Okay, that confirms a bit of my assumption what "silver rich" really means, as regards the gelatin/silver mix of the BK formula. If one brushes it on, does it need to dry in between coatings?

The artifact problem with (too much) silver washing out of the emulsion, is there any chemically easy way to remedy this? Is it meaningful to even pursue that? By the way, I like the velvety appearance of non-glossy/untreated papers.

I think the questions sometimes needs to be asked again. The old books are full of good things but sometimes just thinking out loud gets you even further along the road.

I suppose a higher content of NaCl and AG may give better results as more reactions between NaCl and silver can take place, but then there's a price point somewhere along that line...
