Very informative, what percentage is the silver nitrate solution?

[@JoaoVictor-pb1ji]

How is this silver nitrate solution made?

Peter , what paper do you use to make the Calotypes? Thank you.

[@petermrhar6849]

In this case, I used BankPost by Ratece. But it is 15 years old from my old stock. The company has already failed. Lately I've been using most often the Canson Marker paper.
