In all areas of life, any product may be harmful if not used properly. Of course this applies also to photographic products.
We at MACO care about our customers and our responsibility in regard of environmental aspects.
Therefore we have kept any potential health hazards to a minimum. However
we urge you to use appropriate caution in handling our photographic
See Safety data sheets above.
The use of BLACK MAGIC should take place in a black & white darkroom.
The graded BLACK MAGIC emulsions LPE 210 may be mixed together in any ratio.
Depending on your goal, you should have all necessary components at hand. If you miss an important tool or material during your work it is too late. Most items are ready available in a well equipped darkroom - but some are special and have to be organised before your coating session:
With non-absorbent materials, you can coat up to 8 m², with absorbent materials you can coat up to 4 m².
In practical use, this may vary due to the thickness of the coating and the absorbent properties of the chosen material.
The liquid emulsions LPE210 and LPE310 should be stored in the refrigerator
(6°C-8°C / 40 - 46 F).
All other components, LPE411, LPE520 and LPE610 can be stored at room temperature.
If stored according to our instructions, shelf life will be one year. If you deep freeze LPE210 and LPE310 at temperatures below -10 C° / 14 F shelf life will be extended by far.
|LPE 210: red or yellow green|
|LPE 310: red or light brown, no yellow green|
Keep in mind, that silver halides collect light in difference to the human eye.
Therefore, it is advisable to keep safelight exposure to a minimum. In reality no safelight is really safe - it's just a matter of exposure time. We recommend to do a fogging test under your own conditions - this is especially important if you want to coat large areas or many objects.
Carry out a trial coating and let it be exposed partially by your safelight at the place you want to coat all other materials. Place a black cardboard on top and move it in a way that you have an exposure bracketing of 15 minutes/ 30 minutes/ 45 minutes and so on.
Develop and see whether any exposure shows a gray fogging. If this is the case move or change your safelight.
Depending on the chosen material, the thoroughness of your preparation will be decisive for your final art work.
All materials have to be free from dust and grease. If in doubt clean twice - any trace of grease will lead to adhesion problems.
After you have selected a material to be coated, there is a different approach for 3 main groups of materials:
How to make a baryta solution: (this step may be carried out under normal lighting conditions)
Warm up 1000cc tab water until 70°-80°C and dissolve completely 40 grms of LPE 411 by continuous stirring, until free of lumps. To reduce surface tension you may add a few drops of LP-MASTERPROOF (wetting agent with bactericide and fungicide additives) to your solution, this makes it easier to evenly coat smooth /hard materials. Coat your material directly afterwards. To improve hardening of the emulsion add 20 - 50 cc of BLACK MAGIC additive LPE 520 to your solution. Since you coat under normal lighting conditions even coating will be much easier.
Note about hardening:
You can harden indirectly by adding BLACK MAGIC additive LPE520 to the baryta solution and harden directly by adding BLACK MAGIC additive LPE520 to the light sensitive photographic emulsion (in this case, please use the photographic emulsion within 2 hours). For better adhesion of the coating and to improve mechanical resistance of the surface you may combine both methods.
Furthermore, you can add BLACK MAGIC additive LPE520 directly to the developer.
The graded BLACK MAGIC emulsion LPE 210 may be mixed together in any ratio, to achieve in between grades. For a wide range of contrast control use BLACK MAGIC LPE310.
For absorbent materials use BLACK MAGIC LPE411, it is a purified photo gelatin, much cleaner than gelatin for food, and add for improved mechanical resistance BLACK MAGIC ADDITIV HD LPE520 instructions at the end of this manual, due to its special formula you can add LPE520 also to the emulsion itself and to the developer.
It's much easier to warm up partial amounts of emulsion if you use LPE610, the special bottle is lighttight and thus you avoid warming up the complete bottle - spare time and keep the emulsion quality high.
Spirit (grain alcohol) is recomended in order to get rid of bubbles which almost always occur. Add 10-20cc of it directly into the liquified emulsion (amount based on 500cc). If you have a longer coating session, you can add spirit (grain alcohol) every 20 minutes.
If you decide to precoat your material with BLACK MAGIC LPE411, you can add water soluble photographic dyes to the solution - add as much until you have the desired tone, usually a few drops will suffice.
