I’ve only been using distilled water and vinegar… I scrapped everything off the metal plate with a razor blade and soaked it in fresh vinegar… Then I filtered it again and this is what didn’t go back into solution… This makes me want to do more experiments on the other dry concentrates…

what stayed out of solution makes sense with vinegar, silver chloride won’t budge in it. quick check: leave a tiny pinch in sunlight; if it greys over time, that points to AgCl, and a drop of household ammonia usually can clear it :) Also run a magnet across the scrap in case tiny steel from teh razor got mixed in, that can make the residue look odd. defintely keep a small control sample from each batch so you can compare when you run the other concentrates.
I have a stack of samples, including more of that white stuff… I’ll see what happens to the white stuff in the sunlight…
Nice, the sun test will tell you alot. If it greys or goes purple, that definately points to silver chloride, and vinegar won’t move it, so a quick hot-water dip is a cross-check for lead chloride. If it does darken, you can reduce a small pinch with aluminum foil plus baking soda in warm water to prove it’s silver, then keep the bulk for a cleaner run later. Mind keeping one speck sealed in the dark as control so your sure the change is light-driven? :)
Thanks… I already put a capsule of the White Stuff out in the Sun…
