Folks,
I've no doubt entertained you with some of the rookie mistakes I've made as I've started the refining journey. But with experience comes expertise; at least I hope.
In my first few batches, I've ended up with some filter papers with significant amounts of PM's: undissolved gold from the AR step, gold chloride that I didn't wash up, napkins that I used to pick up gold chloride solution spills, silver powder residues, silver nitrate and silver chloride containing filter papers.
I've read Harold_V's wonderful Incineration thread:

I've seen Kadriver's really good youtube video on this topic:

And of course, I've read Hoke's book where she discusses this starting on page 216.
My questions relate to the salts (chlorides and nitrates) that are in the filter papers. Do fluxes in the melting dish reduce them to metals? If so, which fluxes? Soda Ash?
Or do I need to do a multi step water / acid washes to recover those salts?
Thanks!
