Re: Lagrange cyanotype

Loris, thank you very much for the answer.
I think I tried this way also, but it didn't work for me too.
No, I haven't problems with traditional cyanotype (but with the Ware version I have troubles at clearing too).
I just have a kilo of Ammonium Iron Oxalate and I was curious, how this formula works. I am just preparing material for my next show in September (first real alt-exhibition in Slovenia with more than one alt techniques!) and I would like to include as much different variants as I can.
What is solution strength for the Cyanotype Rex (if this is not a formula, you must have pay for?)

I think some time ago you arrage to sell gold chloride (or some similar thing which I don't recall right now) for mixing the gold toner, which is in Istanbul cheaper than in other parts of Europe. I need gold toner for VDBs and salt prints, my Tetenal GT is running out. I am curious if I can make it DIY cheaper.
Please, send me more informations off-list if this offer is still valid.

Regards from Slovenia
Stane Kocar

You may try to coat the paper with only solution A and then develop in
solution B (resuable few times) after the exposure...

This is essentially what our TK calls "Cyanotype-Rex" - except for
slightly different solution strengths. I had bad luck with this type of
formula: strange tonal response (flat and grainy midtones, stair-like
H&D curve) + blue stained highlights (maybe you'll find staining is less
by separating solutions).

Why are you trying different formulas? Is that because you have any
problems with traditional or new cyanotype?

Anybody used Lagrange formula for cyanotype?

I was unable to clear it at all. Maybe someone can help me?
