Saltprinting paper - how long before use

[Falkenberg]

I am planning on doing a batch of papers for saltprinting and was wondering how long thy will keep when they are sensitized.

If you mean after applying the silver nitrate, my experience has been only a few hours. I once tried coating about noon, printing a few, then trying again the next morning. The overnight prints were much slower and had much less contrast.

Ditto. ITRC, adding citric acid or sodium citrate to the emulsion may help preserve it awhile.

I did some salt printing several years ago but don't know the answer to your question.

However, it has been my experience that most coated emulsions, including VDB, kallitype, pt./pd. will last much longer if stored in a zip lock bag and placed in the refrigerator or freezer. I made some pt/pd prints a few years ago from paper that was stored in the refrigerator for about a week and they came out very well.

That's a very interesting idea. Thanks, Sandy.
