[Alt-photo] Salted Paper Success

I am sorry to hear about your water problems. My family was flooded to 42 inches deep on the main floor in 1964, so I know how much work it is to clean up the mess. 

I have been printing on HPR exclusively since it first came out. I had a stash of Platine from some time ago, and your section of Christina's book seems to indicate that citric acid in the salting solution makes most papers work, so I tried it. It works, at least on this paper. 

I ordered some carrageenan on Christina's recommendation. I have some experience with agar agar, but I have always found it difficult to work with due to its high gel melting temperature. It will be interesting to see if the acid addition will help make it easier to use. I found some specifications on line that indicate that the melting temperature of carrageenan gel is 50 to 70 degrees C, which causes me to wonder if I might be able to coat it onto paper using a threaded rod, rather than treating it with the acid. I am looking for both a size for salted paper as well as a surface that will work for the final support for carbon transfer. Sandy King's carbon transfer group has done a lot of experimentation with different treatments for art paper for carbon transfer, and I think that some cross-pollination between that knowledge and sizing work done for other processes might prove useful. 

In any case, I will report anything that I learn. 

Thanks again for your contributions to Chris' book, and good luck putting your house back together.

Glad to hear that you are making wonderful prints. It is interesting that you have chosen Platine for the process. When it works it is one of the best papers as it tends to give warmer images with no stain. Apparently the new production of this paper that Chris tested is working well again. 

I have not been able to print anything for months since hurricane Harvey flooded my house.

This made my day. 
Thank you. 
Book writing is sometimes such a thankless task so when you get thanks it makes it all worth it. 
Agar agar (or carrageenan) is the bomb. 
Cheap, too:

That amount will size quite a few sheets of paper! 
Be sure to buy one of those white foam 4” rollers at the hardware store, too.

The combination of citric acid in the salting solution and a double coat of silver nitrate has made all of my salt printing problems disappear. I soaked a stack of Arches Platine (of unknown age) in sodium chloride and citric acid. Double coating with 15% silver nitrate and gold toning (gold/thiourea toner) are giving me a lovely long, smooth tonal scale, good dmax, and lovely clear highlights. The correction curves for my QTR negatives are mild. I think that this will be my process of choice for the foreseeable future.