Take out BLACK MAGIC photographic emulsion of your refrigerator and...
Carry out following working steps under safelight conditions !
Either take out the needed amount out of the bottle by using a solid plastic
or stainless steel spoon fill it into the special bottle (article LPE610)
and liquify it up in a bucket filled with warm water (35-40°C).
For larger application projects warm up the original bottle by the same means.
||For first trial coatings or smaller objects to be coated just take out needed amounts (under darkroom safelight) out of the original bottle , put them into a graduate and liquify by warming up in a container (or bucket) filled with warm water. By doing so you will ensure the quality of BLACK MAGIC (repeated warming and cooling harms light sensitive products).|
If you want to coat larger objects (e.g. ceramics, stones) you may heat them in your oven (30-40°C /86 -104F) so your emulsion won't set while you are still coating.
If you have never worked with BLACK MAGIC photographic emulsion before, you can train the coating procedure with coffee cream since this liquid has a similar viscosity.
You can coat your objects different ways:
|pour and pan||= with flat and rigid materials such as tiles, metal plates etc.|
|pour and brush||= with almost all materials|
|dip and dunk||= with smaller 3-dimensional objects|
|spray *||= with large and complex structured objects|
* Use only spray guns with large jet opening, an air brush is not suitable.Wear protective clothing/mask to avoid inhaling spray particles.
For most applications best results will be achieved by using a brush with natural hair (e.g. Japan brush).
We recommend to coat test stripes at the same time for determining the correct exposure later on. Preferably of the same material or the backside of photographic paper).
Excessive emulsion may be reused immediately.
||By using an spray gun, you can adjust viscosity
with distilled water up to an ratio of 1:1.
By doing so spray several layers.
Cooling and setting stage follows directly after coating. In this stage the coated surface is very delicate. Setting will take about 1 to 2 hours. You can speed up setting by storing the coated materials in the refrigerator for about 30 min. To avoid unwanted exposure either use a light-tight container or unscrew the bulb of your refrigerator.
Now you can dry the coated materials.
You can do so by using a hair dryer at low heat setting and midrange distance to avoid melting of the emulsion. Check hair dryer by turning it on in the dark before using it to make sure there is no electrical spark or glowing of the heat wires which could cause an exposure. Of course you can store objects in your darkroom (Do not turn on room light!) and let them dry off. This will take between several hours and 1 day depending on the kind of object and humidity.
Procedure is similar to standard photographic paper, especially if you have coated flat materials. With 3-dimensional objects close down your enlarging lens to the maximum to reach maximum depth of field. (Note that by stopping down your lens, depth of field will be 1/3 before and 2/3 behind point of focus)
Hint: With cylindrical or evenly formed objects you can produce a large halftone negative(or if you wish also a graphic negative without grey values) by using GENIUS Litho Film. This negative can then be laid or taped onto your coated object (e.g. a bottle or a vase) and then turn it evenly under the enlarging light - by doing so a sharp and even exposure will be a lot easier !
||If you have used LPE310 for coating, you can change
grades for optimum
photographic results. This can be done equivalent to standard variable
contrast photographic papers (e.g. MACO Multispeed 1F and Multibrom F
or AGFA Multicontrast etc.)
either with filters for your filter drawer (e.g. LABOR PARTNER Fil 8,
ORIENTAL Acrylicfilter,or ILFORD Multigrade Filter)
or with enlargers with Variocontrast - or Colorhead by turning the corresponding
Yellow = for softer image reproduction
Magenta = for harder image reproduction
||In case you exposure was to intense, you can bleach until desired density
is reached by using
LABOR PARTNER LP-SEPIA PART A, Art. No. LPH51A, dilution 1+30.
Due to the high silver content, use high energy photographic chemistry only.
LABOR PARTNER photochemistry is especially well suited for BLACK MAGIC. Keep working temperature to a max. of 20°C or lower, to avoid damaging of the emulsion.

A short summary of the attributes of BLACK MAGIC ADDITIV HD LPE520 for liquid B&W photographic emulsions:
LABOR PARTNER BLACK MAGIC ADDITIV HD LPE520 is a new hardener for use in combination with liquid photographic emulsions.
