For a newbie with an interest in Kallitype and Argyrotype, how critical are sources of silver nitrate and silver chloride?
A few years ago when I imagine there was less scrutiny of chemical purchases, I found a source of 'recycled photo-grade' silver nitrate in quantities of 100 g or so, something on the order of US$60...looked like a good deal. Never ordered any, wasn't ready yet.
Today on a whim I searched eBay stores for silver nitrate, not expecting anything but there is a seller claiming 'best web prices or something to that effect. 125g for $70 for technical grade. They had a simple explanation of their sources and refining process.
I see there is USP grade, technical grade, and 'chunky style '.
In the context of my leading question, how critical is this, and any idea what the 1-5 gram chunks would be good for?
Thanks
