom for, This photo emulsion that you can make yourself needs a darkroom and must be handled by red or orange light . It is as rapid as the average silver bromide liquid emulsions available.

What you will need to make the photo emulsion yourself, besides our rapid gelatine is:
Silver Nitrate
Which You Can Buy at your locality in a chemical supply house for 0.50 to 1.00 USD per Gram.
To Make Half of Pint of Photo Emulsion Yourself Will Cost Less Than $ 15 USD. That is about Half the price that you will pay for a half of pint (250ml) of a good quality commercial liquid emulsion.
To Make a half of pint (250ml) of Photo Emulsion yourself proceed as follows:
By Normal Room Lights, dissolve:
Silver nitrate....................6 grams
Distilled water.................60 ml
(Water at room temperature)
Set aside until needed.
Use gloves to prevent silver stains.
In a separate glass dish, Soak:
LUCENTA Gelatine.............24 grams
Distilled water....................180 ml
Leave gelatine soaking at room
temperature for at least 5 minutes.
Next Precipitation step is done In Darkroom by red or dark orange Lights.
After melting the rapid gelatine for 15 minutes in a hot water bath at 50c /122f
By red light; Add the silver solution in 5 to 10 seconds to the gelatine solution while stirring briskly with a spoon or fork.
Once the silver is mixed with the gelatine, harmless silver chloride suspended in gelatine is formed. Emulsion is absolutely non toxic.
Continue heating for 20 minutes at 50c/122f, at the end of that time add: 12 ml of a 10% citric acid solution as an antifoggant. The half of pint (250 ml) of emulsion is ready. It can be coated as soon as it cools or stored under refrigeration where it will keep for more than 6 months uncoated.
