Palladium solutions differences

[reinier_de_vlaam]

Hi

 

Can anyone tell me the difference between the Palladium Chloride

mixes I found (Palladium solution no3)

 

Bostick& Sullivan specify

 

Lithium Chloride or Sodium Cloride ((kitchen?? salt)

 

Mike Ware specifies

 

Ammonium Chloride

 

To be mixed with Palladium Chloride to make upto 25ml (5% solution)

 

What is the difference between the 3, I'm looking for a deep warm

black. What would be the best solution

If you're refering to Ziatype (POP)

<P>

I find that the addition of Palladium Solution #3 (from B&S) does indeed give warm black tones. When I add a small amount proportional to the to volume of solution.

<P>

For instance in a recent 8"x10" contact print I used:<BR>

14 drops Lithium Palladium<BR>

14 drops Ferrick Ammonium Oxalate<BR>

2 drops Palladium solution #3 (Sodium Chloropalladite)<BR>

<P>

This gave me a subtle warm tone, more of the #3 solution would have warmed the tones even more. Using too much tends to lose the rich blacks in my experience.

<P>

I haven't used the other formulas you mentioned because the Sodium Chloropalladite gives me the warm tones when I want them.

No, I'm refering to the pure palladium print

 

I just found out that de lithium palladium mix is for Ziatypie,

 

Zo that leaves to mixes for palladium prints, the B&S and the Mike Ware variants. What is the difference between the two?

You can actually use any of them for traditional develop-out platinum printing. They all

produce a slightly different image color. I use lithium palladium for all of my printing

because I like the complex warm brown tone it has when you compare it to the traditional

sodium palladium. The cesium palladium will give a very warm golden brown tone in

develop-out palladium prints. It solarizes badly, though, and you will probably need to

double coat when you use it.

 

For what you want, i would recommend trying the Lithum palladium. It is somewhat

hygroscopic, and tends to keep your paper better humidified than the sodium palladium,

which makes it easier to achieve the deep brown black tones you are wanting.
