Here is the classic method to make nitric acid, worked out early in the forum’s history; (Thanks to Steve and GSP brainstorming),
I find it one of the best ways to make nitric acid without distilling.

The cold method is not good for use with silver (sulfates salts formed make troubles with silver), for silver you should distill the homemade nitric acid to get nitric without any sulfate salts, or buy the nitric acid.