By the nature of liquid photographic emulsions following problems may occur:
The old and now superseded methods of hardening are more painstaking, need a relatively long time of duration before hardening has been achieved. Moreover they have a low efficiency.
Based on new research the use of hardening fixers sometimes mentioned in photographic literature as well as in photographic magazines has turned out to be negative in terms of washing out long term damaging thiosulphate complex as well as silver compounds.
(Even Ansel Adams warned about the use of hardening fixers as archival quality can hardly be achieved).
Moreover, even the best" hardening fixing bath cannot by nature avoid the Lift off" of a liquid emulsion coated object in the developer or stop bath.
LABOR PARTNER BLACK MAGIC ADDITIV HD LPE520 avoids these problems, because, and this is very convenient and successful, it may already be added to the developer.
By this application method the RAPID HARDENING is of great advantage.
LABOR PARTNER BLACK MAGIC ADDITIV HD LPE520 is applied within the BLACK MAGIC Systems of liquid photographic emulsions (resp. comparable emulsions of other brands).
LABOR PARTNER BLACK MAGIC ADDITIV HD LPE520 is a very acidic concentrate with a pH value of 3.
Therefore, for your own safety, please follow the given advice while working
with the concentrate.
Follow strictly the described order of preparation !
For further inquiries regarding BLACK MAGIC ADDITIV HD LPE520, an EU-Safety data sheet is available.
LABOR PARTNER BLACK MAGIC ADDITIV HD LPE520 may be applied by using different methods:
A: Direct adding while preparing b&w paper developer working solution:
|developer concentrate (e.g. LP-BROM 4)|
|LPE 520 HARDENER concentrate|
This procedure is easy to use and efficient for application purposes. It takes advantage of the
RAPID HARDENING mentioned earlier.
It should always be applied (even if other described hardening procedures are additionally used).
If a precoat with BLACK MAGIC LPE411 purified photographic gelatin will be applied; an indirect hardening can be achieved (hardening by diffusion).
Just prepare a working solution of ADDITIV HD LPE520 and add it to your dissolved pure gelatin solution (quantity to be added depending on prepared amount):
B: Preparation of a working solution ADDITIV HD LPE520 for adding purposes:
|distilled water (stir thoroughly)|
|hardening solution ready for use|
Per 1000cc of prepared LPE411 gelatin solution add 20 - 50cc of your working solution LPE520 and mix well. Coating should take place right afterwards.
||If a precoat with LPE411 gelatin is not applied, a direct hardening can be achieved by adding working solution LPE520 directly to the liquified (warm) BLACK MAGIC photographic emulsion. Depending on field of application and thickness of coating add between 10cc and 25cc to 500cc of liquified photographic emulsion. Careful mixing avoids drawing air into the emulsion thus preventing unwanted bubbles.|
With smooth (polished or glossy) hard and non-absorbent objects, e.g. glass
or ceramic tiles, to be coated it may be advisable to combine all 3 methods
in order to avoid adhesion difficulties:
Generally one can rely on the convenient and effective method A" alone.
BLACK MAGIC ADDITIV HD LPE520 in originally closed bottles has a shelf life of at least 1 year, once opened approx. 6 months, provided normal storage.
Prepare only as much working solution of the hardener as needed directly.
If BLACK MAGIC ADDITIV HD LPE520 is used as an additive to developers, shelf life will be according to the data of the developer itself. It´s shelf life, especially in used condition, can be improved by far if kept in tightly closed glass bottles.
For direct application of BLACK MAGIC ADDITIV HD LPE520 in combination either with BLACK MAGIC pure photo gelatine or with BLACK MAGIC liquid photographic emulsions, the question regarding shelf life is not relevant.
Per 500 cc concentrate BLACK MAGIC ADDITIV HD you can prepare up to 10 liters of hardening-developer working solution.
Assortment + packaging:
BLACK MAGIC ADDITIV HD LPE520 is available in bottles with 500cc concentrate.
LABOR PARTNER uses different types of bottles:
BLACK MAGIC HARDENER LPE520, whether in original bottles, or added to developers, or as a working solution, should be stored at room temperature.
(temperature range between min. 5°C - max. 30°C)
