[Alt-photo] Re: Was Sulfamic Argyrotype and toning

[Marek Matusz]

Yes,

It was NaCl,

 

I am not sure which question you are asking.

 

Shelf life of the solution: don't know, just mixed it a few days ago

Capacity for toning: don't know. I tooned just two 8x11 prints, but I am not sure how much platinum I added.

 

I kind of mixed it on the fly and it might not be a standard platinum toner.

I think it is K2PtCl4 ( I am not at my darkroom now), the platinum salt used for platinum printing, it is not the platinum contrasting agent Na2PtCL6. Toning was quick, 1-3 minutes with absolutely no highlight staining.
