sodium chloride for palladium solution
I know it's been discussed here a zillion times, but...
whenever I go to get non-iodized salt (mortons or other) I always see another ingredient listed such as calcium silicate, sodium silicaluminate or yellow prussia of soda...never just plain salt. I know these are anti-caking agents, but can I still use this for my solution with no harm done? I have found sea salt with nothing else listed...or do I need to order NaCl from Bostick or equivalent...?
What to do...?
